note: please refer to table 6.2 for status of monitoring LeDs for various protections /
operational conditions explained below:
In this mode, Grid AC Power is available, is being passed through to the Load(s) and Bat
-
tery Charger is charging the batteries:
6.2.1 overload / Short circuit protection in ac Load(s)
15A Breaker (4, Fig 3.1) in the AC Input Circuit of the unit provides protection against
overload and short circuit in the AC loads when the unit is in Grid AC Power Pass
Through Mode.
6.2.2 overload / Short circuit protection in ac input circuit of
Battery charger
5A, 250V fuse (5, Fig 3.1) is provided in the AC input circuit of the Battery Charger to
protect the battery Charger against overload and short circuit.
6.2.3 protection against Ground fault in ac Loads
AC input to the unit is required to be fed from 15A GfCI protected AC outlet of Grid AC
Power. In case of Ground fault in the AC load(s), the GFCI in the 15A GFCI protected AC
outlet of Grid AC Power will trip.

• Charging is normal
• AC output voltage is
not available
Unit is in Grid Pass
Through Mode but the
15A AC Input breaker on
the unit (4, Fig 3.1) has
tripped due to continu-

• Check and remove
short circuit on the
AC load side
• Reset the 15A
breaker on the unit
