ATTENTION

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 publication 60664-1), at altitudes up to 2000 meters 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 el ec t ro mag n e tic 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 encl o su re t h at is su itably designed for those specific environmental conditions that will be present and appropriately designed to prevent personal injury resulting from accessibility to live parts. 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 require d to comply wit h certain product safety certifications.

See NEMA Standards publication 250 and IEC publication 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosure. Also, see the appropriate sections in this publication, as well as the Allen-Bradley publication 1770-4.1 ("Industrial Automation Wiring and Grounding Guidelines"), for additional installation requirements pertaining to this equipment.

ATTENTION

Publication 1734-IN587B-EN-P - March 2002

POINT I/O is grounded through the DIN rail to chassis ground. Use zinc plated, yellow chromated steel DIN rail to assure proper grounding. Using other DIN rail materials (e.g. aluminum, plastic, etc.) which can corrode, oxidize or are poor conductors can result in improper or intermittent platform grounding.

WARNING

ATTENTION

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 has 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 means provided with this 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.

Preventing Electrostatic Discharge

This equipment is sensitive to electrostatic discharge, which can cause internal da mage 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.

• If a vailable, use a static-s af e workstatio n .

• When not in use, st o r e t h e equipmen t in

appropriate static-safe packaging.

Installing 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.

Installing the I/O Module

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

WARNING

1. Using a bladed screwdriver, rotate the keyswitch (2) 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.)

Publication 1734-IN587B-EN-P - March 2002

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.
