• Ground Switching Relay K2 will also be energised, its Normally Opened (NO)
contacts will close and the Grounding Sockets of the two AC outlets will get
disconnected from the metal chassis of the unit and get connected to the
internal GfCI circuitry
• The Battery Charger will switch OFF. Green LED “CHARGER” (7, Fig 3.1) will also
be switched off
• The battery will start discharging at current = Power of AC load(s) in Watts ÷ 10
5.3.2 Switching off procedure:
1. Switch OFF the Charger using ON/OFF Switch marked “Charger” (2, Fig 3.1)
2. Switch OFF the load(s)
3. Switch OFF the Inverter using ON/OFF Switch marked “Inverter” (3, Fig 3.1)
4. Disconnect AC input Power Cord
5.4 connection anD operation aS StanD-aLone inverter
Please refer to Section 5.1.3 for description of this mode
1. As battery charging / Grid AC pass-through is not used in this mode, do not connect
the AC input cord to Grid AC outlet
2. Make sure that the maximum single / combined AC side load is less than 1500W.
Please refer to the Sizing Chart at Table 5.1 for guidance
3. Disconnect all AC side loads
4. Switch OFF the Inverter using the Inverter ON/OFF Switch “INVERTER” (3, Fig 3.1)
5. Switch off the battery Charger using the battery Charger oN/off Switch “CHArG-
ER” (2, Fig 3.1)
6. Connect 12V batteries to the Battery Terminals (11, 12 in Fig 3.1)
7. 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 “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 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 AC outlets
will be connected to the metal chassis of the unit
8.
Switching on the inverter
: Switch the Inverter ON/OFF Switch “INVERTER” (3, Fig
3.1) to oN position
• Transfer Relay K1 will be energized, its Normally Open (NO) contacts will close and
will transfer the connection of the Line Sockets of the AC outlets from the Line
conductor of the Grid input to the Line conductor of the output of the Inverter
