the ferrite assemblies supplied with the UPS as follows:
Serial Communications
Attach the smaller enclosed ferrite bead clamp to the communication cable as
shown in the drawing using the following directions:
• Open the ferrite bead.
• 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.

Attach the larger enclosed ferrite
bead clamp to the network cable as
shown in the drawing using the
following directions:
• Open the ferrite bead.
• Place the network cable inside the ferrite bead groove.
• Wrap the cable once around the bead.
• Position the ferrite cable as close as possible to the end of the cable that
