NOTE: 

Since not all local codes allow the mounting of a 
disconnect on the unit, please confirm compliance with 
local code before mounting a disconnect on the unit.

Electrical line must be sized properly to carry the load. USE 
COPPER CONDUCTORS ONLY. Each unit must be wired with 
a separate branch circuit fed directly from the meter panel and 
properly fused.

Refer to Figures 22, 23, 24 and 24 for typical field wiring and to 
the appropriate unit wiring diagram mounted inside control 
doors for control circuit and power wiring information.

Power Wiring Detail

Units are factory wired for the voltage shown on the unit 
nameplate. Refer to Electrical Data Table 8 to size power 
wiring, fuses, and disconnect switch.

Power wiring is brought into the unit through the side of the unit 
or the basepan inside the curb.

Figure 22: Field Wiring Disconnect - Cooling Unit With/Without Electric Heat and All Units With VFD Option

Avoid damage to internal components if drilling holes for 
disconnect mounting.

When connecting electrical power and control wiring to 
the unit, water-proof connectors must be used so that 
water or moisture cannot be drawn into the unit during 
normal operation. The above water-proofing conditions 
will also apply when installing a field supplied disconnect 
switch.
