The AC drive provides thermal overload protection for
the drive motor. However, a separate circuit breaker or
electrical supply disconnecting device must be
installed for complete electrical overload protection.
This prevents damage to the AC drive by
disconnecting all legs if one should be lost
accidentally. Check the data plate on the back of the
washer-extractor or refer to Table 14 for circuit
breaker recommendations.
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.
Use wire sizes indicated in Table 14 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 250-95 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.
Circuit Breakers
The machines are to be connected to individual
common trip circuit breakers. Use only UL 489 rated
circuit breakers. Fuses are not to be used in any
installations. (Fuses may fail separately causing a
single-phase voltage condition.) A single-phase
condition will cause the other lines to have a
considerable change in current draw suddenly, which
may cause the inverter to fail. Do not install more than
one machine per breaker and do not install any other
equipment on the breaker supplying the machine. If
there is a “stinger” leg (also known as high leg, red
leg, etc.) it must be connected to L3 of the terminal
block of the machine. A line reactor is highly
recommended.
Grounding
All equipment should be grounded with a proven earth
ground. Do not use water pipes or electrical conduit as
an earth ground path. All grounding and wiring must
conform to local and national electrical codes.
Wire Size
Wire size must meet or exceed all codes for breaker
size.
Use either SO type cord or flex conduit with stranded
copper conductors of prescribed size for power supply
between machine and wall. Because this machine
vibrates in normal operation, hard conduit may
become loose and cause wire abrasion and solid
conductor wires may break during normal operation
on vibrating machines.
Do not use a phase adder on any variable-
speed machine.

CAUTION
Failure to provide this equipment with a
proper proven earth ground may result in
a severe shock hazard and may increase
EMI emissions.
