Environment and Enclosure

ATTENTION: This equipment is intended for use in a Pollution Degree 2

industrial environment, in overvoltage Category II applications (as defined in IEC
publication 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 Publication 11. Without appropriate precautions, there may be
potential difficulties ensuring electromagnetic compatibility in other
environments due to conducted as well as radiated disturbance.

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

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

, for additional installation requirements.

Preventing 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.

avant de débrancher l'équipement.

• Couper le courant ou s'assurer que
l'environnement est classé non dangereux
avant de débrancher les connecteurs.
Fixer tous les connecteurs externes reliés
à cet équipement à l'aide de vis, loquets
coulissants, connecteurs filetés ou autres
moyens fournis avec ce produit.

• La substitution de composants peut
rendre cet équipement inadapté à une
utilisation en environnement de Classe I,
Division 2.

• S'assurer que l'environnement est classé
non dangereux avant de changer les piles.

Install the Mounting Base

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

ATTENTION: This product 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 or 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.

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.

ATTENTION: Do not discard the end cap supplied with an adapter or
communication interface module.

Use this end cap to cover the exposed interconnections on the last mounting
base on the DIN rail. Failure to do so could result in equipment damage or injury
from electric shock.

Install the Module

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.

The module can be installed before or after base installation. Make sure that the mounting
base is correctly keyed before installing the module into the mounting base. In addition,
make sure the mounting base locking screw is positioned horizontal referenced to the base.

1. Using a bladed screwdriver, rotate the keyswitch on the mounting base clockwise
until the number required for the type of module being installed aligns with the
notch in the base.

2. Make certain the DIN rail locking screw is in the horizontal position. You cannot
insert the module if the locking mechanism is unlocked.

3. Insert the module straight down into the mounting base and press to secure. The
module locks into place.
