Replace high voltage shield after wiring is
completed.
The liquid line solenoid/compressor relay ac-
cepts a variety of input voltages and is not re-
quired to match the controller’s input. See table
for relay ratings. The relay uses the 3-position
screw terminal to make the connection on the
board. This relay is designed to control smaller
compressors directly. It may also control either
the liquid line solenoid or as a pilot to the com-
pressor contactor.When connecting the wires to
the relay, the controller will be breaking one leg
of the power.
One leg of incoming power (L1) supply for the
liquid line solenoid should be connected to the
common terminal of the liquid line solenoid
relay, the right most terminal connection. The
other leg of the incoming power (L2) should be
connected directly to the solenoid lead. The re-
maining lead from the solenoid should be con-
nected to the NO (normally open) terminal, the
leftmost terminal location.
Proper wiring practices must be followed. Local
wiring codes take precedence over any informa-
tion in this bulletin.

Connect line (L1) to the right terminal position
and neutral (L2) to the left terminal position.
