These PCB have white colored connectors (see Fig. Discharge the tools and yourself by
touching earth (if you are not earthed).
7. Older PCB with connectors. Disconnect the cable the PCB from the
thyristors, fans and thermal switch. Please note that
the gate cable connections are different the new PCB, Check this following the cable colors figure 6
below.

3. Remove the front cover.
2. 6. Disconnect all cables from the terminals to. Mount also the connector for Supply
Voltage.
Please note that the gate wires have a
new connection position -
See colour marking Fig.
Also make sure that you have connected the cables from the thyristors
in the correct position differ from the old PCB DS
