Install the transformers and current transformer, inductors, ZNR1, TR1, LEDs, bridge
rectifiers, and the fuse holders. The current transformer T3 is installed with two turns of
insulated 16 gage wire wound through the hole in the transformer and soldered into the
large holes adjacent to T3. Also wire the voltage select switch at this time.
This is the time for determining your power supply jumper configuration: For 120v
operation, equip jumpers 1, 2, and 3. For 240 v operation, use jumper 4 only.
