INSTALLATION
a. Feed the 3 core cable from the electric utility / shore power cord / the generator through the
¾” cable clamp that has been provided (4, Fig1). Connect the three cores as follows (Fig 4):
-
The black core to the black piece of wire connected to the NO, Line “L1” contact terminal
T3. Use the twist-on type of wire nut provided for splicing the ends.
-
The white core to the white piece of wire connected to the NO, Neutral “N1” contact
terminal T4. Use the twist-on type of wire nut provided for splicing the ends.
-
The green grounding core to one of the spare grounding studs. Use an appropriate
insulated ring or spade lug for making this connection
b. Feed the 3 core cable for output to the main breaker panel by using a convenient knockout
/ cable clamp (3/4” or 1”) for the cable entry. Cable clamp has not been provided for this
connection and has to be provided by the user. Connect the 3 cores as follows (Fig 4):
-
The black core to the common Line “L” contact terminal T1 and the white core to the
common Neutral “N” contact terminal T2. Use appropriate insulated ring / fork lugs at the
bare end of the wires for fi rm contact.
-
The green grounding core to one of the spare grounding studs. Use an appropriate ring
or spade lug for making this connection
c. Plug the NEMA5-15 plug (2, Fig 1) of the inverter power cord (1, Fig 1) to the output of
the inverter (Fig 4).
Please ensure that the inverter is switched off and the battery input
connection to the inverter is disconnected.
d. Plug the external battery charger to one of the receptacles of the dual NEMA5-15R receptacle
(3, Fig 1; Fig 4).
Please ensure that the AC input current of the battery charger is less than 12
A continuous as the receptacle is internally fused at 15 A max. In case the current drawn by
the external battery charger is > 12 A continuous, the charger 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 charger.
e. 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 4).
This is necessary because when the
electric utility / shore power cord / the generator fails / is removed, 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 one of the
dual NEMA5-15R receptacles (3. Fig 1). As these receptacles are connected to the NO contact
terminals T3 and T4, the converter will always be powered from the electric utility / shore
power cord / the generator.
In case the current drawn by the converter is > 12 A continuous,
the converter 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 converter.
f. In case the primary power source is electric utility / shore power cord, the time delay of 20 sec
has to be disabled by setting the internal DIP Switch SW1 (Figs 2, 4) to ON position. In case the
primary source is generator, the internal DIP Switch SW1 (Fig 2, 4) should be retained in the
preset off condition (1) .
