2 INSTALLATION 2.1 MECHANICAL
The 469 is packaged in the standard GE Power Management SR series arrangement, which consists of a dra-
wout 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 mecha-
nisms 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.
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 entry of setpoints but allow monitoring of actual values. If access to the front panel con-
trols must be restricted, a separate seal can be installed on the cover to prevent it from being opened.
Hazard may result if the product is not used for its intended purpose.
