4.2 Test Run Checkpoints
To assure safety, prior to initial operation, disconnect the machine coupling so that the motor is isolated 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 test run.
o Wiring and terminal connections are correct.
o No short-circuit caused by wire clippings.
o Screw-type terminals are securely tightened.
o Motor is securely mounted
o All items are correctly earthed (grounded).
4.3 Setting the Line Voltage Using Jumper (For 400V Class 18.5kW and Above)
Set the line voltage jumper according to the main circuit power supply. (See Figure 13.) Insert the jumper at the appropriate
location corresponding to the input line voltage. It has been preset at the factory to 440V.
