• Ground Switching Relay K2 will also be energised, its Normally Opened (NO)
contacts will close and the Grounding Sockets of the two NeMA5-15r AC outlets
(10, Fig 3.1) will get disconnected from the metal chassis of the unit and get con

• The Inverter will switch ON and will provide 115VAC to the AC outlets.
• The Green LED “INVERTER” (8, Fig 3.1) will be switched ON
• The 2 cooling fans will switch ON for a short duration for around 6 seconds and
then switch off if the load connected to the AC outlets is less than 85W. The
fans are load controlled and will be switched oN automatically when the AC
load in the Inverter Mode is more than 85W
9. Wait for a few minutes and then Switch ON the AC side load(s). If more than one
load is used, switch oN one by one so that starting surges are staggered to prevent
overload shut down.
• If the AC load is more than 85W, the 2 cooling fans will switch ON
10. Under normal operation, the load(s) will be powered from the Inverter. In case any
abnormal operation is observed, refer to Troubleshooting Guide in Table 6.1 – Section 6.

Switching off the inverter
: Switch the Inverter ON/OFF Switch “INVERTER” (3, Fig 3.1)
to off position.
• 115VAC output will be switched OFF.
• The Green LED “INVERTER” (8, Fig 3.1) will NOT be switched OFF immediately
but will dim slowly and extinguish fully in around 1 minute

Please refer to Section 5.1.2 for description of this mode
1. Disconnect all AC side loads
2. Switch OFF the Inverter using the Inverter ON/OFF Switch “INVERTER” (3, Fig 3.1)
nOTe:
In this application of just a stand-alone battery charger, the Inverter is NoT
used and this switch will always be in off condition
3. Switch off the battery Charger using the battery Charger oN/off Switch “CHArGer”
(2, Fig 3.1)
4. Connect 12V batteries to the Battery Terminals (11, 12 in Fig 3.1)
5. As the Inverter ON/OFF Switch “INVERTER” (3, Fig 3.1) is in the OFF position, the fol

lowing will be seen:
• The Inverter will be in OFF condition
• The Green LED marked “INVERTER” (8, Fig 3.1) will be in OFF condition
• Transfer Relay K1 will be in de-energized condition and its normally closed (NC)
contacts will connect the Line Sockets of the AC outlets to the Line conductor of
the Grid AC input (if available)
• Ground Switching Relay K2 will also be in de-energised condition and, through
its Normally Closed (NC) contacts, the grounding sockets of the two NEMA5-15R
AC outlets (10, Fig 3.1) will be connected to the metal chassis of the unit
