SecTIOn 3 | Installation
a. Disable the Time Delay Circuit by changing the position of DIP Switch SW1 (fig 2)
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 Utility/Shore Power
Cord (rV). A 3/4" cable clamp (4, fig 4) 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 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 4):
- 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 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 1) of the inverter power cord (1, fig 1) to the
output of the inverter (fig 4). As pointed out earlier on page 8, 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 to one of the receptacles of the NeMA-20r
Duplex receptacle (3, fig 1; fig 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, 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.
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 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 NeMA5-20r Duplex
receptacle (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.
g. 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) .
