UCC MMI-2 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.
