Step 6 — Wire Field Power Supply
Connections

ELECTRICAL–LINE VOLTAGE — All field-installed wir-

ing, including electrical ground, must comply with the National

Electrical Code (NEC) as well as all applicable local codes. Re-

fer to Tables 4 and 5 for fuse sizes. Refer to Table 6 for blower

speed wiring. See Fig. 10 for field connections or the electrical

diagram located on the back of the electrical compartment front

panel. All electrical connections must be made by the installing

(or electrical) contractor. All final electrical connections must

be made with a length of flexible conduit to minimize vibration

and sound transmission to the building.
General Line Voltage Wiring — Be sure the available

power is the same voltage and phase shown on the unit

serial plate. Line and low voltage wiring must be done in

accordance with local codes or the NEC, whichever is appli-

cable.
POWER CONNECTION
Units Equipped with Disconnect — Connect incoming line

voltage to the disconnect switch and ground wire to the ground

lug provided inside the electrical compartment.
Units without Disconnect — Line voltage connection is made

by connecting the incoming line voltage wires to the line

side(s) of the contactor.
208/230-VAC OPERATION — All commercial 208/230-v

units are factory wired for 208-v single-phase operation. For

230-v single-phase operation the primary voltage to the trans-

former must be changed. Remove the red lead from the com-

pressor contactor capping it with a wire nut and connecting the

orange 230-vac lead wire from the transformer to the compres-

sor contactor.
NOTE: Failure to change the primary voltage lead when using

240-vac line voltage may result in electrical component dam-

age and intermittent system failure.

WARNING

Electrical shock can cause personal injury or death. When

installing or servicing system, always turn off main power

to system. There may be more than one disconnect switch.
