DESCRIPTION
The SR469 is packaged in the standard 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, such as automatic CT shorting. The
unit is mechanically held in the case by pins on the locking handle, which cannot be fully lowered to the locked position until the electri-
cal connections are completely mated. Any SR469 can be installed in any SR469 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, but it can be cleaned with a damp cloth.

Figure 2-2 SEAL ON DRAWOUT UNIT
To prevent unauthorized removal of the drawout unit,
a wire lead seal can be installed in the slot provided
on the handle as shown in Figure 2-2. 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 still allow monitoring of
actual values. If access to the front panel controls
must be restricted, a separate seal can be installed
on the outside of the cover to prevent it from being
opened.
** WARNING ** Hazard may result if the product is not used for its intended purpose.
