6. Plug the AC input cord to the 120 VAC, 15A GfCI protected Grid AC outlet.
7.
Switching on the Battery charger:
Switch the battery Charger oN/off Switch
“CHARGER” (2, Fig 3.1) to ON position.
8. The battery Charger will switch oN and start charging the batteries.
9. The Green LED “CHARGER” (7, Fig 3.1) will be switched ON
10. The 2 cooling fans will switch oN for a short duration of around 6 sec and then
switch off. These fans are load controlled and will switch oN automatically when
the charging current is more than 3 ± 1A
11.
Switching off the Battery charger:
Switch the battery Charger oN/off Switch
“CHARGER” (2, Fig 3.1) to OFF position.
12. The battery Charger will switch off and stop charging the batteries.

Protections, Monitoring
& Troubleshooting
6.1 protectionS anD monitorinG in inverter moDe
note: please refer to table 6.1 for status of monitoring LeDs and Buzzer for various
protections / operational conditions explained below.
6.1.1 Load controlled cooling fan
Cooling is carried out by convection and by forced air circulation by 2 load-controlled
fans. The fans will normally be off and will be switched oN automatically as follows:
• Inverter supplying AC load(s): When load(s) ≥ 85W
• Battery Charging/AC Pass Through Mode: When charging current ≥ 3A ± 1A
This will reduce energy consumption by the fan and will increase overall efficiency.
6.1.2 over temperature protection
As explained above, the unit is cooled by load-controlled fans - will switch ON at load
> 85W or when charging current is > 3A ± 1A. In case the fan(s) fail or if the cooling is
inadequate due to higher ambient temperature or restricted airflow, the temperature of
hot spot inside the Inverter will exceed the safe temperature threshold of 88
o
C to 115
o
C
and the Inverter will automatically shut down. Yellow LED "
INPUT fAULT
" (6, Fig 3.1) will
be lighted and Green LeD "INVerTer
" (8, Fig 3.1) will switch OFF. The Inverter will reset
automatically when the hot spot cools down by 10
o
- 15
o
C below the above threshold.
