Installation
F232058
The AC drive provides overload protection for
the drive motor. However, a separate 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 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 L1, L2, or L3 on the
cabinet freestanding models as all machines
are equipped with control transformers.
Do not use a phase adder on any variable-
speed machine.
