Installing the Ferrite Bead for DC Power and Return Cables
Add a ferrite bead to the DC power and return cables of the master module. Install the
bead with a single loop.
1. Open ferrite bead with the depressions facing up.
2. Wrap the DC power and return cables around the ferrite bead twice if two turns of
the cable fit inside the ferrite, otherwise simply clamp the ferrite onto both cables.
