● The category C2 UPS may cause radio interference when used in a residential
environment. Additional measures may be needed to prevent the interference.
● The category C3 UPS product is intended for commercial and industrial
application in the second class environment. Installation restrictions or
additional measures may be needed to prevent disturbances.
● After unpacking the UPS, you are advised to power it on as soon as possible. If
the UPS is not in operation, take appropriate measures to prevent moisture,
dust, and foreign matter from entering the UPS.
● After unpacking batteries, you are advised to connect the battery supply as
soon as possible. Store unused batteries properly and charge them in time if
they are stored for more than 90 days. Otherwise, the battery lifespan may be
affected.
● Install the UPS in an area far away from liquids. Do not install it under areas
prone to water leakage, such as air conditioner vents, ventilation vents, or
feeder windows of the equipment room. Ensure that no liquid enters the UPS
to prevent short circuits and that there is no condensation inside the equipment
or equipment room.
● If any liquid is detected inside the equipment, disconnect the power supply
immediately and contact the administrator.

● Do not expose the equipment to flammable 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 root mean square of the mains voltage 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 rectification loads. A UPS does not
apply to regeneration loads.
Any operation on any electrical equipment in an environment that has
inflammable air can cause extreme danger. Strictly obey the operating
environmental requirements specified in related user manuals when using or
storing the equipment.
The UPS can be configured with a backfeed protection dry contact to work with
an external automatic circuit breaker, preventing the voltage from flowing 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.
