General wiring standards
To achieve reliable operation of the UCC MMI-2 the following should be observed:
All signal cables
MUST
be screened and all cable screens should be connected electrically to the cable connector's metal shells.
It is recommended that cable screens should only be connected to the functional earth (via the connector shell) of the UCC MMI-2. To avoid
earth loops, cable screens should not be directly attached to the CMM's functional earth.
The grounding must be continuous between all equipment in the installation.
All cable connectors should be secured to the UCC MMI-2 by the connector jack screws (where present).
NOTE:
The UCC MMI-2 electronics 0 V rail is connected to the system grounding scheme at a star point within the UCC MMI-2.
