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.
11. Mount the new PCB.
Mount also the connector for Supply
Voltage.

Replacing PCB marked Rev later (also for 690V Rev I)
These PCB have white colored connectors (see Fig.
3. Discharge the tools and yourself by
touching earth (if you are not earthed).

6. Discharge the package with the new PCB
by moving earth.
4. Remove the old PCB.
Fig. Disconnect all cables from the terminals to.
10. Disconnect the cable the PCB from the
thyristors, fans and thermal switch. Connect the voltage and the other cable. New PCB rev I
or later. 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.
7. Mount the front cover. Remove the front cover. DS
Ready for start!!
-. Disconnect the voltage from terminals 1L1,
