UCC T5 general wiring standards

To achieve reliable operation of the UCC T5 and the CMM's host computer, the following points should be observed:

  • All signal cables MUST be screened and all cable screens must be connected electrically to the metal shells of the cable connectors
  • It is recommended that cable screens should only be connected to the protective earth (via the connector shell) of the UCC T5 and SPA3-2
  • To avoid earth loops, cable screens should not be directly attached to the CMM's protective earth
  • The protective grounding must be continuous between the controller and all other equipment in the installation
  • All cable connectors should be secured to the UCC T5 and SPA3-2 by the connector jack screws

NOTE: The UCC T5 and SPA3-2 electronic zero volt rails are connected to their respective ground planes at star points within the UCC T5, the SPA3-2 and also to the protective ground of the ac supply.
