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.

CAUTION

Do not use a phase adder on any variable- speed machine.

SW037

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.

Installation

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.
