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