INSTALLATION PROCEDURES

The AC drive requires a clean power supply free from voltage spikes and surges. A voltage
monitor should be sued to check incoming power. The customer’s 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 a 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.
Never touch terminals or components of the AC drive unless power is
disconnected and the “CHARGE” indicator LED is off. The AC drive retains
potential deadly voltage for some time after the power is disconnected. There
are no users – serviceable parts inside the AC drive. Tampering with the drive
will void the warranty.
Dangerous voltages are present in the electrical control boxes and at the motor
terminals. Only qualified personnel familiar with electrical test procedures test
equipment, and safety precautions should attempt adjustments and
troubleshooting. Disconnect power from form the machine before removing the
control box cover, and before attempting any service procedures.
