Input Voltage Requirements

For voltages above or below listed specifications,

contact your power company or local electrician.
If machine is intended for four-wire service, a neutral

leg must be provided by power company.
If a delta supply system is used on a four-wire model,

connect high leg to L3.

IMPORTANT: Improper connections will result in

equipment damage and will void warranty.

Circuit Breakers and Quick Disconnects

Single-phase machines require a single-phase inverse-

time circuit breaker. Three-phase machines and

variable-speed machines require a separate, three-

phase inverse-time circuit breaker to prevent damage

to the motor by disconnecting all legs if one should be

lost accidentally. Check the nameplate decal on the

back of the machine. Refer to Table 10 through

in this section for model-specific circuit breaker

requirements.

IMPORTANT: All quick disconnects should

comply with the above specifications. DO NOT use

fuses instead of circuit breakers.

Connection Specifications

IMPORTANT: Connection must be made by a

qualified electrician using wiring diagram provided

with machine, or according to accepted European

standards for CE-approved equipment.

Connect machine to an individual branch circuit not

shared with lighting or other equipment. Shield

connection in a liquid-tight or approved flexible

conduit. Copper conductors of correct size must be

installed in accordance with National Electric Code

(NEC) or other applicable codes.
Use wire sizes indicated in the Electrical Specifications

chart for runs up to 50 feet (15 m). Use next larger size

for runs of 50 to 100 feet (15 to 30 m). Use two sizes

larger for runs greater than 100 feet (30 m).

Grounding

For personal safety and proper operation, the machine

must be grounded in accordance with state and local

codes. If such codes are not available, grounding must

conform to the National Electric Code, article 250

(current edition). The ground connection must be

made to a proven earth ground, not to conduit or water

pipes.

Never touch terminals or components of

the AC inverter drive unless power is

disconnected for three minutes.

DANGER

Hazardous Rotation Speed. Will cause

serious injury when controlling AC

inverter drive with a parameter unit,

safety features are bypassed allowing

basket to rotate at high speeds with the

door open. Place large sign on front of

machine to warn people of imminent

danger.

W361

DANGER

Electrically heated machines DO NOT

require dual power sources. Do not

connect customer power or customer
