Checking the Three-phase Connections

Perform the following procedure to verify that the three-phases are properly connected.

1. Turn the 200V power on.

2 Log in the machine.

3. Press the [AUTO] button (but do not press START).

Note: Do not press the START button.

The vacuum pump begins operating when [AUTO] is pressed, so disconnect the

hose to verify that suction exists. If there is suction, this indicates that the wiring is

correct and the motor is rotating in the correct direction. If the air flow is reversed

(air is blowing out instead of in), then turn the main power off and reverse the three-

phase power cable’s U-phase and V-phase connections, then try again.

Caution: To avoid leaks, the hose should be pushed firmly into position, and then secured in

position with the hose band.
