Connections
Connections to the Accessory 47, 48, and 49 control
modules are shown in Table G. Also refer to the labels in
Figure 1 and to Wiring Diagram 363165 or 383880.
Barrier screw type terminals accept #22–12 AWG Cu
control wiring. Tighten terminals to 12 inch–pounds.
The control modules have t wo colored leads
pre–connected to the O and C terminal bus on the RC
switch. A yellow wire runs between the O terminals; and
orange/black wire runs between the C terminals.
Connect your control wiring for the module to terminals
2, 3,and4 on the modules. Terminal 2 is not used on
Accessory 47 and terminal 1 is never used.
For dc modules be sure to
connect terminal 4 to negative (–).
Connect your control wiring for the R C switch (coil
voltage) to terminal 5 on the control module and
terminal L on the RC switch. If the line voltage (service)
isthesameasthecoilvoltage,thecontrolvoltagecan
come di rectly from the poles of the RC switch.
