3. Mount also the connector for Supply
Voltage.
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!!
-.
These PCB have white colored connectors (see Fig.
13. Mount the new PCB. Remove the old PCB. Mount the cable the PCB from the
thyristors, fans and thermal switch.
7. New PCB rev later
PS make sure that you are placing the jumper for supply voltage the
correct position, 110 120V 220 240V..
5.
Please note that the gate wires have a
new connection position -
See colour marking Fig. Please note that
the gate cable connections are different the new PCB, Check this following the cable colors figure 6
below.

8. Disconnect the voltage from terminals 1L1,
3L2 and 5L3 (main supply). Discharge the package with the new PCB
by moving earth. Disconnect the cable the PCB from the
thyristors, fans and thermal switch.5) for the gate wires and other internal connections. Discharge the tools and yourself by
touching earth (if you are not earthed).
