WSHP-SVX02A-EN 17
Controls Using 24 VAC
Before installing any wire, refer to the
electrical access locations on the unit
submittals located on pages 7 through
9.
Ensure that the AC control wiring be-
tween the controls and the unit’s ter-
mination 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 other-
wise specified.
Do not run the AC low voltage wiring
in the same conduit with the high volt-
age power wiring.
Low voltage connection diagrams are
shown in Figure 9. Optional desuper-
heater fuse installation shown in Fig-
ure 10.
