Important User Information

Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines

for the Application, Installation and Maintenance of Solid State Controls (Publication SGI-1.1 available from your local Rockwell

Automation sales office or online at http://rockwellautomation.com/literature) describes some important differences between

solid state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide

variety of uses for solid state equipment, all persons responsible for applying this equipment must satisfy themselves that each

intended application of this equipment is acceptable.

In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages resulting from the use

or application of this equipment.

The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables and

requirements associated with any particular installation, Rockwell Automation, Inc. cannot assume responsibility or liability for

actual use based on the examples and diagrams.

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

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.
