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.

WARNING: 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.

Informations sur l’utilisation de cet équipement en environnements dangereux.

Les produits marqués "CL I, DIV 2, GP A, B, C, D" ne conviennent qu'à une utilisation en environnements de Classe I Division 2 Groupes A, B, C, D dangereux et non dangereux. Chaque produit est livré avec des marquages sur sa plaque d'identification qui indiquent le code de température pour les environnements dangereux. Lorsque plusieurs produits sont combinés dans un système, le code de température le plus défavorable (code de température le plus faible) peut être utilisé pour déterminer le code de température global du système. Les combinaisons d'équipements dans le système sont sujettes à inspection par les autorités locales qualifiées au moment de l'installation.

AVERTISSEMENT: Risque d’Explosion –

•Couper le courant ou s'assurer que l'environnement est classé non dangereux 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.

Module Installation

Compact I/O is suitable for use in an industrial environment when installed in accordance with these instructions.

Prevent Electrostatic Discharge

ATTENTION: Electrostatic discharge can damage integrated

circuits or semiconductors if you touch bus connector pins or the terminal block. Follow these guidelines when you handle the module:

• Touch a grounded object to discharge static potential.

• Wear an approved wrist-strap grounding device.

• Do not touch the bus connector or connector pins.

• Do not touch circuit components inside the module.

• Use a static-safe work station, if available.

• When not in use, keep the module in its static-shield box.

Remove Power

ATTENTION: Remove power before removing or inserting this

module. When you remove or insert a module with power applied, an electrical arc may occur. An electrical arc can cause personal injury or property damage by:

• sending an erroneous signal to your system’s field devices, causing unintended machine motion.

• causing an explosion in a hazardous environment.

Electrical arcing causes excessive wear to contacts on both the module and its mating connector. Worn contacts may create electrical resistance.

System Assembly

The module can be attached to the controller or an adjacent I/O module before or after mounting.

• For mounting instructions, see Panel Mounting

Mounting on page 11.

• To work with a system that is already mounted, see Replacing a Single

Module Within a System on page 11.

The following procedure shows you how to assemble the Compact I/O system.

1. Disconnect power.

2. Check that the bus lever of the module to be installed is in the unlocked

(fully right) position.

3. Use the upper and lower tongue-and-groove slots (1) to secure the

modules together (or to a controller).

4. Move the module back along the tongue-and-groove slots until the bus

connectors (2) line up with each other.

5. Push the bus lever back slightly to clear the positioning tab (3). Use your

fingers or a small screwdriver.

6. To allow communication between the controller and module, move the

bus lever fully to the left (4) until it clicks. Make sure it is locked firmly in place.

ATTENTION: When attaching I/O modules, it is very important that the bus connectors are securely locked together for proper electrical connection.

7. Attach an end cap terminator (5) to the last module in the system by

using the tongue-and-groove slots as before.

8. Lock the end cap bus terminator (6).

IMPORTANT

A 1769-ECR or 1769-ECL right or left end cap must be used to terminate the end of the serial communication bus.

Mounting Expansion I/O

ATTENTION: During panel or DIN rail mounting of all devices, be

sure that all debris, such as metal chips or wire strands, is kept from falling into the module. Debris that falls into the module could cause damage on power up.
