General wiring standards
To achieve reliable operation of the UCC PI 80 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 PI 80. 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 PI 80 and SPA (where present) by the connector jack screws.
NOTE: When used for SP80 only, with an SPA3 and UCC S3, the amplifier ground will be connected to the UCC PI 80 ground through the UCC S3.
