Expected Result
Conduct a shallow
discharge test when the
UPS is backed up to verify
that the batteries can
discharge normally.
Expected Result
When the UPS is backed up,
discharge a battery to the
undervoltage alarm threshold,
to refresh the capacity of the
battery.
1. Each battery terminal is
connected reliably. (When
battery strings are
powered off, check the
reliability of each terminal
in the order from positive
terminals to negative
terminals.)
2. The tightening torque of
each battery screw meets
the requirements of the
battery manufacturer. (A
torque wrench is used for
checking the torque. After
checking that the battery
screws meet the
requirements, mark the
screws for later check.)
