All 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 eld connections tKat must be made by
the installing (or electrical) contractor. All
nal electrical connections must be made
with a length of 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! To avoid possible injury
or death due to electrical shock, open
the power supply disconnect switch
and secure it in an open position
during installation.
WARNING!
T
CAUTION! UseRnly copper
conductors for eld installed electrical
wiring.Unit terminals are not
designed to accept other types of
conductors.
CAUTION!
