Environment and Enclosure
Preventing Electrostatic Discharge
ATTENTION: This equipment is intended for use in a Pollution Degree 2
industrial environment, in overvoltage Category II applications (as defined in
IEC 60664-1), at altitudes up to 2000 m (6562 ft) without derating. This
equipment is not intended for use in residential environments and may not
provide adequate protection to radio communication services in such
environments.
This equipment is supplied as open-type equipment. It must be mounted
within an enclosure that is suitably designed for those specific
environmental conditions that will be present and appropriately designed to
prevent personal injury resulting from accessibility to live parts. The
enclosure must have suitable flame-retardant properties to prevent or
minimize the spread of flame, complying with a flame spread rating of 5VA
or be approved for the application if nonmetallic. The interior of the
enclosure must be accessible only by the use of a tool. Subsequent sections
of this publication may contain additional information regarding specific
enclosure type ratings that are required to comply with certain product
safety certifications.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, Rockwell
Automation publication 1770-4.1, for additional installation requirements.
• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the
degrees of protection provided by different types of enclosure.
ATTENTION: This equipment is sensitive to electrostatic discharge, which
can cause internal damage and affect normal operation. Follow these
guidelines when you handle this equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in use.

WARNING:
•When used in a Class I, Division 2, hazardous location, this equipment must
be mounted in a suitable enclosure with proper wiring method that
complies with the governing electrical codes.
•If you connect or disconnect the serial cable with power applied to this
module or the serial device on the other end of the cable, an electrical arc
can occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before
proceeding.
•If you connect or disconnect the communications cable with power applied
to this module or any device on the network, an electrical arc can occur. This
could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before
proceeding.
•The local programming terminal port is intended for temporary use only and
must not be connected or disconnected unless the area is assured to be
nonhazardous.
•The USB port is intended for temporary local programming purposes only
and not intended for permanent connection. If you connect or disconnect
the USB cable with power applied to this module or any device on the USB
network, an electrical arc can occur. This could cause an explosion in
hazardous location installations. Be sure that power is removed or the area
is nonhazardous before proceeding.
The USB port is a nonincendive field wiring connection for Class I, Division2
Groups A, B, C and D.
•Exposure to some chemicals may degrade the sealing properties of
materials used in the Relays. It is recommended that the User periodically
inspect these devices for any degradation of properties and replace the
module if degradation is found.
•If you insert or remove the plug-in module while backplane power is on, an
electrical arc can occur. This could cause an explosion in hazardous location
installations. Be sure that power is removed or the area is nonhazardous
before proceeding.
Refer to the Wiring Diagram for each plug-in module for additional details
regarding removal or insertion under power
•When you change switch settings while power is on, an electrical arc can
occur. This could cause an explosion in hazardous location installations.

If you would like a manual, you can:
• download a free electronic version from the Internet:
http://rockwellautomation.com/literature
• purchase a printed manual by contacting your local Allen-Bradley distributor or
Rockwell Automation representative
ATTENTION:
•Electrostatic discharge can damage semiconductor devices inside the
module. Do not touch the connector pins or other sensitive areas.
•Do not remove the protective debris strips until after the controller and all
other equipment in the panel near the module are mounted and wired.
Remove strips before operating the controller. Failure to remove strips
before operating can cause overheating.
•Be careful when stripping wires. Wire fragments that fall into the controller
could cause damage. Once wiring is complete, make sure the controller is
free of all metal fragments.

Status Indicator
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.

10 Micro850 48 Point Programmable Controllers
Publication 2080-IN008C-EN-P - August 2017
Module Spacing
Maintain spacing from objects such as enclosure walls, wireways and adjacent equipment. Allow
50.8 mm (2 in.) of space on all sides for adequate ventilation. If optional accessories/modules are
attached 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 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 are finished wiring the controller and
any other devices.
TIP
For environments with greater vibration and shock concerns, use the panel
mounting method, instead of DIN rail mounting.

Panel Mounting Dimensions
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 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.
