Replace the high–frequency inverter as follows:
(1)Turn off the power to the CNC, then turn off the power to the laser
oscillator. In addition, open the main circuit breaker for the laser
oscillator.
(2)Disconnect the cables from the high–frequency inverter.
(3)Remove the four screws, then remove the inverter.
(4)Mount a new inverter, then secure it by tightening the screws.
(5)Connect the cables correctly. If the inverter output wiring is incorrect,
the turbo blower rotation may be reversed, thus contaminating the
oscillator.
(6)Set the high–frequency inverter as explained in Section 9.3.
