Disconnect the cable the PCB from the
thyristors, fans and thermal switch. Disconnect the voltage from terminals 1L1,
3L2 and 5L3 (main supply).7) for the gate wires and other internal connections.
PS make sure that you are placing the jumper for supply voltage the
correct position, 110 120V 220 240V.
1.
4.
6. New PCB rev I
or later.
10. Disconnect all cables from the terminals to.
11. Mount the front cover.
See Fig 6
9. Remove the old PCB.

8. Discharge the tools and yourself by
touching earth (if you are not earthed). Discharge the package with the new PCB
by moving earth.
2.Start here if
Replacing PCB marked Rev later (also for 690V Rev I)
These PCB have white colored connectors (see Fig. Remove the front cover.12.
Mount also the connector for Supply
Voltage.
This part valid replacing broken PCB with new PCB with the same revision newer,
Step step.
5. Mount the cable the PCB from the
thyristors, fans and thermal switch.
7. Connect the voltage and the other cable.
Fig. Mount the new PCB. DS
Ready for start!!
