6. Have a licensed electrician wire the primary
pedestal to power. The locations of where the
Line, Neutral, and Ground wires connect to the
grounding plate are shown above.

Tuning the Pedestals
Tuning the pedestals is not a standard part of initial
installation; the system should be left at the factory
default setting of minimum capacitance (all
jumpers out). If the pedestals are placed near a lot
of metal, however, the current in the system may
be reduced and the performance can be reduced.
If the performance is unacceptable and the
maximum burst current is not at least 30A, you can
use the following procedure to optimize the tuning
until maximum peak current is achieved.

If the performance is unacceptable and the

1. Remove the base covers on both pedestals
and locate the tuning jumpers on the main
circuit board on the primary pedestal and the
secondary capacitor board. See Figure 1.
circuit board on the primary pedestal and the
secondary capacitor board. See Figure 1.
•
Primary tuning jumpers: J2, J3, J4
•
Secondary tuning jumpers: J1, J2
2. Ensure the tuning jumpers are set to their
default values. See Table 1 (primary) or
Table 2 (secondary).
Table 2 (secondary).
3. Adjust the tuning jumpers on the primary
pedestal up one step (for example, from Step
0 to Step 1).
0 to Step 1).
4. Check the current.
•
If the current is less than before you adjust
the capacitance, you are detuning the
pedestal. Return to the default setting. You
are done.

are done.
•
If the current goes up, you are tuning the
pedestal in the correct direction. Keep
adding capacitance until you find the peak
current.
adding capacitance until you find the peak
current.
5. If you get to step 8 in Table 1 (all jumpers in)
and the current is still increasing, go to the
secondary pedestal and increase the
capacitance one step. Then go back to the
primary pedestal, set it back to step one (all
jumpers removed) and start adding
capacitance on the primary one step at a time.
