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