DIP switches on the P.C. Boards allow for custom configuration of
the Power Wave. To access the DIP switches:

2. Remove the wrap around cover from the power source.
3. The control board is on the center assembly facing the case front.
Locate the 8-position DIP switch and look for switch 8 of the DIP
switch.
4. Using a pencil or other small object, slide the switch to the OFF
position if the work sense lead is NOT connected. Conversely, slide
the switch to the ON position if the work sense lead is present.
5. Replace the wrap around and screws. The PC board will “read” the
switch at power up, and configure the work voltage sense lead
appropriately.
