INSTALLATION
Mounting location
The unit can be installed near the power cord entry of the RV or near the location of the
generator output
on the line side of the main distribution panel, or it can be installed on the load
side of the panel between the main panel and a sub panel, allowing switching for either the entire
electrical load or only designated circuits. Typical locations include under counter cabinets, below
closet compartments, inside the bed pedestal or cabinets, overhead cabinets, under-fl oor storage
compartments accessed from the vehicle exterior, etc. The chosen location must be accessible after
installation is complete to facilitate future servicing.
Cable entry and exits
A number of ¾” and 1” knockouts have been provided on all the sides (7, Fig 2) for ease of routing
the input and output cables. Choose a knockout that will facilitate installation and service within the
selected mounting area. Use 3/4” or 1” cable clamps as necessary to clamp the cables entering and
exiting the box.
Mounting
Mount the unit with screws through holes in the bottom of the unit. The unit should be screwed to a
solid surface fi rmly enough to hold its weight during vehicle operation.
Making electrical connections
1. Attach an 8 gauge earth ground wire to the transfer switch chassis ground lug (6, Fig 2). 4 studs
with serrated lock washers and nuts have been provided on the inner bottom of the case to make
grounding connections from the inner side .
2. The color code for 120 VAC wiring is as follows:
• The "Grounding" wire is bare or green.
• The "Neutral" wire is white.
• The "Line" wire is black.
1. 3. A ¾” cable clamp has been provided (4, Fig. 1). Additional ¾” and 1” knockouts have been
provided for convenience. Please ensure that a cable clamp is used for the cable entries.
4. For making fi rm connections to the terminals (T1 to T6, Fig 2) of the Transfer Relay (R1, Fig 2), please
crimp appropriate size of insulated ring / spade lugs on the ends of the conductors of the cables.
5. Connect the grounding conductors (green / bare wire) of the cables to the spare grounding studs
marked (
)
6. Two or more conductors can be spliced together using the appropriate size of twist-on type of cone
shaped, plastic insulated wire nut connector (See Fig. 3). The connector twists over the wires to make
a tight connection around the wires. A square-cut spring inside provides tension on the wires to hold
them secure. As you tighten the wire connector, the spring draws tighter around the wires
.
Fig.3. Twist-on type of wire nut connector.
To splice the wire leads using the wire nut connector, hold the bare ends
of the wires parallel to each other so that the wire tips are even, then
secure with the wire nut. Use the proper size nut. Manually tighten nuts
as tightly as possible. Verify that all connections are tightened.
