1.5 UPS Safety

During installation, operation, and maintenance, prevent foreign matter from
entering the UPS. Otherwise, equipment damage, load power derating, power
failure, or personal injury may occur.
The category 2 (C2) UPS may cause radio interference when used in a residential
environment. Additional measures may be needed to prevent the interference.
The category 3 (C3) UPS is intended for commercial and industrial application in
the second class environment. Installation restrictions or additional measures may
be needed to prevent disturbances.

The UPS is used for commercial and industrial purposes only. It cannot be
used as a power supply for life support devices.
For power supply systems that are critical to significant economic interests or
public order, such as the national computing center, military command
system, emergency command center, railway signal system and control center,
civil aviation and air traffic control center, airport command center, financial
clearing center, and transaction center, the Tier 4 or 3 power architecture
specified in TIA-942 must be used. That is, two power supplies must be used
to supply power to loads.
If the root mean square (RMS) 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.
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.
The upstream power distribution of the UPS should comply with IEC
60364-4-41.
