Electrical - Line Voltage
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.
