OUTPUT CONTACT RATING The 469 case, alone or adjacent to another SR series unit, can be installed in the panel of a standard 19-inch rack (see the diagram below for panel cutout dimensions). Provision must be made when mounting for the front door to swing open without interference to, or from, adjacent equipment.

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.
