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 device 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 device.
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.
