3.5 ELECTRICAL INSTALLATION
The AC drive requires a clean power supply free from voltage spikes and surges. A voltage
monitor should be used to check incoming power. The customer local power company may provide
such a monitor.
The AC drive provides for an internal circuit breaker. A separate circuit breaker governs the
control circuit.
If input voltage measures above 230V for a 200V drive, or above 440V for a 400V drive,
either ask the power company if their representative can lower the voltage or install a step – down
transformer kit available from the manufacturer. Voltages above 250V and 490V require additional
measures. Contact the distributor or the manufacturer for assistance.
This machine must be installed, adjusted, and serviced by qualified electrical
maintenance personnel familiar with the construction and operation of this type
of machinery. They must also be familiar with the potential hazards involved. If
this warning is not observed, personal injury or equipment damage resulting in
voiding the warranty may result.
When controlling the AC drive with a parameter unit, the machine’s computer
and its safety features are bypassed. This would allow the basket to rotate at high
speeds with the door open. When using a parameter unit to control the AC drive,
a large sign should be placed on the front of the machine warning people of the
imminent danger.
