Rack Mount Installation
You can install the ACO-4400A into an equipment rack. It is recommended to loom the cables so
that they do not introduce extra weight or twisting force on the front panel rack mountings or rear
panel connectors. If installed in a mobile application, the rack mount kit is essential.
This section describes how to install the ACO-4400A into the rack.
Installing the ACO-4400A into a Rack Unit
The ACO-4400A mounts in the rack cabinet by means of four screws through the front mounting
flanges. This should normally be sufficient to carry the load, including weight of cables. Refer to
the
SRG-4400 Quick Start Guide for mounting details.
Installing the Rear Support Brackets
In some cases, (mobile trucks, etc.) it may be desirable to also support the rear of the
ACO-4400A. The rear support bars can be attached to the ACO-4400A in six possible positions.

Figure 2.1 )
Figure 2.1 Installing the Support Brackets
To install the support brackets
1. Choose the position that suits the cabinet depth and will give approximately a 0.5”
projection beyond the previously mounted bracket.
2. Using four screws per bracket (Ross P/N 2101-3005-RC), as shown in Figure 2.1 , attach
both bars.
3. Mount the frame to the front rails of the rack cabinet using rack screws.
4. At the rear of the cabinet, slide the bracket slots over the rear of the support bars and
secure to the cabinet rear rails with rack screws.
Warning
— To prevent the rack mounted ACO-4400A from tipping forward onto the operator,
install the instrument so that the operator will be able to access all of its rear-panel connectors
without pushing down on the instrument.
Warning
— Do not use the support brackets to carry the ACO-4400A. The brackets are not
primarily designed for this purpose, and property damage or personal injury may result.
