12.4 Electrical Connections – Supply Voltage
CAUTION
FIRE HAZARD!
TO AVOID THE RISK OF PROPERTY DAMAGE, PERSONAL INJU-
RY OR FIRE, USE ONLY COPPER CONDUCTORS.
IMPORTANT NOTE: USE COPPER CONDUCTORS
ONLY FROM DISCONNECT OR ELECTRICAL PANEL
TO THE AIR HANDLER.
Knockouts are provided on the air handler top panel and
sides of the cabinet to allow for the entry of the supply
voltage conductors, as shown in Figure 13. Separate
knockouts must be used for two circuit heat kits. Unless
Single Point Wiring Kit (SPW-01) is used. If the knockouts
on the cabinet sides are used for electrical conduit, an
adapter ring must be used in order to meet UL1995 safety
requirements. An NEC or CEC approved strain relief is
to be used at this entry point. Some codes/municipalities
require the supply wire to be enclosed in conduit. Consult
your local codes.
