1.2.2 Battery Safety

Do not connect the positive and negative poles of a battery or battery string
together. Otherwise, the battery may be short-circuited. Battery short circuits can
generate high instantaneous current and releases a large amount of energy, which
may cause battery leakage, smoke, flammable gas release, thermal runaway, fire,
or explosion. To avoid battery short circuits, do not maintain batteries with power
on.

must be used. That is, two power supplies must be used to supply power to
loads.
The UPS operating environment must meet the requirements for the climate
indicator, mechanically active substance indicator, and chemically active
substance indicator in ETSI EN 300 019-1 class 3.6.
The UPS must not be located in non-confined environments near the ocean
(0–3.7 km) or indoor or semi-indoor environments where the temperature
and humidity are not controllable, such as simple equipment rooms, civil
houses, garages, corridors, and direct ventilation cabinets near the ocean; or
houses with only roofs, railway station platforms, gymnasiums, and
aquariums.
The UPS should be powered on as soon as possible after it is unpacked.
The UPS can be used to serve resistive-capacitive loads, resistive loads, and
micro-inductive loads. It is recommended that the UPS not be used for pure
capacitive loads, pure inductive loads, or half-wave rectification loads. The
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, attach 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 meet the requirements of
protection against electric shock specified in IEC 60364-4-41.
A circuit breaker equipped with a residual current device (RCD) is not
recommended.
If the root mean square (RMS) of a phase voltage of the utility power exceeds
320 V AC, the UPS may be damaged.
To ensure power supply to loads during UPS upgrade, set the output to
maintenance bypass mode. To avoid power failure or load damage, ensure
that the bypass input is within the specified power supply range.
Exercise caution when manually shutting down the UPS inverter for
transferring to bypass mode, or when adjusting the UPS output voltage level
or output frequency. Doing so may affect the power supply to equipment.
