TRIAL OPERATION
To ensure safety, prior to initial operation, disconnect the machine coupling so that the motor is iso-
lated from the machine. If initial operation must be performed while the motor is still coupled to the
machine, use great care to avoid potentially hazardous conditions. Check the following items before a
trial run:
· Wiring and terminal connections are proper.
· Wire clippings and other debris removed from the unit.
· Screws are securely tightened.
· Motor is securely mounted.
· All items are correctly grounded.
