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://literature.rockwellautomation.com) 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.

No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits, equipment, or software described in this manual.

Reproduction of the contents of this manual, in whole or in part, without written permission of Rockwell Automation, Inc., is prohibited.

Throughout this manual, when necessary, we use notes to make you aware of safety considerations.

ATTENTION
			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 considered Group 1, Class A industrial equipment according to IEC/CISPR 11. Without appropriate precautions, there may be difficulties with electromagnetic compatibility in residential and other environments due to conducted and radiated disturbances.

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, V2, V1, V0 (or equivalent) if non-metallic. 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.

WARNING			When you insert or remove the 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. Repeated electrical arcing causes excessive wear to
			contacts on both the module and its mating connector. Worn contacts may
			create electrical resistance that can affect module operation.

Prevent Electrostatic Discharge

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.

ATTENTION				POINT I/O is grounded through the DIN rail to chassis ground. Use zinc plated
				yellow-chromate steel DIN rail to assure proper grounding. The use of other
				DIN rail materials (for example, aluminum, plastic) that can corrode, oxidize, or
				are poor conductors, can result in improper or intermittent grounding.
				Secure DIN rail to mounting surface approximately every 200 mm (7.8 in.) and
				use end-anchors appropriately.
				If this equipment is used in a manner not specified by the manufacturer, the
ATTENTION
				protection provided by the equipment may be impaired.
				To comply with UL restrictions, field power and all connected devices must be
ATTENTION
				powered from a single source compliant with the following:
				Class 2.
				To comply with the CE Low Voltage Directive (LVD), field power and all
ATTENTION
				connected I/O must be powered from a source compliant with the following:
				Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).

Install the Mounting Base

To install the mounting base on the DIN rail, proceed as follows:

1.Position the mounting base vertically above the installed units (adapter, power supply or existing module).

2.Slide the mounting base down allowing the interlocking side pieces to engage the adjacent module or adapter.

3.Press firmly to seat the mounting base on the DIN rail. The mounting base will snap into place.

4.To remove the mounting base from the DIN rail, remove the module, and use a small bladed screwdriver to rotate the base locking screw to a vertical position. This releases the locking mechanism. Then lift straight up to remove.
