Electrical Installation

The AC inverter 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.
If input voltage measures above 240V for a 220V
drive or above 480V for a 400V drive, ask the power
company to lower the voltage. As an alternative, a
step-down transformer kit is available from the
distributor.
The AC drive provides overload protection for the
drive motor. However, a separate single or three phase
circuit breaker must be installed for complete
electrical overload protection. This prevents damage
to the motor by disconnecting all legs if one should be
lost accidentally. Check the data plate on the back of
the washer-extractor or consult Tabl e 6 for circuit
breaker requirements.
IMPORTANT: Do NOT use fuses in place of a
circuit breaker.
The washer-extractor should be connected to an
individual branch circuit not shared with lighting or
other equipment.
The connection should be shielded in a liquid tight or
approved flexible conduit with proper conductors of
correct size installed in accordance with the National
Electric Code or other applicable codes. The
connection must be made by a qualified electrician
using the wiring diagram provided with the washer-
extractor, or according to accepted European standards
for CE-approved equipment.
Use wire sizes indicated in Tabl e 6 for runs up to
50 feet.
Use next larger size for runs of 50 to 100 feet. Use two
sizes larger for runs greater than 100 feet.
For personal safety and proper operation, the washer-
extractor must be grounded in accordance with state
and local codes. If such codes are not available,
grounding must conform with the National Electric
Code, article 250-95. The ground connection must be
made to a proven earth ground, not to conduit or water
pipes.
