1. Check and confirm that the UPS power distribution mode is correct, that the power cables and signal
cables are connected correctly, and there are no short circuits.
2. Check that the batteries have been installed properly, the cables have been connected correctly, and
that the positive and negative battery poles are correct.

and the authorized service engineer has completed the commissioning tests and shut down the
external power input switches.
