Electrical - Line Voltage
All field installed wiring, including electrical ground, must comply
with the National Electrical Code as well as all applicable local
codes. Refer to the unit electrical data for fuse sizes. Consult
wiring diagram for field connections that 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 National
Electric Code, whichever is applicable.
Power Connection
Line voltage connection is made by connecting the incoming
line voltage wires to the "L" side of the contactor as shown in
Figures 21a through 21c. Consult Tables 8a through 8c for
correct fuse size.
