Replacing PCB marked Rev revision (Not valid for 690V). Discharge the tools and yourself by
touching earth (if you are not earthed). New PCB rev later
PS make sure that you are placing the jumper for supply voltage the
correct position, 110 120V 220 240V. Please note that
the gate cable connections are different the new PCB, Check this following the cable colors figure 6
below. Discharge the package with the new PCB
by moving earth.
