Cabling and Compliance Requirements
For FCC Part 15 Class A compliance for EMI/RFI suppression, the Broadmore 1750
requires that a ferrite bead (P/N 010-0051) must be attached to each DC power cable,
Ethernet cable, and alarm cable. FCC compliance also requires that an EMI cable be
attached between the chassis and air de flector. Accessory kits are included with the
Broadmore chassis. Use the following guidelines for FCC compliance.
DC power, one or two cables. Attach one ferrite bead to each cable, using a single
wrap so that the cable passes through the bead twice (see figure below left).
Ethernet, one o r two cabl es. Atta ch one fe rrite bead to each cable, using a single
wrap so that the cable passes through the bead twice.
Alarm cable. Attach one ferrite bead to the cable, using a single wrap so that the
cable passes through the bead twice.
EMI cable. The EMI cable must be attached vertically acros s the bottom rear
opening (see figure below right). Remove the existing screw at the top center of
the air deflecto r at the rear of the unit. Discard the existing flat washer. Using the
existing screw, attach the ring terminal of the EMI cable to the air deflector.
Attach the ground clip to the other end of the EMI cable. Attach the ground clip
