Introduction to the L4400 Series LXI Instruments 1

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.
