it. Failure to wire unit on independent
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 VSD.
5. Refer to amp load information on motor
tag and use correctly sized wiring. Be sure
to consider distance between power
supply and machine.
6. Install surge protection device between
