Note: This unit includes a small, wiring compartment for
making electrical connections to the main power
1. Remove the wire compartment cover screw and set
aside the screw and cover in a secure place (Figure 5).
2. Pull the loose black, white and green wires out from the wire
compartment (additional wires will be present).
Install an approved cable connector to the hole in the wire
compartment cover (not included) to protect the wire from
being cut by the sharp metal of the hole in the cover. Run a black

supply through the cable connector. Connect all wires
from the supply to their corresponding wires within the
wire compartment (Figure 6). Use approved methods for
all connections.

and replace wire compartment cover securing it with the
screw that was removed earlier.
