1.15 Ferrite Installation

Place third-party ferrites on certain cables to dampen electromagnetic interference (EMI) from the ONS
15454. Ferrites must be added to meet the requirements of GR 1089. Refer to the ferrite manufacturer
documentation for proper use and installation of the ferrites. The following illustrations show possible
ferrite placements on the ONS 15454 for power cables, AMP Champ connectors, baluns, BNC/SMB
connectors, and the wire-wrap pin field.

Procedure: Attach Ferrites to Power Cabling

Use a single oval ferrite TDK ZCAT2035-0930 for both pairs of cables and a block ferrite Fair Rite
0443164151 for each pair of cables.
Wrap the cables once around and through the block ferrites and pull the cable straight through the oval
Step 1
ferrites.
Place the oval ferrite between the ONS 15454 and the block ferrite as shown in
Step 2
Place the oval ferrite as close to the power terminals as possible and place the block ferrite within 5 to
Step 3
6 inches of the power terminals.
