Mount also the connector for Supply
Voltage. Disconnect the cable the PCB from the
thyristors, fans and thermal switch. Discharge the package with the new PCB
by moving earth. Disconnect the voltage from terminals 1L1,
3L2 and 5L3 (main supply).
This part valid replacing broken PCB with new PCB with the same revision newer,
Step step.
