Section 2.2.5 Grounding
3BSE 002 415R701 Rev A 2-21
Not CE-marked Design
If a conventional cabinet is used the attachment of the cable shield and anchoring of the cable is
co-ordinated by using the horizontal mounting bar, see Figure 2-9. The shield of a category A
cable must furthermore be run all the way up to the relevant connection unit. A suitable point of
grounding in the connection unit is shown in Figure 2-8. Use a short lead
≤
50 mm and thread-
cutting screws.
Shielded cables of the category A which are grounded locally at the transducer shall be left
ungrounded in a cabinet which is not CE-marked.
After anchoring and grounding of a category B cable shield in the horizontal mounting bar you
are free to cut the shield wherever it is most practical.
2.2.5.5 Grounding of Communication Cable Shields
General
Communication cables shall be routed directly to the actual connection unit, modem or
communication module in a subrack. Never open up a cable shield when entering the cabinet.
The grounding of the shield to the chassis, directly or via a capacitor is normally determined by
the type of communication. You must reflect the whole installation of the communication bus to
comply with a main rule: A bus communication cable shield must be directly grounded but only
in one end of the bus. That is in the cabinet where the first/last connected Advant Controller (or
other node) is located.
There is a supplement to the installation information given in separate communication user’s
guides.
