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
User Manual 1 Safety Precautions
Issue 01 (2015-07-05) Huawei Proprietary and Confidential

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.

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.

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.

− 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.
