circuit can cause circuit overload and/or
imbalance in motor phasing. Install
proper No Fuse Breaker (NFB)
according to kW output of compressor.
3.
Ensure incoming service has adequate
ampere rating.
4.
Ensure supply line has the same
electrical
Characteristics (voltage, cycles and
phase) as the machine.Wiring for
Variable Speed Drive
or typical
Wye-
Delta Start
. See page 1 for advantages
of
