Installation and Operation
a. As Generator is not being used in this configuration, disable the Time Delay Circuit
by changing the position of DIP Switch SW1 from OFF to ON position (Switch is
factory preset in OFF condition).
b. Use AWG#10/3 (30A) cable to connect AC input power from Grid / Shore Power
Cord (RV). A 3/4" cable clamp (4, Fig 3.1) has been provided for cable entry. More
3/4" / 1" knock outs have also be provided for cable entry from other sides and may
be used Connect the cable as follows:
-
The Black wire to the black pigtail connected to the NO, Line “L1” contact
terminal T3. Use the twist-on type of Wire Nut provided for splicing the ends.
-
The White wire to the white pigtail connected to the NO, Neutral “N1” contact
terminal T4. Use the twist-on type of Wire Nut provided for splicing the ends.
-
The Green or bare grounding wire to one of the spare Grounding Studs marked:
-
Use an appropriate insulated ring or spade lug for making this connection
c. Use AWG#10/3 cable to connect the AC output to the Main Breaker Panel by using
a convenient knockout / cable clamp (3/4” or 1”) for cable entry. Cable clamp has
not been provided for this connection and has to be provided by the user. Connect
the 3 wires as follows (Fig 5.3):
-
The Black wire to the common Line “L” contact terminal T1 and the White wire
to the common Neutral “N” contact terminal T2. Use appropriate insulated ring
/ fork lugs at the bare end of the wires for firm contact.
-
The Green or bare grounding wire to one of the spare grounding studs marked:
-
Use an appropriate ring or spade lug for making this connection.
d. Plug the NEMA5-15 plug (2, Fig 3.1) of the Inverter power cord (1, Fig 3.1) to
the output of the Inverter (Fig 5.3). 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.
e. Plug the external Battery Charger / Converter to one of the receptacles of the
NEMA-20R Duplex receptacle (3, Fig 3.1; Fig 5.3).
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 NO contact terminals T3 and T4 through a fuse applicable to the input current
of the Battery Charger.
f. 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 5.3).
This is necessary because when the Grid / Shore Power Cord / the Generator fails
or is disconnected, the panel will be 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 NO contact
terminals T3 and T4, the Converter will always be powered from the Grid / Shore
Power Cord / the Generator.
