power supply and contact the administrator.
D ANGER
● Do not expose the equipment to ammable or explosive gas or smoke. Do not
perform any operation on the equipment in such environments.
● During installation and maintenance, ensure that sundries do not enter the
UPS. Otherwise, equipment damage, load power derating, power failure, and
personal injury may occur.
If the mains voltage Vrms exceeds 320 V AC, the UPS may be damaged.
A UPS can be used to serve resistive-capacitive loads, resistive loads, and micro-
inductive loads. It is recommended that a UPS not be used for pure capacitive
loads, pure inductive loads, and half-wave rectication loads. A UPS does not
apply to regeneration loads.
Any operation on any electrical device in an environment that has inammable air
can cause extreme danger. Strictly obey the operating environmental requirements
specied in related user manuals when using or storing the device.
The UPS can be congured with a backfeed protection dry contact to work with
an external automatic circuit breaker, preventing the voltage from owing back to
input terminals over static bypass circuits. If the installation and maintenance
personnel do not need backfeed protection, paste labels on external mains and
bypass input switches, informing that the UPS is connected to a backfeed
protection card. Disconnect the backfeed protection card from the UPS before
operating the UPS.
Do not use the UPS in the following places:

1.7 Battery Safety
Basic Requirements
Before operating batteries, carefully read the safety precautions for battery
handling and master the correct battery connection methods.
D ANGER
● Do not expose batteries at high temperatures or around heat-generating
sources, such as sunlight, re sources, transformers, and heaters. Overheating
may cause battery explosion.
● Do not burn batteries. Otherwise, the batteries may explode.
● To avoid leakage, overheating, re, or explosions, do not disassemble, alter, or
damage batteries, for example, insert foreign objects into batteries or immerse
batteries in water or other liquids.
● Wear goggles, rubber gloves, and protective clothing to avoid damage caused
by electrolyte in the case of electrolyte overow. If a battery overows,
protect the skin or eyes from the leaking liquid. If the skin or eyes come in
contact with the leaking liquid, wash it immediately with clean water and go
to the hospital for medical treatment.
● Use dedicated insulated tools.
● Move batteries in the correct direction. Do not place a battery upside down or
tilt it.
● Keep the battery loop disconnected during installation and maintenance.
● Use batteries of specied models. Using batteries of other models may
damage the batteries.
● Dispose of waste batteries in accordance with local laws and regulations. Do
not dispose of batteries as household waste. If a battery is disposed of
improperly, it may explode.
