Electrical - Power Wiring
CAUTION! Use only copper conductors for fi eld installed
electrical wiring. Unit terminals are not designed to accept
other types of conductors.
Electrical - Line Voltage
- All fi eld 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 fi eld connections that must be made by
the installing (or electrical) contractor. All fi nal electrical
connections must be made with a length of fl exible 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.
Figure 15: Single Phase Line Voltage Field Wiring.
Three phase wiring is similar except that all three
power wires are directly connected to the contactor.
Unit Power Supply
(see electrical table for wire and
breaker size)
Note: 460V units with
ECM motor require
a neutral wire.
WARNING! Disconnect electrical power source to prevent
injury or death from electrical shock.
CAUTION!
WARNING!
Power Connection -
Line voltage connection is made by
connecting the incoming line voltage wires to the “L” side
of the contractor as shown in Figure 15. Consult electrical
data tables for correct fuse size.
Transformer -
All 208/230 voltage units are factory wired
for 208 volt. If supply voltage is 230 volt, installer must
rewire transformer. See wire diagram for connections.
