1.2.2 Battery Safety
D ANGER
Do not connect the positive and negative poles of a battery or battery string
together. Otherwise, the battery may be short-circuited. Battery short circuits can
generate high instantaneous current and releases a large amount of energy, which
may cause battery leakage, smoke, ammable gas release, thermal runaway, re,
or explosion. To avoid battery short circuits, do not maintain batteries with power
on.
D ANGER
Do not expose batteries at high temperatures or around heat sources, such as
high-temperature sunlight, re sources, transformers, and heaters. Battery
overheating may cause leakage, smoke, ammable gas release, thermal runaway,
re, or explosion.
D ANGER
Protect batteries from mechanical vibration, falling, collision, punctures, and
strong impact. Otherwise, the batteries may be damaged or catch re.
UPS5000-E-(60 kVA-125 kVA)
User Manual (Integrated UPS 3.0) 1 Safety Information
Issue 04 (2022-12-30) Copyright © Huawei Digital Power Technologies Co., Ltd. 5

D ANGER
To avoid leakage, smoke, ammable gas release, thermal runaway, re, or
explosion, do not disassemble, alter, or damage batteries, for example, insert
sundries into batteries, squeeze batteries, or immerse batteries in water or other
liquids.
D ANGER
There is a risk of re or explosion if the model of the battery in use or used for
replacement is incorrect. Use a battery of the model recommended by the
manufacturer.
D ANGER
Battery electrolyte is toxic and volatile. Do not get contact with leaked liquids or
inhale gases in the case of battery leakage or abnormal odor. In such cases, stay
away from the battery and contact professionals immediately. Professionals must
wear safety goggles, rubber gloves, gas masks, and protective clothing, power o
the equipment, remove the battery, and contact technical engineers.
D ANGER
A battery is an enclosed system and will not release any gases under normal
operations. If a battery is improperly treated, for example, burnt, punctured,
squeezed, struck by a lightning, overcharged, or subject to other adverse
conditions that may cause battery thermal runaway, the battery may be damaged
or an abnormal chemical reaction may occur inside the battery, resulting in
electrolyte leakage or production of gases such as CO and H2. To prevent re or
device corrosion, ensure that ammable gas is properly exhausted.
D ANGER
The gas generated by a burning battery may irritate your eyes, skin, and throat.
Take protective measures promptly.
WARNING
Install batteries in a dry area. Do not install them under areas prone to water
leakage, such as air conditioner vents, ventilation vents, feeder windows of the
equipment room, or water pipes. Ensure that no liquid enters the equipment to
prevent faults or short circuits.
