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, in-
cluding 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 con-
nections 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.

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 power block 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.
