5. High Energy and High Voltage DANGER

High energy and high voltage up to 480 V AC are used in the operation of power and cooling equipment. This high voltage poses a significant risk of shock or electrocution. Batteries can store large amounts of energy. Direct contact with battery terminals or any indirect contact via cables or damp items can result in dangerously rapid discharge of this energy, resulting in fires or personal injury.

• The work shall be performed and supervised only by personnel knowledgeable about the risks involved, and trained in the safety measures that must be followed.

• Metal objects such as rings, watches, bracelets, etc. that may cause short circuits in the equipment, must not be worn when working on or around any live equipment.

• The tools that are used on live equipment shall be factory insulated to IEC 900 standards for insulated hand tools. (Tools insulated with insulating tape are not acceptable under any circumstances.) The tools shall be inspected for damage prior to the start of each shift. Do not try to repair a faulty tool yourself.

• All battery cables shall have both ends marked to prevent unintentional short circuits.

• It must be possible to disconnect the load, the AC- and the DC-supplies from the power supply/cooling system, should this be necessary. The AC-disconnectors must be designed so that all the phases can be cut off with one manipulation. Local rules must be adhered to.

• The unit in question shall if possible, be de-energized before the work starts applying established procedures. Note that there might be more than one feeding to the unit and that filters of the unit may be charged even if the supply voltage is disconnected.

• Charged cells in a battery have a short circuit effect. A short circuit between the poles may cause dangerous burns and a spark formation may cause bursting of cells. Therefore, do not place any units of unmstalled metal in the vicinity of the batteries and protect the battery terminals from physical contact.

• Switch off the power supply if the equipment is damp inside.

• Prevent moisture from entering the equipment

• Before the power supply to the equipment is switched on. (before testing or after repair) all tools and other objects not associated with the equipment must be removed.

• To avoid static build-up while working on batteries, maintenance personnel should periodically have contact with ground.

6. Thunderstorms

DANGER

Avoid working with electrical installations or being close to towers during thunderstorms.

• Thunderstorms generate strong electric fields that may result in lightning strokes. It is essential that equipment and facilities be properly earthed to minimize the risks of personal injury and equipment damage.

7. Explosive Gases DANGER

The batteries contain potentially explosive gases, which may be released during charging or on abnormal operating conditions, such as rectifier malfunction or high temperature.

• Fire in any form, spark formation, or smoking is not allowed in battery rooms or in the vicinity of batteries.

• The battery manufacturer's safety recommendations shall be followed.

8. Acid WARNING

The batteries contain sulphuric acid, which is very corrosive and can cause severe bums. Impact can cause the battery case to rupture.

• Protect eyes and skin from splash (ventilated cells) with protective goggles and protective clothing. In case of skin contact with electrolyte, remove contaminated clothing and flush affected areas thoroughly with water. If eye contact has occurred, flush for a minimum of

15 minutes with large amounts of running water and seek immediate medical attention.

• Keep batteries of ventilated type upright.

• The battery manufacturer's safety recommendations shall be followed.

DIRECTIONS FOR USE - BZA 108 35

1 Introduction The NetSure™ 501 -48 V DC power system consists of a stand-alone cabinet, DC-distribution unit, maximum 12 rectifiers of 1700 W, battery connections and a supervision unit.

2 Function For the protection of the batteries during a power outage, the load is disconnected at a preset voltage or after a predetermined delay.

To prolong the service of some loads at a long power outage, the DC distribution is divided into two branches. One is for normal load and one for priority load, so the disconnection can be made in two steps.

4 Units in the system

4.1 Rectifier The rectifier is voltage regulated of a constant power limitation type (1700 W) and designed to meet the most stringent electrical requirements as well as demands for high power density (fan cooling). It can work independently of the control unit, and can share the load actively and control the system voltage.

Figure 5. Rectifier.

4.1.1 LEDs The front panel has three indicator LEDs. The functions of the LEDs are listed in the table below.

4.1.2 Features • Hot swappable. The rectifier is plug-and-play to live inputs and outputs.

• Active load sharing. The rectifier uses advanced digital active [oad sharing technology for minimum load difference between units.

• Power derating bv input voltage. The rectifier will go into power derated mode if the input AC voltage is too low or too high.

