Install the Sliding Shelf
Facing the rack, slide the shelf (item 7) onto the bottom surfaces of the
rail channels. The tabs at the back of the shelf pass underneath the
channel surface. The tabs allow you to extend the shelf from the cabinet,
thus providing a working surface for mounting the instruments.

Install Instruments on the Shelf
The L4400 instruments can be installed flush (even) with front edge of
the shelf, recessed in 50 mm increments, or reverse- mounted with the
front of the instrument facing the back of the rack cabinet.
1. Extend the shelf from the rack such that approximately 50% - 75% of
the shelf surface is outside of the rack. (The tabs on the back of the
shelf that run underneath the rail channel prevent the shelf from
tipping.)
2. Determine the position of the instruments (flush, recessed, reversed).
To accommodate the terminal blocks (available with some of the L4400
instruments) and to simplify cable routing, it is recommended that the
instruments be mounted flush (even) with the front or back edge of the
shelf.
3. Note the location of the four mounting holes on the bottom of the
instrument (Figure 1- 1). Set the carrier on the shelf, and align the
mounting holes with the holes on the shelf. Insert four M4x8 flat head
screws (item 1) upward through the bottom of the shelf and into the
carrier mounting holes.
