The GMC version requires an Allen-Bradley filter (catalog number SP-74102-006-01, -02, -03) or equivalent Roxburgh filter (catalog number MIF323-GS, or
MIF330-GS, or MIF375-GS respectively).
Mount the filter as close to the 1394 as possible. Isolate filtered conductors from unfiltered conductors. It is recommended to mount the filter to the right of the
axis modules to simplify routing of filtered (clean) and unfiltered (noisy) wiring. The load end of the filter is considered noisy and should be routed carefully
away from clean signal wires.

360 shield termination for system module cables at the enclosure is required only for the GMC version. The termination for axis module cables are required
for all versions of the 1394. Use Wieland Electric commercial clamps or equivalent.

The filter shown is sized for one 1394. Equivalent filters may be used for multiple units. Size the filter following the manufacturers recommendation.

Ground bar is customer-supplied item for all Series A and B systems. Ground bar is included on all Series C systems.
I mportant: All three-phase power in the cabinet must be filtered to reduce EMI.