• Power derating bv output load. The rectifier will limit its output power constant when the load exceeds the nominal output power.

• Power derating bv temperature. For high temperatures the output load will be gradually reduced. See technical data.

• Current limiting function. The rectifier has a current limiting function. The current limit can be set from an SCU/ACU.

• Foldback current limiting function. If a short circuit occurs on the rectifier output terminals, the rectifier will keep its output current at a constant value. When the short circuit fault is cleared, the rectifier will automatically restore to normal operation.

• Adjustable output voltage. The voltage can be set from an SCU/ACU.

• Current walk-in. The rectifier can be set from an SCU/ACU to take load gradually in order to reduce the stress on generators, fuses etc.

• Fan control. The fan's speed is controlled according to the rectifier internal temperature. The fan is stopped completely at low temperature and at very low or high input voltage.

4.1.3 Digital Signal Processor (DSP) The rectifier has a built-in advanced DSP that monitors and controls the operation of the rectifier. The DSP also communicates with an SCU/ACU through a CAN bus.

• The rectifier can receive commands such as turning on/off, current walk-in on/off signal and high voltage alarm reset signal from an SCU/ACU.

• An SCU/ACU can adjust the output voltage, overvoltage alarm point, current walk-in time and the current limit of the rectifier.

• The rectifier reports its output voltage, output current, temperature, current limit setpoint, overvoltage setpoint, on/off status and alarm information to an SCU/ACU in real time.

• By querying the DSP, an SCU/ACU can get the following data from the rectifier: Input voltage, output voltage, output current, current limit setpoint, temperature of rectifier, and overvoltage setpoint.

8.3 Alarms 8.3.1 Alarm categories

The different alarm categories used in the power supply system are Critical, Major, Observation and No Alarm.

An alarm of category Critical requires immediate action, whatever the time of day or night.

An alarm of category Major requires immediate action if it occurs during working-hours, otherwise as soon as the working-hours commence.

An alarm of category Observation is an alarm that indicates a temporary state of operation and does not normally require any action, However, if the alarm persists for more than 20 hours, it must be investigated.

If an alarm has category No Alarm it means that the alarm is deactivated and will not be shown in the display of the SCU/ACU.

8.3.2 Procedure in case of alarm Enter in the logbook of the power supply system all observations made at the moment of failure, such as date, time, system voltage and rectifier load. Enter also what alarm(s) are shown and any external disturbance such as thunderstorm or mains failure.

Trace activated alarms by means of the alarm survey of the respective unit and the item, which describes what actions to take on the respective alarm.

Table 1. SCU alarm categories.

The audible alarm is silenced if the user presses any key on SCU, if the fault that triggers the alarm is cleared or after 10 min (settable). The audible alarm can be disabled from a menu in the LCD display.

The alarm LED stops emitting light if all the faults that trigger the alarm are cleared.

1.1.2 Input/output terminals Eight configurable digital inputs are provided on the connector board placed above the SCU. The connections to the connector board are described in the INSTALLATION INSTRUCTIONS for the respective system.

Eight potential free relay outputs are provided on the connector board. There are both closing and opening contacts on each output.

Three of the relays are default configured and mapped to alarms of the following alarm severity:

Relay 1 Opened: normal operation Closed: critical alarm (Critical) indicating that the power system's continued operation may be at risk and that the supply of the priority loads is, or might soon be affected. Immediate action is required.

Relay 2 Opened: normal operation Closed: alarm (Major) indicating a failure that requires action when convenient from the point of view of workload.

-j Relay 3 Opened: normal operation Closed: alarm (Observation), signalling that the power system does not perform to its maximum but that the loads are not affected. No action is required.

Each relay is individually configurable, using the graphical display. Any alarm signal available in the system can be connected to a relay output.

2 Software functions

2.1 Control functions

2.1.1 System voltage The set voltage of the rectifiers is configurable from the SCU.

In case temperature compensated battery charge is activated the voltage will be adjusted in accordance with the battery temperature.

2.1.2 Temperature compensated battery voltage To compensate for some of the negative effects on batteries caused by high ambient temperatures, this function can be used. However, it requires connection of a temperature sensor.

