Mount the Module
Most applications require installation in an industrial enclosure to reduce the effects of
electrical interference and environmental exposure. Locate your controller as far as possible
from power lines, load lines, and other sources of electrical noise such as hard-contact
switches, relays, and AC motor drives. For more information on proper grounding guidelines,
see the Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1.
Mounting Dimensions and DIN Rail Mounting
Module Spacing
Maintain spacing from objects such as enclosure walls, wireways and adjacent equipment.
Allow 50.8 mm (2.0 in.) of space on all sides for adequate ventilation. If optional

expansion I/O modules, make sure that there is 50 mm (1.97 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 mm x 1 mm
(EN 50 022 - 35 x 7.5).
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-EA35 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 have finished wiring any other
devices.
Use Surge Suppressors
Because of the potentially high current surges that occur when switching inductive load
devices, such as motor starters and solenoids, we recommend the use of some type of surge
TIP
For environments with greater vibration and shock concerns, use the panel
mounting method, instead of DIN rail mounting.

Micro850 24-Point Programmable Controllers 11
Publication 2080-IN007A-EN-P - September 2012
suppression to protect and extend the operating life of the controllers output contacts.
Switching inductive loads without surge suppression can significantly reduce the life expectancy
of relay contacts. By adding a suppression device directly across the coil of an inductive
device, you prolong the life of the output or relay contacts. You also reduce the effects of
voltage transients and electrical noise from radiating into adjacent systems.
Refer to the Micro830 and Micro850 Programmable Controllers User Manual, publication
2080-UM002, for suitable surge suppression methods and recommended surge suppressors.
Expansion I/O and Plug-In Module Installation
To attach expansion I/O and plug-in modules to your Micro850 controller, see the
installation manual and/or wiring diagrams specific to your plug-ins and expansion I/O.
Installation Instructions are available in the Literature Library,
