Mount also the connector for Supply
Voltage. New PCB rev I
or later. Discharge the package with the new PCB
by moving earth. Discharge the tools and yourself by
touching earth (if you are not earthed).
PS make sure that you are placing the jumper for supply voltage the
correct position, 110 120V 220 240V.Start here if
Replacing PCB marked Rev later (also for 690V Rev I)
These PCB have white colored connectors (see Fig
