ELECTRICAL INSTALLATION

CAUTION It is important that this procedure be performed by a
qualified electrician prior to energizing the unit.

The Model 2081 is designed to operate using either 208-230 VAC
three–phase 60 Hz or 400 VAC three phase 50 Hz power. The
appropriate power requirements are determined when the order is
placed. Other power ratings are available on a special order basis.

1. The branch circuit supplying power to the motor base should

be protected from excess current according to local electrical
codes. ETS-Lindgren has provided a three pole circuit breaker
integral to the relay control enclosure. This circuit breaker also
serves as a service switch and removes motor power from both
the control enclosure assembly and the motor.

WARNING With the circuit breaker in the off position some parts
with AC hazards still present a potentially lethal shock hazard.

2. Check that the conductor size is adequate for the motor load

and the distance from the mains source. Improperly sized
conductors will lead to a high voltage drop in the power
conductors and cause reduced starting torque and premature
motor failure.

3. The motor base assembly is provided with an unterminated

flexible conduit with input power leads exposed. This flexible
conduit is to be terminated into a junction box fitted on or near
the motor base. Terminate the power leads of the motor base
assembly according to local electrical code requirements.
