5. TEST OPERATION
To assure safety, disconnect the coupling or belt which connects the motor with the machine prior to
test operation, so that motor operation is isolated. If an operation must be performed while the motor
is directly connected to the machine, use great care to avoid any possible hazardous conditions.
5.1 CHECK BEFORE TEST OPERATION
After completion of the installation and wiring, check for
(1) proper wiring
(2) short-circuit due to wire clippings
(3) loose screw-type terminals
(4) proper loading
