Procedure 3: Checking the Peripheral Equipment

The following equipment may need to be checked. Follow the

manufacturers’ procedures when checking this equipment.

1. A protective device, such as a circuit breaker, may have tripped or

a fuse may have blown.

2. A switching device, such as a contactor, may not be closing at the

correct time.

3. Conductors may require repair or replacement.

4. Connection cables to the motor or high resistance connections to

ground may need to be checked. Follow NEMA standard

procedure WC-53.

5. Motor insulation may need to be checked. Follow NEMA standard

procedure MG-1. Do not apply high voltage to U, V, or W. Do not

connect the high potential dielectric test equipment or insulation

resistance tester to the drive controller since the test voltages

used may damage the drive controller. Always disconnect the

drive controller from the conductors or motor while performing

such tests.

CAUTION

DIELECTRIC TESTS WHILE CONNECTED

Can Cause Equipment Damage

• Do not perform high potential dielectric tests on circuits while the

circuits are connected to the drive controller.

• Any circuit requiring high potential dielectric tests must be

disconnected from the drive controller prior to performing the test.

Failure to follow these instructions can result in injury or

equipment damage.
