Please note that the gate wires have a
new connection position -
See colour marking Fig. Older PCB with connectors. New PCB rev later
PS make sure that you are placing the jumper for supply voltage the
correct position, 110 120V 220 240V.
These PCB have white colored connectors (see Fig.Start here if
Replacing PCB marked Rev revision (Not valid for 690V). Remove the old PCB. Remove the front cover.

This chapter valid replacing broken with newer revision (rev later) PCB. Please note that
the gate cable connections are different the new PCB, Check this following the cable colors figure 6
below.
Also make sure that you have connected the cables from the thyristors
in the correct position differ from the old PCB DS
Ready for start!!
