WARNING

Environment and Enclosure

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 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
requirements.

• NEMA Standard 250 and IEC 60529, as applicable, for explanations of
the degrees of protection provided by different types of enclosure.

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.

, for additional installation

When you connect or disconnect the Removable Terminal Block (RTB) with
field side power applied, 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.

Prevent Electrostatic Discharge

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.

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
protection provided by the equipment may be impaired.

To comply with UL restrictions, field power and all connected devices must be
powered from a single source compliant with the following:
Class 2.

Publication

To comply with the CE Low Voltage Directive (LVD), field power and all
connected I/O must be powered from a source compliant with the following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).

North American Hazardous Location Approval

The following information applies when
operating this equipment in hazardous
locations:

Products marked "CL I, DIV 2, GP A, B, C, D" are
suitable for use in Class I Division 2 Groups A, B, C, D,
Hazardous Locations and nonhazardous locations only.
Each product is supplied with markings on the rating
nameplate indicating the hazardous location
temperature code. When combining products within a
system, the most adverse temperature code (lowest
"T" number) may be used to help determine the overall
temperature code of the system. Combinations of
equipment in your system are subject to investigation
by the local Authority Having Jurisdiction at the time of
installation.

EXPLOSION HAZARD –

• Do not disconnect equipment
unless power has been removed
or the area is known to be
nonhazardous.

• Do not disconnect connections to
this equipment unless power h as
been removed or the area is
known to be nonhazardous.
Secure any external connections
that mate to this equipment by
using screws, sliding latches,
threaded connectors, or other

product.

• Substitution of components may
impair suitability for Class I,
Division 2.

• If this product contains batteries,
they must only be changed in an
area known to be nonhazardous.

If you connect or disconnect wiring while the field-side 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.

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.
