Description

The 469 is packaged in the standard GE Multilin 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.
FIGURE 3–1: Dimensions
To prevent unauthorized removal of the drawout unit, a wire lead seal can be
installed in the slot provided on the handle. With this seal in place, the drawout unit
cannot be removed. A passcode or setpoint access jumper can be used to prevent
