Electrical Installation

WARNING

Hazardous Voltage. Can cause shock, burn or cause death. Allow machine power to remain off for two minutes prior to working in and around AC inverter drive.

W359

WARNING

Hazardous Voltage. Can cause shock, burn or death. Verify that a ground wire from a proven earth ground is connected to the lug near the input power block on this machine.

W360

Input Voltage Requirements

If input voltage measures above 240 Volt for a

200 Volt drive or above 440 Volt for a 400 Volt drive, ask the power company to lower voltage. For voltages above or below listed specifications, contact Customer Service or a distributor for buck/ boost transformer recommendation.

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.

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. Proper conductors of correct size must be installed in accordance with National Electric Code 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).

The UW50 is provided with a thermal overload protector in the drive motor windings and a separate fuse for the control circuit. However, a separate three- phase circuit breaker must be installed for protection against shorts. DO NOT USE FUSES.

For proper over current protection, the circuit breaker should be a 30 Amp capacity unit rated for

208-240 Volts and should be a three-phase breaker so that in the event that one leg should be removed from the machine, all three legs will be disconnected to prevent damage to the motor.

WARNING

Turn off power and water before attempting any maintenance, repairs, or service, or before opening any service panel or door. This machine must be connected and grounded in accordance with the National Electric Code and/or any other applicable code.

W448

The wire for the service connection should be a minimum size of 8 gauge (AWG) for 208-240 Volt installations. Refer to Table 7.

The connections should be made by a qualified electrician and in accordance with the wiring diagram provided with the machine.

When the machine is started, check that the cylinder rotates in the correct direction during the spin (extract) step, i.e., clockwise as seen from the front of the machine. If the machine rotates in the wrong direction, two of the lines are to be interchanged at the power connection terminal (reverse L1 and L2 – do not reverse L3).
