V. ELECTRICAL CONNECTIONS
WARNING: The unit cabinet must have an uninterrupted, unbroken electrical ground to minimize the possibility of personal injury if an electrical fault should occur. This ground may consist of electrical wire connected to the unit ground lug in the control compartment or conduit approved for electrical ground when installed in accordance with the NEC and local electrical codes. Failure to adhere to this warning could result in personal injury.
CAUTION: Failure to follow these precautions could result in damage to the unit being installed:
A.Field Power Supply (Fig. 5-7)
1.Make all electrical connections in accordance with NEC ANSI/NFPA (American National Standards Institute/ National Fire Protection Association) 70, latest edition, and local electrical codes governing such wiring. Refer to unit wiring diagram.
2.Use only copper or
3.Voltage to compressor terminals during operation must be within voltage range indicated on unit name- plate (also see Table 4). On
