Raritan Current Transformers (Optional)

A current transformer (CT) can detect the current of the circuit conductorthat passes through it and transmit the data to the Branch Circuit Monitor

where it is connected.

Raritan provides different CTs with different ratings. The CTs arecategorized into two types: mains CTs and branch circuit CTs. Both typesare split-core CTs.

Raritan mains CTs are for measuring main circuits rated up to 200A,250A or higher. Contact Raritan Technical Support for additionalinformation.

Raritan branch circuit CTs are for branch circuits rated up to 60A or100A.

The Raritan CT has two leads to connect to two CT terminals of anychannel on the Branch Circuit Monitor.

Warning: Do NOT use mains CTs to measure branch circuits or usebranch circuit CTs to measure mains circuits. This is because the mainsCTs must have built-in burden resistors but the branch circuit CTs mustnot have built-in burden resistors.

CT Dimensions

Sizes of different Raritan CTs are different.

Cascading the Branch Circuit Monitor v ia USB

Up to four (4) devices are supported as part of a daisy chain. This daisychain feature permits multiple Branch Circuit Monitor devices to becascaded using USB cables, sharing the Ethernet connectivity accordingly.Different models can be cascaded as long as they are running a supportedfirmware.

The first device in the chain is the master device and all subsequentdevices connected to it are slave devices. All devices in the chain areaccessible over an IP network, with the master Branch Circuit Monitoracting as a network bridge. Therefore, you can access individual devicesvia the Web, SNMP, SSH or Telnet interface no matter they are master orslave devices.

The USB-cascading configuration only supports wired networking so youmust make sure:

The master device has "wired" Ethernet connectivity.

None of the slave devices have a wired Ethernet connection. Eventhough you connect any slave device to the LAN through a networkcable, its wired Ethernet interface is automatically disabled.

None of the devices in the chain have wireless connectivity.

To cascade the Branch Circuit Monitor devices via USB:

1. Verify that the Branch Circuit Monitor devices to be cascaded arerunning the following firmware version by choosing Maintenance >Device Information in the web interface or using CLI's show bcmcommand. If not, upgrade these devices. See Updating the BranchCircuit Monitor Firmware (on page 217).

Branch Circuit Monitor: version 2.3.1 or later

2. Select one of the four devices as the master device and connect thisdevice to the LAN via a standard Category 5e/6 UTP cable.

3. Connect the USB-A port of the master device to the USB-B port of anadditional Branch Circuit Monitor via a USB cable. This additionaldevice is Slave 1.

Do not connect Slave 1 to the LAN.

4. Connect Slave 1's USB-A port to the USB-B port of an additionalBranch Circuit Monitor via a USB cable. The second additional deviceis Slave 2.


5. Connect Slave 2's USB-A port to the USB-B port of another BranchCircuit Monitor via a USB cable. The final additional device is Slave 3.

3. Repeat the above steps if there are additional SENSOR ports on yourBranch Circuit Monitor model.

If there are any Raritan air flow sensors attached, make sure that sensor

faces the source of the wind (such as a fan) in the appropriate orientationas indicated by the arrow on that sensor.

Contact Closure Sensors

Raritan's contact closure sensor (DPX-CC2-TR) can detect theopen-and-closed status of the connected detectors/switches.

This feature requires the integration of at least a discrete (on/off)detector/switch to work properly. The types of discrete detectors/switchesthat can be plugged into DPX-CC2-TR include those for:

Door open/closed detection

Door lock detection

Floor water detection

Smoke detection

Vibration detection

Raritan does NOT produce most of the above detectors/switches exceptfloor water sensors. When using third-party probes, you must test themwith Raritan's DPX-CC2-TR to ensure they work properly.

Important: Integration and testing for third-party detectors/switches

is the sole responsibi lity of the customer. Raritan cannot assumeany liability as a result of improper termination or failure (incidentalor consequential) of third-party detectors/switches that customersprovide and install. Failure to follow installation and configuration

instruct ions can result in false alarms or no alarms. Raritan makesno statement or claim that all third-party detectors/switches willwork with DPX-CC2-TR.

Raritan has changed the design of contact closure sensors and made newcontact closure sensors available for sale since the 4th quarter of 2012.Both old and new contact closure sensors function in the same manner,with the exception that only new contact closure sensors support Raritan'scable water sensors (DPX-WSC series) and floor-mounted water sensors(DPX-WSF). The latest PX firmware supports the use of either contactclosure sensor. See Old and New Contact Closure Sensors (on page38) for details.

Old and New Contact Closure Sensors

Raritan further improved the design of contact closure sensors andreleased a second version in the 4th quarter of 2012. Old and new contactclosure sensors are functionally identical. The major difference betweenthem is the mechanical design as described below.

The old sensor uses tiny buttons to secure or loosen wires of theconnected detectors/switches while the new sensor uses tiny screws.

The new sensor has a separate terminal module so that it is moreconvenient to connect or disconnect all connected detectors/switchesfrom the contact closure sensor.

Both old and new contact closure sensors share the same part number:

DPX-CC2-TR.

New type of DPX-CC2-TR is supported as of release 2.4 so make sureyou are running the firmware version 2.4 or later when using newDPX-CC2-TR. The latest Branch Circuit Monitor firmware continuouslysupports old type of DPX-CC2-TR.

For instructions on old contact closure sensors, see ConnectingDetectors/Switches to DPX-CC2-TR (on page 39).

For instructions on new contact closure sensors, see ConnectingDetectors/Switches to New DPX-CC2-TR (on page 40).

Connecting Detectors/Switches to DPX-CC2-TR

A DPX-CC2-TR unit provides two channels for connecting two discrete(on/off) detectors/switches. There are four spring-loaded termination

points on the body of DPX-CC2-TR: the two to the right are associatedwith one channel (as indicated by the LED number), and the two to the leftare associated with the other. You must plug discrete detectors/switchesinto these termination points.

To connect third-party or Raritan's d iscrete detectors/switches:

1. Strip the insulation around 12mm from the end of each wire of discretedetectors/switches.

2. Press and hold down the tiny rectangular buttons above thetermination points on the body of DPX-CC2-TR.

Note: Each button controls the spring of each corresponding
