Connections and Utilization
6
The copper HF jumper illustrate above has to be properly configured for the intended input voltage the system
will be connected to. Failure to properly configure the HF jumper can result in unwarranted damage to the
system. To relocated the jumper, simply loosen the two ¼-20 brass bolts holding the jumper in place. (Do not
completely remove the bolts). Loosen the adjacent bolt to the right or left of the jumper, depending on which
voltage configuration it is currently in. Slide the jumper from beneath the bolts and re-install the jumper in the
alternate position. The center bolt/standoff is always connected to the jumper. Tighten all bolts after re-locating
the jumper. A schematic illustrating the position of the jumper for each line voltage is located in the cabinet next
to the location of the jumper.
