Installation and Operation
e. Plug the NEMA5-15P plug (2, Fig 3.1) of the Inverter power cord (1, Fig 3.1) to
the output of the Inverter (Fig 5.4). As pointed out earlier, in case the Inverter
capacity is >1800 VA & up to 3600 VA, appropriate connection arrangement using
AWG#10/3 wiring will have to be used. Please ensure that the Inverter is switched
OFF and the battery input connection to the Inverter is disconnected.
f.
Plug the external Battery Charger / Converter to one of the receptacles of the
NEMA-20R Duplex receptacle (3, Fig 3.1; Fig 5.4). Please ensure that the AC input
current of the Battery Charger is less than 16A continuous as the receptacle is
internally fused at 20A max. In case the current drawn by the external Battery
Charger is > 16A continuous, it should be wired to a separate circuit connected to
the NC contact terminals T5 and T6 through a fuse applicable to the input current
of the Battery Charger.
g.
In case the Transfer Switch is being used in an RV application, the built-in
Converter of the RV should be disconnected from the AC Breaker Panel (Fig 5.4).
This is necessary because when the panel is fed by the Inverter and if the Converter
is not disconnected from the panel, it will result in a battery to Inverter to
Converter to battery loop that will quickly drain the batteries. In case the external
Battery Charger is not being used, the Converter may be re-wired to the NEMA5-
20R Duplex receptacle (3. Fig 3.1). As these receptacles are connected to the NC
contact terminals T5 and T6, the Converter will always be powered from the Grid /
Shore Power Cord / the Generator.
h. Testing of Operation:
(i) Switch OFF both the Grid and the Inverter
(ii)
Switch ON the AC input power from the Inverter. As the time delay has been
disabled (As explained at (b) above), relay coil will energize as soon as AC
input from the Inverter is available. The Green LED 1 will light up indicating
that the relay has energized. If the Main Panel circuit breakers are switched
ON, the AC loads will be powered by the Inverter. The external Battery
Charger / Converter will be OFF.
(iii) Switch ON the Grid. The Grid will be in standby condition.
(iv) Switch OFF the AC input power from the Inverter. The relay will immediately
de-energize and the AC loads will be transferred to the Grid.
