The unit case design facilitates quick access to the interior strappings as well as easy installation into a 19" rack.

F.3 Installation of the Unit Case into a 19" Rack

The height of the unit is 1U (1.75"); the width of the unit is slightly less than half the available mounting width. A rack adapter kit, RM-17, is available for installing either a single unit or two units side by side in the 19" rack.

Disconnect AC power before opening the unit.

Rack adapter components for installing a single unit include one short bracket and one long bracket. Each bracket is fastened to the side walls of the unit by two screws (with flat washers) which are inserted into the two front holes on the side wall (The unit is supplied with nuts already in place on the inner side wall). Note that the short bracket fastens to the left side of the unit, and the long bracket to the right side of the unit. See Figure F-1.

Once the brackets are fastened to the side walls, the unit is ready for installation in the 19" rack. Place the unit in the rack and fasten the brackets to the side rails of the rack by means of the two screws situated on each side (not included in the kit).
