6. Discharge the tools and yourself by
touching earth (if you are not earthed).
11.Start here if
Replacing PCB marked Rev revision (Not valid for 690V).

Step step. Mount the cable the PCB from the
thyristors, fans and thermal switch. Disconnect the cable the PCB from the
thyristors, fans and thermal switch.12

Please note that the gate wires have a
new connection position -
See colour marking Fig. Remove the old PCB. Please note that
the gate cable connections are different the new PCB, Check this following the cable colors figure 6
below.

7. Connect the voltage and the other cable. Disconnect the voltage from terminals 1L1,
3L2 and 5L3 (main supply). New PCB rev later
PS make sure that you are placing the jumper for supply voltage the
correct position, 110 120V 220 240V.

This chapter valid replacing broken with newer revision (rev later) PCB. Older PCB with connectors. Discharge the package with the new PCB
by moving earth.
Also make sure that you have connected the cables from the thyristors
in the correct position differ from the old PCB DS