The function adds a correction term related to the temperature of the batteries to the nominal value of the system voltage. The degree of regulation can be set.

The maximum influence, • U of the function, is ±2 V from the nominal system voltage.

The temperature compensation is disabled if there is a rectifier communication failure, DC over/undervoltage or a low voltage disconnection.

• Tnom: Nominal temperature +20 °C (no compensation is done at this temperature).

• Tupper: Upper temperature where compensation ends, +40°C.

• Ticker: Lower temperature where compensation ends, 0°C.

2.1.3 Battery boost charging Boost charging voltage is used to reduce the charging time after a mains failure and to equalise the charge level of the batteries. The charging function can be initiated cyclically, automatically or manually. The battery manufacturer's instructions for boost charging shall be observed.

Start of charging When the battery charge current exceeds a preset value for 3 minutes or if the calculated battery capacity has decreased to a preset value (after a mains failure, for example), the charging function of the SCU is activated. A charging signal is sent from the SCU to the rectifiers to increase the voltage up to the battery charging level U3.

Battery current limitation

After a mains failure or when some battery cells are permanently damaged, the current to the batteries can be quite extensive. To avoid overheating or further damages to the battery, the SCU will limit the battery current to a preset level by limiting the charging voltage of the rectifiers. Should the battery current still exceed a higher preset value an alarm will be issued.

Stop of charging When the charging current drops below a preset value a defined prolonged charging time is started before the charging is stopped and the voltage of the rectifiers returns to the float charging level (U-i). For security there is a boost charging limit time that stops the charging after a preset time.

2.1.4 Very high battery temperature handling If the battery temperature exceeds the very high battery temperature alarm level, the system voltage will be reduced to the defined voltage for this function.

2.1.5 Battery test The battery test has three modes, short time test (requires two battery shunts), time test and stable current test.

Battery tests can be started either manually or automatically at scheduled times for regular test of battery status.

For manual battery tests as well as for cyclic battery tests the following parameters must be set: End voltage, Test time and Battery capacity discharge limit.

Figure 5. Battery test diagram.

The battery tests follow the procedure described below:

• In time test mode, the output voltage of the rectifiers is reduced so that only the batteries power the load. If the batteries fail, the rectifiers will power the load.

• In stable current test mode, the output voltage of the rectifiers is reduced so that the batteries give the preset test current to the load.

• This test will continue until one of the following three situations occurs:

• The preset test time, see Figure 5, expires. The battery has passed the test.

• The battery voltage drops below the preset end voltage level (U8nd) (Figure 5). The battery has not passed the test and the test is interrupted.

• The battery capacity drops below the preset Test end battery capacity. The battery has not passed the test and the test is interrupted.

• An alarm is issued in the system.

5/1553-BMP 903 051 Uen Rev A 2005-07-05

9(19)


• After the test, the output voltage of the rectifiers will increase again so that the rectifiers feed the plant and charge the batteries.

2.1.6 Backup control To prevent serious damage to the batteries during a long mains failure the loads can be disconnected by voltage-, or time-control, if LVD contactors are included. The software supports load disconnection in to two steps. Load disconnection can be activated at AC mains failure only.

Load reconnection is made automatically on the return of AC mains.

2.1.6.1 Voltage controlled disconnection

When the set voltage level is reached the backup batteries are disconnected from the selected loads.

2.1.6.2 Time controlled disconnection

When the set time has elapsed the backup batteries are disconnected from the selected loads.

2.2 Supervision functions

2.2.1 Fuse (circuit breaker) alarms If a distribution or battery fuse (circuit breaker) that has a load connected has released due to overcurrent or short-circuit or has been removed/manually released, alarms are initiated.

2.2.2 Voltage alarms One overvoJtage and two undervoltage levels are supervised.

2.2.3 Battery temperature supervision The battery temperature can be supervised by the means of a temperature sensor mounted on one battery cell.

Alarms are provided in two steps in case of high temperature.

There Is also an alarm at low battery temperature.

2.2.4 Ambient temperature supervision

Alarms are provided in case of high or low ambient temperature.

