INSTALL ELECTRICAL CONNECTION
WARNING: The unit cabinet must have an uninter-
rupted, unbroken electrical ground to minimize the pos-
sibility of personal injury if an electrical fault should
occur. This ground may consist of an electrical wire
connected to the unit ground lug in the control compart-
ment, or conduit approved for electrical ground when
installed in accordance with NEC (National Electrical
Code) ANSI/NFPA (latest edition) and local electrical
codes. In Canada, follow Canadian Electrical Code CSA
(Canadian Standards Association) C22.1 and local elec-
trical codes. Failure to adhere to this warning could result
in personal injury or death.
CAUTION: Failure to follow these precautions could
result in damage to the unit being installed:
1. Make all electrical connections in accordance with
NEC ANSI/NFPA (latest edition) and local electrical
codes governing such wiring. In Canada, all electrical
connections must be in accordance with CSA standard
C22.1 Canadian Electrical Code Part 1 and applicable
local codes. Refer to unit wiring diagram.
2. Use only copper conductor for connections between
field-supplied electrical disconnect switch and unit.
DO NOT USE ALUMINUM WIRE.
3. Be sure that high-voltage power to unit is within
operating voltage range indicated on unit rating plate.
4. Do not damage internal components when drilling
through any panel to mount electrical hardware, con-
duit, etc. On 3-phase units, ensure phases are balanced
within 2 percent. Consult local power company for
correction of improper voltage and/or phase imbal-
ance.
