PROCEDURE 6—MAKE ELECTRICAL CONNECTIONS
WARNING: To avoid personal injury or death, do not supply power to unit with compressor terminal box cover
removed.
Be sure field wiring complies with local and national fire, safety, and electrical codes, and voltage to system is within limits shown on unit rating
plate. Contact local power company for correction of improper voltage. See unit rating plate for recommended circuit protection device.
NOTE:
Operation of unit on improper line voltage constitutes abuse and could affect unit reliability. See unit rating plate. Do not install unit in
system where voltage or phase imbalance may fluctuate above or below permissible limits.
NOTE:
Use copper wire only between disconnect switch and unit.
NOTE:
Install branch circuit disconnect per NEC of adequate size to handle unit starting current. Locate disconnect within sight from and readily
accessible from unit, per Section 440-14 of NEC.

WARNING: The cabinet must have an uninterrupted or unbroken ground according to NEC, ANSI/NFPA 70-1993, and
local codes to minimize personal injury if an electrical fault should occur. This may consist of electrical wire or conduit
approved for electrical ground when installed in accordance with existing electrical codes. A failure to follow this warning
could result in an electrical shock, fire, or death.
B.
Connect Ground and Power Wires
Connect ground wire to ground connection in control box for safety. Connect power wiring to contactor. (See Fig. 7.)