2.2.5 Mains supervision In case of mains failure from all rectifiers, the SCU detects it as a general mains failure.

2.2.6 Rectifier supervision In case of mains or rectifier failure, alarms are sent to the SCU.

Alarm settings

From these menus it Is possible to configure alarm type and level for the output alarm relays and to activate the digital signal inputs. Furthermore the audible alarm can be blocked and the alarm history can be cleared.

Battery settings

From these menus all the battery management configurations are set.

When setting the battery capacity it must be observed that the SCU regards an individual battery as the battery string(s) connected to one measuring shunt. As there normally is only one shunt in the system, it means that the value of the total battery capacity in the system should be used when configuring the battery settings.

Note: The function "Short test" should be set to N (no), as it cannot be implemented in systems with a single battery shunt.

3.2.5.3 AC settings

From these menus the AC voltage alarm levels are set.

Note: This function is not supported.

3.2.5.4 DC settings

From these menus the DC voltage and ambient temperature alarm levels are set.

3.2.5.5 Rectifier default settings

Individual rectifier output voltage and current limitation can be set from these menus. The individual values are used if the communication with the SCU fails. The walk-in (soft start), the fan speed and the high voltage shut down functions can also be configured from these menus.

3.2.5.6 System settings

System parameters like language, date, time, modem communication speed, password and system type are set in these menus.

USER'S GUIDE - ACU for NetSure™ 201, 501, 701 and 801

1 General ACU is an advanced control unit used in DC power supply systems NetSure™ 201,501, 701 and 801. Itcommunicateswith the other units of the power supply system like rectifiers, LC and SM modules (SM IO, SM BAT and SM AC) and manages alarm handling, data processing, voltage control, etc.

The ACU can monitor the power system locally and from a remote management system.

1.1 Alarms The control- and the rectifier-units are equipped with LEDs that provide relevant information regarding system- and unit-status, and guide the service technician to the right unit in case of trouble.

The alarm events are classified into different alarm categories. Different alarm categories have different visual/audible alarms and alarm callback activities.

Alarm Category Red LED Yellow LED

Alarm Buzzer

Alarm Callback

Remark

Critical Alarm ON ON Yes Callback function enabled

Major Alarm ON ON Yes Callback function enabled

Observation Alarm

ON OFF No

No Alarm OFF OFF OFF No Table 1. ACU alarm categories.

The audible alarm is silenced if the user presses any key on ACU, if the fault that triggers the alarm is cleared or after 10 min (settable). The audible alarm can be disabled from a menu in the LCD display.

The alarm LED stops emitting light if all the faults that trigger the alarm are cleared.

Figure 1. ACU with connection board.

Eight configurable digital inputs are provided on the connector board placed above or beside the ACU. The connections to the connector board are described in the INSTALLATION INSTRUCTIONS for the respective system.

Eight potential free relay outputs are provided on the connector board. There are both closing and opening contacts on each output.

Note: When either the ACU or the connection board is disconnected from the back plane board the output terminals have no connection to the re/ays.

Three of the relays are default configured and mapped to alarms of the following alarm severity:

Relay 1 Opened: critical alarm (Critical) indicating that the power system's continued operation may be at risk and that the supply of the priority loads is, or might soon be affected. Immediate action is required. Closed: normal operation.

Relay 2 Opened: normal operation Closed: alarm (Major) indicating a failure that requires action when convenient from the point of view of workload.

Relay 3 Opened: normal operation Closed: alarm (Observation), signalling that the power system does not perform to its maximum but that the loads are not affected. No action is required.

5/1553-BMP 903 050 Uen Rev D 2007-07-05 5(37)


1.2.1 Communication with SM modules The ACU acquires data from SM modules (SM IO, SM BAT and SM AC) through an RS485 port on the connection board. See Figure 1.

1.2.2 Web communication The Ethernet port of ACU is used for Web communication via LAN or Internet. It can also be used for direct connection to a PC.

1.2.3 Remote communication with management systems

Figure 2. Remote communication to the ACU.

The ACU supports the EEM, RSOC and SOC/TPE protocols. These protocols are used to communicate with a power management system.

For the communication, an RS232 port is provided at the connector board for direct connection or via a PSTN modem. This port has two DB9 contacts, one at the front of and one inside the unit. See Figure 1. Default setting of the port: 38400 bps, 8 data bits, 1 stop bit, no parity and no data flow control-As an alternative, the Ethernet port can be used for direct or LAN connection.

