Do not use the power supply used to provide power to the OIT to power switching relays, solenoids, or other active devices.
4
STEPS:
1. Connect the power cable to the OIT as follows:
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 OIT power terminal.
E. Connect the black wire to the DC negative (-) input of the OIT power terminal.
F. Connect the power cable shield wire to the OIT power terminal’s chassis ground input.
2. Route the power cable to the OIT 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
