Always run the DC ground wire directly back to the signal return of the power supply. Do not use the chassis
ground wire as your signal return! Maple Systems recommends using an axial ferrite coil with each Panel PC to
further reduce the electrical interference that may be conducted on the power lines. Thread the positive and negative
wires of the power cable through the ferrite coil so that the coil is no more than two inches from the Panel PC's
power input.

To connect the Panel PC to power:
1. Connect the power cable to the Panel PC
a. Strip the power cable shield to expose 2" of the black and red wires.
b. Strip about ¼" of insulation from the black and red wires.
c. Thread the black and red wires through the ferrite core. The shield wire must be outside.
d. Connect the red wire to the DC positive (+) input of the Panel PC power terminal.
e. Connect the black wire to the DC negative (-) input of the Panel PC power terminal.
f. Connect the power cable shield wire to the Panel PC power terminal's chassis ground
input.
2. Route the power cable to the Panel PC power supply. The power cable should not be any
longer than necessary.
3. Install the power supply wires as follows (with colors shown for Maple Systems cable P/N
