Do not connect the cables between the UPS battery terminals and the batteries before getting the
approval from the commissioning engineer.
During cables connection between the battery terminals and the circuit breaker, always connect the
circuit breaker end of the cable first.
Be sure to connect the positive/negative terminals of the batteries to those of the circuit breakers
and those of the circuit breakers to those of the UPS respectively with reference to the markings of
positive/negative terminals.
Reverse connection of battery polarities will result in explosion, fire accident, the damage of
batteries and UPS, and human injury.
The battery connection terminals shall not subject to any external force, such as the pulling force or
twisting force of the cable. Otherwise, the internal connection of the battery may be damaged, and
in severe case, the battery may catch fire.
Do not connect power until the total voltage of the battery string is verified through measurement.
Do not connect any conductor between the positive and negative terminals of the batteries.
Do not close the battery circuit breakers before getting the approval from the commissioning
engineer.
