8.5 ELECTRICAL CONNECTIONS
IMPORTANT NOTE: USE COPPER CONDUCTORS ONLY.
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 17. 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.

• Outside the air conditioner, do not route the remote controller
wiring and transmission wiring together with other electrical
wiring. Keep the remote controller wiring and transmission
wiring at least 2 in. (50mm) away from the power wiring and
other electrical wiring. Effects of electrical interference
(external noise) may result in malfunction and breakdown.
If the power supply voltage is 208V, change the transformer wire
connection from the 240V terminal to the 208V terminal on both
transformers.