1.2.4 SNMP communication SNMP communication can be established via LAN.

1.2.5 Console port The RS232 console port is for factory use only.

2 Software functions

2.1 Control functions

2.1.1 System voltage The set voltage of the rectifiers is configurable from the ACU.

In case temperature compensated battery voltage control is activated, the voltage will be adjusted in accordance with the battery temperature.

2.1.2 Temperature compensated battery voltage

To compensate for some of the negative effects on batteries caused by high ambient temperatures, this function can be used. However, it requires connection of a temperature sensor.

The function adds a correction term related to the temperature of the batteries to the nominal value of the system voltage. The degree of regulation can be set.

The maximum influence, "delta" U of the function, is ±2 V from the nominal system voltage.

The temperature compensation is disabled if there is a rectifier communication failure, DC over/undervoltage or a low voltage disconnection.

2.1.3 Battery boost charging Boost charging voltage is used to reduce the charging time after a mains failure and to equalise the charge level of the batteries. The charging function can be initiated cyclically, automatically or manually. The battery manufacturer's instructions for boost charging shall be observed.

Start of charging When the battery charge current exceeds a preset value for 3 minutes or if the calculated battery capacity has decreased to a preset value (after a mains failure, for example), the charging function of the ACU is activated. A charging signal is sent from the ACU to the rectifiers to increase the voltage up to the battery charging level U2.

Battery current limitation

After a mains failure or when some battery cells are permanently damaged, the current to the batteries can be quite extensive. To avoid overheating or further damages to the battery, the ACU will limit the battery current to a preset level by limiting the charging voltage of the rectifiers. Should the battery current still exceed a higher preset value, an alarm will be issued.

Stop of charging When the charging current drops below a preset value, a defined prolonged charging time will start before the charging is stopped and the voltage of the rectifiers returns to the float charging level (Ui). For security, there is a boost charging limit time that stops the charging after a preset time.

2.1.4 Very high battery temperature handling

If the battery temperature exceeds the very high battery temperature alarm level, the system voltage will be reduced to the defined voltage for this function.

2.1.5 Battery test The battery test has four modes, short test (requires two battery shunts), AC fail test (at mains failure), planned time test and stable current test.

Battery tests can be started either manually or automatically at scheduled intervals for regular test of battery status.

For manual battery tests as well as for AC fail tests and cyclic battery tests, the following parameters must be set: End voltage, Test time and Battery capacity discharge limit.

Figure 5. Battery test diagram.

The battery tests follow the procedure described below:

• In time test mode, the output voltage of the rectifiers is reduced to the test voltage so that only the batteries power the load. If the batteries fail, the rectifiers will power the load.

• In stable current test mode, the output voltage of the rectifiers is reduced so that the batteries give the preset test current to the load.

• This test will continue until one of the following four situations occurs:

V The preset test time, see Figure 5, expires. The battery has passed the test.

V The battery voltage drops below the preset end voltage level (U6nci) (Figure 5). The battery has not passed the test and the test is interrupted. An alarm "Bad battery" is issued in the system.

V The battery capacity drops below the preset Test end battery capacity. The battery has not passed the test and the test is interrupted. An alarm "Bad battery" is issued in the system.

• After the test, the output voltage of the rectifiers will increase again so that the rectifiers feed the plant and charge the batteries.

5/1553-BMP 903 050 Uen Rev D 2007-07-05 . 9(37)


• The ACU will record the battery test start/end time, battery test voltage and battery remaining capacity in the battery test log. 10 groups of battery test data can be recorded. The user can query the test log from the ACU through the Web interface or via EEM.

• If the "AC Fail Test" is enabled, the test log will also be issued at a mains failure. The set values for test time, end voltage and end capacity will be the same as for "Planned test". Should any of these values be exceeded during the mains failure the alarm "Bad battery" is issued in the system.

2.1.6 Backup control To prevent serious damage to the batteries during a long mains failure the loads can be disconnected by voltage-, or time-control, if LVD contactors are included. The software supports load disconnection in to two steps. Both LVD contactors can be set individually to voltage or time disconnect. Load disconnection can be activated at AC mains failure only.

Load reconnection is made automatically on the return of AC mains.

