User Manual 1 Safety Precautions



1

1 Safety Precautions

1.1 General Safety Precautions Ensure that the product is used in environments that meet its design specifications to

avoid damaging components and voiding the warranty.

Ensure that only trained and qualified personnel install, operate, and maintain Huawei

equipment.

Comply with local laws and regulations. The safety instructions in this document are

only supplements to local laws and regulations.

Do not operate the device or cables during thunderstorms.

Remove metal objects such as watches, bracelets, and rings when using the product.

Use insulated tools on the product.

Follow specified procedures during installation and maintenance.

Measure contact point voltage with an electric meter before touching a conductor surface

or terminal. Ensure that the contact point has no voltage or it is within the specified

range.

Note that the load may power off during maintenance or fault location if the power

system is not connected to a battery or if battery capacity is insufficient.

Store cables for at least 24 hours at room temperature before laying out them if they were

previously stored at sub-0ºC.

Routinely check installed equipment and perform maintenance according to the user

manual; replace faulty components quickly to ensure that the device works properly.

1.2 Electrical Safety

Grounding Requirements

When installing a device, install the ground cable first. When removing a device, remove

the ground cable last.

Before operating a device, ensure that the device is properly grounded.

AC and DC Operation Requirements

MTS9511A-GX2002




2

The power system is powered by high-voltage power sources. Direct or indirect contact

(through damp objects) with high-voltage power sources may result in serious danger.

Non-standard and improper operations may result in fire and electric shocks.

Before electrical connections, turn off the upstream protection switch for the device.

Before connecting the AC power supply, ensure that electrical connections are complete.

Before you connect cables to loads or battery cables, check cable and terminal polarities,

preventing reverse connections.

ESD Requirements

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

human bodies, wear a well-grounded ESD wrist strap or gloves when touching circuit

boards.

When holding a board, hold its edge without components. Do not touch chips.

Removed boards must be packaged with ESD packaging materials before storage and

transportation.

Liquid Prevention Requirements

Place this product far away from areas with liquid. Do not place the product under

positions prone to leakage, such as air conditioner vents, ventilation vents, and feeder

windows of the equipment room. Prevent liquid from entering the inside of the device to

avoid short circuits, and ensure that there is no condensation inside the equipment room

or device.

If detecting any liquid inside the device, immediately disconnect the power supply and

contact the administrator.

1.3 Battery Safety

Before installing, operating, and maintaining batteries, read the instructions provided by the

battery vendor. The safety precautions in this document are for special attention. For more

safety precautions, see the instructions provided by the battery vendor.

Basic Requirements

Before installation and maintenance, wear goggles, rubber gloves, and protective clothes

to prevent injury caused by electrolyte overflow.

When handling a battery, ensure that its electrodes are upward. Leaning or reversing

batteries is prohibited.

Keep the battery loop disconnected during installation and maintenance.

Secure battery cables to a torque specified in battery documentation. Loose connections

will result in excessive voltage drop or cause batteries to burn out when the current is

large.

MTS9511A-GX2002




3

Preventing Battery Short Circuit

Short circuits will generate high transient currents and release a great deal of energy, which

may cause personal injury.

If conditions permit, disconnect the batteries in use before performing any other operations.

Preventing Flammable Gas

Do not use unsealed lead-acid batteries.

Place and secure lead-acid batteries horizontally to prevent device inflammation or

corrosion due to flammable gas emitted from batteries.

Lead-acid batteries in use emit flammable gas. Therefore, store the batteries in a place with

good ventilation, and take measures against fire.

Preventing Battery Leakage

High temperatures may result in battery distortion, damage, and electrolyte overflow.

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

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

or handling a battery whose electrolyte leaks, exercise caution because the leaking electrolyte

may hurt human bodies. When you find electrolyte leaks, use sodium bicarbonate (NaHCO3)

or sodium carbonate (Na2CO3) to counteract and absorb the leaking electrolyte.

Preventing Battery Overdischarge

After you connect batteries, ensure that the battery fuse is disconnected or the circuit breaker

is OFF before powering on the power system. This prevents battery overdischarge, which

damages batteries.

