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.
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.
CAUTION! Use only copper conductors for field installed electrical
wiring. Unit terminals are not designed to accept other types of
conductors.
