General wiring standards
To achieve reliable operation of the UCC BI 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 BI and
SPA2-2. 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 BI and SPA2-2 by the connector jack screws (where present).
NOTE: The UCC BI and SPA2-2 electronic zero volt rails are connected to their respective ground planes at star points within the UCC BI, the SPA2-2, and also to the protective ground of the SPA2-2 ac supply.
