FOX615 Installation
1. Check the placement of the conductive foam (16) on the earthing bar
and cable clamp. Realign if appropriate.
2. Check the fit of the signal cables on the earthing bar. Realign if appropri-
ate.
3. Hook the left side of the clamp onto the notch (15) on the earthing bar
(21).
4. Rotate the right side of the clamp inward (22) onto the notch (14) on the
earthing bar until the spring bracket to the right snaps in.
5. Check both spring brackets for fit.
End of instruction
Follow the same steps mirrored to the left to reinstall the left side cable
clamp to its earthing bar.
Risk of operating trouble!
Attention to EMC properties!
When plugging units which are accessed with optical cables only, the con-
ductive foams in the cable clamp and in the earthing bar will be separated by
the insulated cables. The resulting gap impairs the specified EMC character-
istics.
→ ABB offers EMC clips providing an electrical connection between the
conductive foams in the cable clamp and in the earthing bar.
→ The EMC clips have to be pushed into the conductive foam of the
earthing bars to close the gap.
→ EMC clips have to be used where three or more units with optical
cables are plugged in adjacent slots.
→ Three evenly spaced EMC clips have to be used per earthing bar to
maintain the specified EMC characteristics of the FOX.
→ Please order the required amount of EMC clips at ABB.
