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’
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 240V for a
200 V drive or above 480V for a 400V
drive, either ask the power company if their
representative can lower the voltage or
install a bucking 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 user-serviceable parts inside the AC drive.
Tampering with the drive will void the warranty
Dangerous voltage 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 the machine
before removing the control box cover, and before attempting any service
procedures.
