• Place the communication cable
inside the ferrite bead groove.
• Position the ferrite beads as close
as possible to the end of the
cable that connects to the DB9
connector of the UPS.
• Close the ferrite bead so that the
ferrite bead’s case snaps closed
with the cable routed inside the
ferrite bead’s case.
