TP48200A-HX09A3 & TP48200A-HX09A4 &


TBC300A-TCA2




6

Do not use unsealed lead acid storage batteries. Lead acid storage batteries must be placed

horizontally and stably to prevent the batteries from releasing flammable gas, which may

cause fire or erode the device.

Lead acid storage batteries in use emit flammable gas. Therefore, ventilation and

fireproofing measures must be taken at the sites where lead acid storage batteries are used.

Battery Temperature

If a battery overheats, the battery may be deformed or damaged, and the electrolyte may

overflow.

When the temperature of the battery is higher than 60°C, check the battery for electrolyte

overflow. If the electrolyte overflows, absorb and counteract the electrolyte immediately.

Battery Leakage

If the electrolyte overflows, absorb and counteract the electrolyte immediately.

When moving or handling a battery whose electrolyte leaks, note that the leaking electrolyte

may hurt human bodies. When you find the electrolyte leaks, use the following substances to

counteract and absorb the leaking electrolyte:

Sodium bicarbonate (baking soda): NaHCO3

Sodium carbonate (soda): Na2CO3

Select a substance to counteract and absorb the leaking electrolyte according to the

instructions of the battery manufacturer.

1.1.5 Working at Heights

Using Ladders

Checking a Ladder Before using a ladder, check whether the ladder is damaged. Only the ladder in good

condition can be used.

Before using a ladder, you should know the maximum weight capacity of the ladder.

Avoid overweighting the ladder.

Placing a Ladder

The recommended gradient of ladders is 75 degrees. You can measure the gradient of the

ladder with a right angle or your arms. When using a ladder, ensure that the wider feet of the

ladder are downward, or take protection measures for the ladder feet to prevent the ladder

from sliding. Ensure that the ladder is placed securely.

Climbing Up a Ladder

When climbing up a ladder, note the following:

Ensure that the center of gravity of your body does not deviate from the edges of the two

long sides.

To minimize the risk of falling, hold your balance on the ladder before any operation.

Do not climb higher than the fourth rung of the ladder (counted from up to down).

If you want to climb up a roof, ensure that the ladder top is at least one meter higher than

the roof.

1.1.6 Mechanical Safety

Drilling Holes

Do not drill the cabinet at will. Drilling holes without complying with the requirements affects

the electromagnetic shielding performance of the cabinet and damages the cables inside the

cabinet. In addition, if the scraps caused by drilling enter the cabinet, the printed circuit

boards (PCBs) may be short circuited.

Before you drill a hole in the cabinet, wear insulated gloves and remove the internal

cables from the cabinet.

Wear an eye protector when drilling holes. This is to prevent your eyes from being

injured by the splashing metal scraps.

Ensure that the scraps caused by drilling do not enter the cabinet.

Drilling holes without complying with the requirements affects the electromagnetic

shielding performance of the cabinet.

After drilling, clean the metal scraps immediately.

TP48200A-HX09A3 & TP48200A-HX09A4 &


TBC300A-TCA2




10

If the "high electrical leakage" tag is present on the power terminal of the device, you must

ground the device before powering it on.

1.2.2 Electrostatic Discharge

The static electricity generated by human bodies may damage the electrostatic-sensitive

components on boards, for example, the large-scale integrated (LSI) circuits.

Human body movement, friction between human bodies and clothes, friction between shoes

and floors, or handling of plastic articles causes static electromagnetic fields on human bodies.

These static electromagnetic fields cannot be eliminated until the static is discharged.

To prevent electrostatic-sensitive components from being damaged by the static on human

bodies, you must wear a well-grounded electrostatic discharge (ESD) wrist strap when

touching the device or handling boards or application-specific integrated circuits (ASICs).

1.2.3 Laying Out Cables

When the temperature is very low, violent strike or vibration may damage the cable sheathing.

To ensure safety, comply with the following requirements:

Cables can be laid or installed only when the temperature is higher than 0°C.

Before laying out cables which have been stored in a temperature lower than 0°C, move

the cables to an environment of the ambient temperature and store them at the ambient

temperature for at least 24 hours.

Handle cables with caution, especially at a low temperature. Do not drop the cables

directly from the vehicle.

1.2.4 Rectifier

When a rectifier is running, the temperature around the air exhaust vent at the rear is

high. Do not touch the vent or cover the vent with cables or other objects.

To prevent electric shocks, do not put your hands into rectifier slots.

2.4 Working Principles

Figure 2-7 shows the conceptual diagram. AC power enters rectifiers through the AC power

distribution unit (PDU). The rectifiers convert the AC power input into -48 V DC power

output, which is directed by the DC PDU to DC loads along different routes.

When the AC power is normal, rectifiers power DC loads and charge batteries. When the AC

power is absent, rectifiers stop working and batteries start to power loads. After the AC power

resumes, rectifiers power DC loads and charge batteries again.

The SMU monitors the operating status of each component in the power system in real time

and performs appropriate intelligent control. When detecting a fault, the SMU generates an

alarm. The SMU monitors and regulates the temperature control unit based on the temperature

measured by the temperature sensor to ensure the normal operating temperature for the

cabinet.

3.6 Temperature Control Unit (for the TP48200A-HX09A3 and TP48200A-HX09A4)

3.6.1 Heat Exchange

The equipment compartment of the power cabinet adopts heat exchanging to cool the

equipment compartment, in which heat is exchanged through internal circulation and external

circulation.

Internal circulation: hot air in the equipment compartment is drawn by the internal fan into the

heat exchanger, passes through the heat exchanging core from top to bottom, then releases

heat to change to cold air, and finally returns to the equipment compartment through the

internal air exhaust vent under the heat exchanger.

External circulation: natural air outside the equipment compartment is drawn by the external

fan into the heat exchanger via the equipment compartment, passes through the heat

exchanging core from bottom to top, then absorbs heat to change to hot air, and finally flows

out of the equipment compartment from the external air exhaust vent.

Figure 3-20 shows the heat exchange working principles.

TEC Working Principle

The TEC cools and heats air through internal and external circulation. Table 3-13 describes

how the TEC works. Figure 3-27 shows the TEC airflow directions.

Table 3-13 TEC working principles

Function Working Principle

Cooling The TCUA control box controls the refrigeration chip in the TEC

module to cool the internal circulating air. The internal circulation fan

draws the air inside the battery compartment into the internal circulation

heat sink. The internal circulation heat sink cools the air and then returns

the cooled air to the battery compartment through the air exhaust vents.

Meantime, the external circulation fan draws natural air into the external

circulation heat sink to accelerate the airflow. The air absorbs the heat

TP48200A-HX09A3 & TP48200A-HX09A4 &


TBC300A-TCA2




44

Function Working Principle

from the external circulation heat sink and returns to the external

environment through the air exhaust vents on the external circulation

heat sink. The heat exchange between the internal and external

environment is implemented so far.

Heating The TCUA control box controls the refrigeration chip in the TEC

module to heat the internal circulating air. The internal circulation fan

draws the air inside the battery compartment into the internal circulation

heat sink. The internal circulation heat sink heats the air and then returns

the heated air to the battery compartment through the air exhaust vents.

Meantime, the external circulation fan operates according to control

logic and draws natural air into the external circulation heat sink. The air

gives out heat and returns to the external environment through the air

exhaust vents on the external circulation heat sink.
