Chapter 3 Install Your Controller

Module Spacing
Maintain spacing from enclosure walls, wireways, and adjacent equipment. Allow
50.8 mm (2 in.) of space on all sides. This provides ventilation and electrical
isolation. If optional accessories/modules are attached to the controller, such as
the power supply 2080-PS120-240VAC or expansion I/O modules, make sure
that there is 50.8 mm (2 in.) of space on all sides after attaching the optional
parts.
DIN Rail Mounting
The module can be mounted using the following DIN rails: 35 x 7.5 x 1 mm and
35 x 15 mm (EN 50 022 - 35 x 7.5 and EN 50 022 - 35 x 15).
TIP For environments with greater vibration and shock concerns, use the
panel mounting method, instead of DIN rail mounting.
Before mounting the module on a DIN rail, use a flat-blade screwdriver in the
DIN rail latch and pry it downwards until it is in the unlatched position.
1. Hook the top of the DIN rail mounting area of the controller onto the
DIN rail, and then press the bottom until the controller snaps onto the
DIN rail.
2. Push the DIN rail latch back into the latched position.
Use DIN rail end anchors (Allen-Bradley part number 1492-EAJ35 or
1492-EAHJ35) for vibration or shock environments.
To remove your controller from the DIN rail, pry the DIN rail latch downwards
until it is in the unlatched position.
Panel Mounting
The preferred mounting method is to use four M4 (#8) screws per module. Hole
spacing tolerance: ±0.4 mm (0.016 in.).
Follow these steps to install your controller using mounting screws.
1. Place the controller against the panel where you are mounting it. Make sure
the controller is spaced properly.
2. Mark drilling holes through the mounting screw holes and mounting feet
then remove the controller.
3. Drill the holes at the markings, then replace the controller and mount it.
Leave the protective debris strip in place until you are finished wiring the
controller and any other devices.
