All fuses Class RK-5
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.
