On variable-speed models, the AC drive provides
thermal 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 serial plate on the back of the
washer-extractor for recommended circuit breaker
requirements size.
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 equipment labeled with the CE mark.
Refer to serial plate for recommended circuit breaker
size and determine wire size based on local code
requirements.
Refer to serial plate for recommended wire sizes for
runs up to 50 feet (15.24 meters). Use next larger size
for runs of 50 to 100 feet (15.24 to 30.48 meters). Use
2 sizes larger for runs greater than 100 feet (30.48
meters).
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 (current edition) or accepted
European standards for equipment labeled with the CE
mark. The ground connection must be made to a
proven earth ground, not to conduit or water pipes.
Refer to Figure 25 and 26.
