Please note that the gate wires have new connection position - See colour marking Fig. Make also sure that you have connect the cable from the thyristors correct DS Ready for start!! -. Remove the front cover. Connect the voltage and the other cable. PS make sure that you are placing the jumper for supply voltage the correct position, 110 120V 220 240V. 10. 7.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. Then all the internal cable connectors have converted fit the new PCB. These PCB have tabs (see Fig connectors for the gate wires and other internal connections.
