8. 7. Remove the old PCB. 4. Step step. Disconnect all cables from the terminals 1 3. Mount the cable the PCB from the thyristors, fans and thermal switch. Mount the front cover.Start here if Replacing older PCB marked Rev older (for 690V Rev older). 11. 4. 9. Connect the voltage and the other cable. 12. 1. New PCB rev I or later. Mount also the connector for Supply Voltage. 2. Please note that the gate wires are connected differently the new PCB. Then all the internal cable connectors have converted fit the new PCB. Discharge the tools and yourself by touching earth (if you are not earthed). Discharge the package with the new PCB by moving earth. 5. These PCB have tabs (see Fig connectors for the gate wires and other internal connections. Remove the front cover. Disconnect the cable the PCB from the thyristors, fans and thermal switch. PS make sure that you are placing the jumper for supply voltage the correct position, 110 120V 220 240V. This chapter valid replacing the broken PCB with the newest revision (rev later) PCB. 10. Disconnect the voltage from terminals 1L1 3L2 and 5L3 (main supply). Mount the new PCB. 6. Please note that the gate wires have new connection position - See colour marking Fig. The needed connectors are enclosed in the new PCB package. Cut the old wires, and exchange the terminals for the gate wires, fan wires, and thermal switch the new ones included in the package. Fig. Make also sure that you have connect the cable from the thyristors correct DS Ready for start!! -
