1. Check that battery cables are
correctly connected.
2. Check that the battery terminal
voltage is normal.
3. Check that the battery fuse in the

1. Check whether battery parameters
are correctly set.
2. If they are correctly set, certain
batteries may be faulty.
3. Check whether the battery neutral
wire is correctly connected.
1. If the low battery voltage alarm is
generated in battery mode, check
whether the mains voltage
recovers. If yes, charge batteries
immediately.
2. Check whether the battery neutral
wire is correctly connected.
3. If this alarm is generated in normal
mode, check whether the battery
switch is ON. If yes, the charger
may be faulty. Replace the related
power unit.
1. Check whether the positive and
negative terminals of the battery
string are grounded or have
sufficient resistance to the ground.
2. Check whether the battery
grounding failure detector is faulty
by replacing it with a new one.
3. If no battery grounding failure
detector is available, check on the
dry contact board whether the
battery grounding failure detector
is enabled. If yes, disable it and
check whether the alarm is cleared.
If the alarm persists, the dry
contact board may be faulty.
Replace the board.
