Checking the Three-phase Connections
Perform the following procedure to verify that the three-phases are properly con-
nected.
1 Turn the 200V power on.
2 Log in the machine.
3 Press the [AUTO] button (but do not press START).
Note
1. Do not press the START button.
2. The vacuum pump begins operating when [AUTO] is pressed, so disconnect the hose to ver-
ify 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.
