Fixed Rackmount Adapters
Refer to Figure 2 while performing the following instructions.
1. Remove the four 6-32 x 1/4” screws on each side securing the cover near the front of the
instrument (eight screws total).
2. Remove the front two rubber feet mounted on the right side. They are attached by adhesive; it
may be necessary to carefully slide a thin blade between them and the panel.
3. Attach the two fixed rackmount adapters (items 1 and 2), using the 6-32 x 5/16” flathead screws
and the 10-32 x 5/16” truss head screws (item 4) from the kit. Note that there is a right and a
left bracket; the correct bracket will align with the front panel when installed.
4. Install the handles (item 6) on the rackmount adapters, using the 8-32 x 1/4” flathead screws
(item 3) from the kit. The handles should be positioned with their offset toward the center of
the instrument.
5. Install the instrument in your rack, using 10-32 screws (not supplied) to match your other
mounting hardware. Because of the weight of the instrument and depending on your rack
configuration, an assistant may be required.
6. Secure the rear of the rackmount adapters to the rack if desired. Because of the variety of rack
configurations, specific hardware and instructions are not supplied.

Slide-out Rackmount Adapters
Refer to Figure 1 while performing the following instructions.
Figure 1. Slide-out racknounting installation
Note: The components of the sliding rackmount assemblies are interchangeable. Two
right-hand assemblies are provided as standard components; one of them is simply
installed inverted on the left-hand side.
1. Remove the two 6-32 x 1/4” screws on each side securing the covers nearest the front panel of the
instrument.
2. Install the two rack ear brackets (items 1 and 2), using the 6-32 x 5/16 screws (item 3) from the kit.
Note that there is a right and a left bracket. The correct bracket will have its cutout section toward
the lower part of the instrument when installed. OBSERVE THE WARNING on the figure above.
3. Install the handles (item 6) on the rack ear brackets, using the 8-32 x 1/4” flathead screw (item 7)
from the kit. Note that the handles should be positioned with their offset toward the center of the
instrument.
4. Attach the sections of the rackmount adapters (item 5) to the instrument as shown in Figure 1,
using the rackmount slide spacers (item 8) and 10-32 x 5/16” truss head screws (item 4) from the
kit.
5. Install the stationary section of the sliding assemblies, along with their intermediate sections, in the
desired position in the rack. The top of their front mounting brackets will be approximately 2-1/4
inches (5.7 cm) below the intended top of the instrument when installed.
6. With the intermediate section fully inserted into the stationary rack sections, adjust the distance
between outside surfaces of the stationary rails to be 17-5/8 inches (44.4 cm).
7. Secure the rear of the rack sections, adjusting the distance between them to be the same as
measured in step 6. Universal mounting brackets are provided to address a wide range of rack
configurations.
8. Fully extend the intermediate sections of the sliding assemblies and confirm that they lock into
position.
9. Install the instrument onto the rack sliders, press in the lock buttons, and slide it into the rack.
10. Secure the rack ear brackets to the rack with four 10-32 screws (not supplied) to match the other
mounting screws in your rack.
WARNING!
These rack ear brackets should be
used only to pull the instrument
out on its sliders. They should not
be used to support the weight of
the instrument in the rack.
NOTE:
The rackmounted sections of the
sliding assemblies are not shown.
