Test Operation; Check Before Test Operation; Setting The Line Voltage Selecting Connector - SPEECON 7300PA series Instruction Manual

5. TEST OPERATION

To assure safety, prior to test operation, disconnect the coupling or belt which
connects the motor with the machine 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 condition.

5.1 CHECK BEFORE TEST OPERATION

After completion of installation and wiring, check for
(1) proper wiring
(2) short-circuit due to wire clippings
(3) loose screw-type terminals
(4) proper load
5.2 SETTING THE LINE VOLTAGE SELECTING CONNECTOR FOR
