touching earth (if you are not earthed). Connect the voltage and the other cable. Disconnect the cable the PCB from the
thyristors, fans and thermal switch.
1. Remove the old PCB.
PS make sure that you are placing the jumper for supply voltage the
correct position, 110 120V 220 240V. New PCB rev I
or later. Disconnect the voltage from terminals 1L1,
3L2 and 5L3 (main supply).

Ready for start!!
-. Mount the cable the PCB from the
thyristors, fans and thermal switch.

This part valid replacing broken PCB with new PCB with the same revision newer,
Step step.
Mount also the connector for Supply
Voltage.
8. Discharge the package with the new PCB
by moving earth
