PS make sure that you are placing the jumper for supply voltage the
correct position, 110 120V 220 240V. Remove the old PCB.
Mount also the connector for Supply
Voltage.12.

Ready for start!!
-. Disconnect the voltage from terminals 1L1,
3L2 and 5L3 (main supply). Discharge the tools and yourself by
touching earth (if you are not earthed).Start here if
Replacing PCB marked Rev later (also for 690V Rev I)
These PCB have white colored connectors (see Fig. Discharge the package with the new PCB
by moving earth. Connect the voltage and the other cable.
This part valid replacing broken PCB with new PCB with the same revision newer,
Step step.
