Installation
The 469 is packaged in the standard GE Grid Solutions SR-series arrangement, which
consists of a drawout unit and a companion fixed case. The case provides mechanical
protection to the unit and is used to make permanent connections to all external
equipment. The only electrical components mounted in the case are those required to
connect the unit to the external wiring. Connections in the case are fitted with
mechanisms required to allow the safe removal of the relay unit from an energized panel
(for example, automatic CT shorting). The unit is mechanically held in the case by pins on
the locking handle that cannot be fully lowered to the locked position until the electrical
connections are completely mated. Any 469 can be installed in any 469 case, except for
custom manufactured units that are clearly identified as such on both case and unit, and
are equipped with an index pin keying mechanism to prevent incorrect pairings.
No special ventilation requirements need to be observed during the installation of the unit.
The 469 can be cleaned with a damp cloth.
