General Recommendations
All wiring must comply with local codes and the National
Electric Code.Typical field wiring diagrams are included at
the end of the manual. Minimum circuit ampacities and
other unit electrical data are on the unit nameplate and in
Table 67. See the unit order specifications for actual
electrical data. Specific electrical schematics and
connection diagrams are shipped with the unit. Important: Do not allow conduit to interfere with other
components, structural members or
equipment. Control voltage (115V) wiring in
conduit must be separate from conduit
carrying low voltage (<30V) wiring. To
prevent control malfunctions, do not run
low voltage wiring (<30V) in conduit with
conductors carrying more than 30 volts.
NOTICE: WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
NOTICE:
Use Copper Conductors Only!
Unit terminals are not designed to accept other types
of conductors. Failure to use copper conductors could
result in equipment damage.
