9.4.1
Bushing Adaptor Cables
Details of recommended conduit and fittings are listed in Appendix A.
The rubber O-rings must not be contaminated with grease during the
assembly process.
Both ends of the coaxial cables for the Bushing Adaptor and Neutral CT
must be prepared and fitted with pin terminals as described in Section
9.4.1.1.
All coaxial cables from the Bushing Adaptors to the product cabinet
must
be run inside a protective electrically grounded metal conduit. See
Appendix A.3 for recommended conduit and fittings.
If working at heights is required during the product installation, it is the
responsibility of the installer to ensure that:
▪
planned work complies with national and site regulatory requirements.
▪
third-party equipment is suitable and safe before commencing work.
▪
third parties have received appropriate training for working at height.
This includes, but is not limited to, ‘Working at height’ and ‘Using Mobile
Elevated Working Platforms’.
All coaxial cables from the Bushing Adaptors to the product cabinet must
be run inside a protective electrically grounded metal conduit.
All installation activity should take place in ambient temperatures greater
than
−10 °
C (14 °F) to prevent damage to connectors and cabling because
they may become brittle at extreme low temperatures.
When installing conduit to Bushing Adaptors, ensure that the conduit drops
away from the Bushing Adaptor body.
