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.
