Do not use a damaged battery (such as damage caused when a battery is dropped, bumped,
bulged, or dented on the enclosure), because the damage may cause electrolyte leakage or
flammable gas release. In the case of electrolyte leakage or structural deformation, contact
the installer or professional O&M personnel immediately to remove or replace the battery. Do
not store the damaged battery near other devices or flammable materials and keep it away
from non-professionals.
Before working on a battery, ensure that there is no irritant or scorched smell around the
battery.
When installing batteries, do not place installation tools, metal parts, or sundries on the batter-
ies. After the installation is complete, clean up the objects on the batteries and the surrounding
area.
Do not install battery packs on rainy, snowy, or foggy days. Otherwise, the battery packs may
be corroded by moisture or rain.
If batteries are exposed to water accidentally, do not install them. Instead, transport the batter-
ies to a safe isolation point and dispose of them in a timely manner.
Before installing battery packs, check whether they are abnormal. A battery pack is deemed
abnormal when any of the following symptoms occurs:
– The enclosure of the battery pack is obviously deformed or damaged.
– The voltage between the positive and negative electrodes of the battery pack is far below
the specified range.
Check whether the positive and negative battery terminals are grounded unexpectedly. If so,
disconnect the battery terminals from the ground.
Do not perform welding or grinding work around batteries to prevent fire caused by electric
sparks or arcs.
If batteries are left unused for a long period of time, store and charge them according to the
battery requirements.
Do not charge or discharge batteries by using a device that does not comply with local laws
and regulations.
Keep the battery loop disconnected during installation and maintenance.
Monitor damaged batteries during storage for signs of smoke, flame electrolyte leakage, or
heat.
If a battery is faulty, its surface temperature may be high. Do not touch the battery to avoid
scalds.
Do not stand on, lean on, or sit on the top of the equipment.
In backup power scenarios, do not use the batteries for the following situations:
– Medical devices substantially important to human life
– Control equipment such as trains and elevators, as this may cause personal injury
– Computer systems of social and public importance
– Locations near medical devices
– Other devices similar to those described above
Short-Circuit Protection
When installing and maintaining batteries, wrap the exposed cable terminals on the batteries
with insulation tape.
