Control Board - Carrier 40WAU Series Installation And Maintenance Instructions Manual

After the pipe work is complete, the electrical supply can be
connected by routing the cable through the appropriate casing
holes or knockouts and connecting the supply and ground
cables to the unit's power terminal.
Be sure the power wiring and control wiring do not cross, as
this might cause disturbance on the controls side. See Fig. 12
for wiring diagram.
