Hardware Reference Guide - NX-Series NetLinx Integrated Controllers
Mounting the Controller
Use the rack-mounting brackets (supplied with the NX-2200/3200/4200) for equipment rack installations.
Remove the mounting brackets and apply the rubber feet to the bottom of the controller for flat surface
installations.
Installing the Controller into an Equipment Rack
The NX-2200/3200/4200 each ship with removable rack ears for installation into an equipment rack. The
following instructions apply to the NX-2200/3200/4200.
Rack Mount Safety Instructions
Be sure to follow these important safety instructions when installing your central controller:
If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum ambient temperature
60°C (140°F).
Installing the equipment in a rack should be such that the amount of air flow required for safe
operation of the equipment is not compromised.
Mounting the equipment in the rack should be such that a hazardous condition is not achieved due
to uneven mechanical loading.
Consideration should be given to the connection of the equipment to the supply circuit and the
effect that overloading of the circuits might have on over current protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when addressing this
concern.
Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be
given to supply connections other than direct connections to the branch circuit (e.g. use of power
strips).
Note:
To avoid repeating the installation, test the incoming wiring by connecting the Controller’s connectors
to their terminal locations and applying power. Verify that the unit is receiving power and functioning
properly. Disconnect the terminal end of the power cable from the connected 12 VDC-compliant power supply.
1.
Use the supplied #8-32 screws to secure the rack ears to the sides of the controller. You can attach the rack
ears toward the front or rear panel for either a front-facing or rear-facing installation.
2.
Slide the unit into the rack until the attachment holes, along both sides, align to their corresponding
locations on the mounting brackets, as shown in FIG. 6.

3.
Thread the cables through the opening in the equipment rack. Allow for enough slack in the cables to
accommodate for movement during the installation process.
4.
Reconnect all cables to their appropriate source/terminal locations. Refer to the
section on page 19 for more detailed wiring and connection information. Verify that the
terminal end of the power cable is not connected to the power supply before plugging in the 2-pin power
connector (or AC power connector on the NX-4200.)