1.4 Cable Layout When cables are used in a high temperature environment, the insulation layer may age

and be damaged. Ensure that a sufficient distance exists between the cables and the DC

busbar, shunt, and fuse.

MTS9511A-GX2002




4

Signal cables must be bound separately from strong-current cables and high-voltage

cables.

Cables prepared by the customer must have the fire resistance capability.

Cables must not pass behind the air exhaust vents of rectifiers in the cabinet.

1.5 Mechanical Safety

Hoisting Devices

Do not walk under cantilevers or raised objects.

Only trained and qualified personnel are allowed to perform hoisting operations.

Before hoisting objects, check that all hoisting tools are available and in good condition.

Before hoisting objects, ensure that hoisting tools are firmly fixed onto a weight-bearing

object or wall.

Ensure that the angle formed by two cables is less than 90 degrees.

Using a Ladder

Use only ladders that are in good condition. Find out and do not exceed the maximum

weight capacity.

The recommended angle for a ladder against another object is 75 degrees. Measure the

gradient with a right angle or your arms, as shown in Figure 1-1. Ensure that the wider

end of the frame is at the bottom, the base cannot slide, and that the ladder is securely

positioned.

Figure 1-1 Correct angle for ladders

When climbing a ladder:

− Ensure that your body's center of gravity does not shift outside the legs of the ladder.

− To minimize the risk of falling, steady your balance on the ladder before performing

any operation.

MTS9511A-GX2002




5

− Do not climb higher than the fourth rung from the top.

To climb onto a roof, ensure that the ladder top is at least one meter higher than the roofline,

as shown in Figure 1-2.

Figure 1-2 One meter higher than the roofline

Drilling Holes

Do not drill holes into a cabinet without permission. Non-standard drilling may affect the

electromagnetic shielding of the cabinet and damage interior cables. Metal shards generated

during drilling may short-circuit circuit boards if they get into the cabinet.

Before drilling holes into a cabinet, remove interior cables.

Wear goggles and protective gloves when drilling holes.

After drilling, clean up metal shards immediately.

Moving Heavy Objects

Be cautious to prevent injury when moving heavy objects.

Wear protective gloves when moving heavy objects.

normal. Red indicates the AC SPD is faulty.

4.2.2 Identifying Circuit Breaker Faults

The following lists main circuit breaker faults:

The circuit breaker cannot be switched to ON/OFF after the short circuit fault for its end

circuit is rectified.

When the circuit breaker is switched to ON and its input voltage is normal, the voltage

between the two ends of the circuit breaker exceeds 1 V.

The input voltage is normal, but the resistance between both ends of the circuit breaker is

less than 1 kΩ when the circuit breaker is OFF.

4.2.3 Identifying Rectifier Faults

If any of the following occurs, the rectifier is faulty:

MTS9511A-GX2002




30

The AC input and slot connector are normal, but the Fault indicator (red) is steady on or

all indicators are off.

The slot connector and SMU are normal, but the Alarm indicator (yellow) still blinks

after the rectifier is reseated.

The AC input and SMU are normal, but the SMU cannot control the rectifier.

4.2.4 Identifying SMU Faults

The following are the main symptoms of SMU faults:

The DC output is normal while the green indicator on the SMU is off.

The SMU breaks down or cannot be started. Its LCD has abnormal display or buttons

cannot be operated.

With the alarm reporting enabled, the SMU does not report alarms when the power

system is faulty.

The SMU reports an alarm while the power system does not experience the fault.

The SMU fails to communicate with the connected lower-level devices while the

communications cables are correctly connected.

Communication between the SMU and all rectifiers fails while both the rectifiers and the

communications cables are normal.

The SMU cannot monitor AC or DC power distribution when communications cables are

intact and AC and DC power distribution is normal.

Parameters cannot be set or running information cannot be viewed on the SMU.

4.3 Replacing Components

Ensure that loads are supplied with power when replacing major components. For example,

keep the switches for primary loads in the ON position, and do not turn off the battery

switch and AC input switch at the same time.

Seek the customer's prior consent if load disconnection is required.

Rectifiers and the SMU are hot-swappable.
