Base & Access
The base should be level and sufficiently firm to allow the stand to be bolted down. See
Appendix A for the required dimensions. Consider the following factors:
▪
The site should be readily accessible as the product weighs approximately 20 kg
(44 lb).
▪
There should be 2 m (79 in.) headroom.
▪
If a new concrete pad is required, the dimensions should be at least
610 mm (24 in.) long × 1220 mm (48 in.) wide × 90 mm (3 ½ in.) deep,
with an #3 (10 mm) steel reinforcing bar around the perimeter. This should be
grounded and bonded in accordance with local practice and code.
▪
The product should never be mounted directly to the transformer without first
consulting GE Technical Support.
▪
The intended AC supply is to be provided with a switch or circuit breaker so that it
can be independently de-energised. The location of the switch or circuit breaker
should be near the intended location of the product and within easy reach of the
operator.
If the GE manufactured mounting stand has not been purchased, a stand should be
constructed as outlined in Appendix A.
Communications & Power Cable Runs
If possible, communications and power cable runs from the intended product location to
their sources should be pre-installed. See Figure 5-1 for the general installation layout.
Bushing Adaptor Cable Runs
If possible, Bushing Adaptor cable runs from the intended product location to the
transformer bushings should be pre-installed. See Figure 5-1 for the general installation
layout.
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 −20 °C (−4 °F) to prevent damage to connectors and cabling because
they may become brittle at extreme low temperatures.

▪
Ensure that planned work complies with national and site regulatory
requirements.
▪
Ensure that any third-party equipment to be used is suitable and safe
before commencing work.
▪
Ensure that third parties have received appropriate training for
working at height. This includes, but is not limited to, 'Working at
