The AC drive provides overload protection for
the drive motor. However, a separate three-
phase circuit breaker or single-phase circuit
breaker (if machine is a single-phase model)
must be installed for complete electrical
overload protection. This circuit breaker must
disconnect all poles when in the open position.
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 the
Electrical Specifications chart in this
subsection for circuit breaker requirements.
Note: 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 the Electrical
Specifications chart for runs up to 50 feet.
Use next larger size for runs of 50 to 100 feet.
Use 2 sizes larger for runs greater than
100 feet.
For personal safety and for 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.
If a delta supply system is used, the high
leg may be connected to L3 on the cabinet
freestanding models as all machines are
equipped with control transformers.
Note: Timers or similar devices that could
switch off the machine automatically are not to
be installed, whether in the machine’s supply
circuit or elsewhere. Do not use a phase adder on any variable-
speed machine.