2.1.6.1 Voltage controlled disconnection

When the set voltage level is reached, the backup batteries are disconnected from the selected loads.

2.1.6.2 Time controlled disconnection

When the set time has elapsed, the backup batteries are disconnected from the selected loads.

2.1.7 Energy management Energy management is an advanced function, which can save money for customers. It includes:

2.1.7.1 Energy saving

• Reduces the mains energy consumption during high tariff periods,

• Can make the power consumption rate lower than a given limit.

2.1.7.2 Rectifier redundancy

• Switches ON/OFF the redundant rectifiers according to maximum and minimum redundancy percent.

• Rectifier cycling will regulate the total work time of each individual rectifier to the average work time of all rectifiers.

2.1.8 Power Split The power system with the ACU can act as a slave system to share load (split output) with an existing master system that needs extension. The ACU does not need to communicate with the master system control unit. See separate document.

5/1553-BMP 903 050 Uen Rev D 2007-07-05

Description of SNMP

SNMP is a technology used for network management. The technology is based on implementing an information base called MIB (Managed Information Base). This MIB contains parameters that are interesting from a management perspective. All LAN connected equipment that support SNMP shall also support a default MIB called MIB-II.

The SNMP Agent responds to requests received via the SNMP protocol and also actively sends traps to a specified manager when certain MIB values change state. This is used to actively inform a manager when an alarm situation is recognised.

The PCU supports MIB-II and Emerson's powerMIB, rev B. Contact Emerson Energy Systems for more information.

1 Tables of set values These tables are based on the ACU software revision 1.40, for NetSure™ 201, NetSure™ 501 , NetSure™ 701 and NetSure™ 801, -48 V.

All settings and choices affect the functions of the power supply system. The values shall therefore not be changed without a consequence analysis.

If a default value Is adjusted, the new value shall be entered In the column "Plant-specific setting". The default settings listed are the factory default settings.

Wofe; The appearance of some settings will depend on what configuration package file has been downloaded to the ACU.

2 Device Explore Note: When browsing the control and settings of the system devices, some settings

will be blocked (the set button is grey). The reason is that the setting depends on another setting or that the user authority level does not approve a change of the setting.

2.6 Earthing

Power cabinet Telecom rack

Figure 13. Earthing principle of the /VefSure™ 501

AC mains protective earth

The rectifier subracks have internal multipoint earthing. The mains PE and the rectifier enclosures are interconnected to the subrack mechanical structure.

DC system earth

A 25 mm2 cable links the mechanical structure of the cabinet to the system 0 V bar. This link is essential if a DC short-circuit occurs between live pole (negative) of the system and the cabinet mechanical structure as it will protect the mains PE conductors from overload.

Bonding to the main earth terminal

1. Check that there is an insulated 25 mm2 cable connected between the 0 V (+) terminal of the power supply system and the earth terminal inside the top of the cabinet.

2. Connect an insulated cable, minimum 25 mm2, between the 0 V (+) terminal of the power supply system, or the earth terminal on the top of the cabinet, and the earth collector bar (MET). See Figure 13.

16(26)


Telecom earth

The telecommunication equipment should be connected to the MET according to its specific requirement. The cabinets can be earthed via the power cabinets or directly to the MET.

2.7 Battery connection Note: Great energy hazard when working with batteries. Short-circuit current >1000 A.

Note: For safety reasons, leave out one of the inter-cell connectors until the appropriate stage in the commissioning of the power supply plant. If internal Emerson batteries are to be used, the cabinet is normally equipped with suitable battery circuit-breakers and pre-cabled from factory for the selected batteries.

1. Check that the battery CBs are switched-off.

2. Connect the battery cables to the battery terminals (-) and (+).

At external batteries, the cables should enter the flexible cable inlets at the cabinet top and be fixed with tie wraps to the holders in the cable inlets. To avoid the risk of objects falling into the cabinet, close the flexible inlets and tighten their screws after the installation. See Figure 3.

Battery cables should be selected according to local regulations concerning voltage drop, operational temperature and type of installation (open, covered, number of layers, parallel connection etc). What cable dimension to choose depends on the battery CB size, the tolerated cable voltage drop and the distance between the power system and the battery.
