Installation
Controls Using 24 VAC
Before installing any wire, refer to the
electrical access locations in
Dimension section of this manual.
Ensure that the AC control wiring
between the controls and the unit’s
termination point does not exceed
three (3) ohms/conductor for the
length of the run.
Note:
Resistance in excess of 3-
ohms per conductor may
cause component failure due
to insufficient AC voltage
supply.
Check all loads and conductors for
grounds, shorts, and mis-wiring.
Use copper conductors unless
otherwise specified.
Do not run the AC low voltage wiring
in the same conduit with the high
voltage power wiring.
Low voltage connection diagrams for
basic and deluxe 24 volt control
packages mounted on 1/2 through 5
ton equipment sizes are shown in
Figure 62
