6. Older PCB with connectors. Mount also the connector for Supply
Voltage. Remove the front cover. Discharge the tools and yourself by
touching earth (if you are not earthed).
Fig. Remove the old PCB. New PCB rev later
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.
4. Connect the voltage and the other cable.
This chapter valid replacing broken with newer revision (rev later) PCB.
10. Discharge the package with the new PCB
by moving earth.

11. Disconnect all cables from the terminals to.
Also make sure that you have connected the cables from the thyristors
in the correct position differ from the old PCB DS

Replacing PCB marked Rev revision (Not valid for 690V). 6. Disconnect the cable the PCB from the
thyristors, fans and thermal switch. Disconnect the voltage from terminals 1L1,
3L2 and 5L3 (main supply).12
