ATTENTION: Make sure you understand the anti-static environment.
The processor is shipped in a static-shielded container to guard against electrostatic damage. Electrostatic discharge can damage integrated circuits or semiconductors in the processor module if you touch backplane connector pins. It can also damage the module when you set configuration plugs or switches inside the module. Avoid electrostatic damage by observing the following precautions.
• Remain in contact with an approved ground point while handling the module (by wearing a properly grounded wrist strap).
• Do not touch the backplane connector or connector pins.
• When not in use, keep the module in its static-shielded container.

- an I/O chassis backplane fault occurs
- you select program or test mode
- you set a status file bit to reset a local rack
` If an EEPROM module is not installed and processor memory is valid, the processor's PROC LED indicator blinks,
and the processor sets S:11/9, bit 9 in the major fault status word. To clear this fault, change the processor from
program mode to run mode and back to program mode.
´ If the processor's keyswitch is set in REMote, the processor enters remote RUN after it powers up and has its
memory updated by the EEPROM module.

The following instructions are general. For specific information, see the documentation set for your particular software package.
Before you install your programming software, make certain you meet the system requirements for that software – sufficient disk space, memory, etcetera. Then, follow the procedures outlined in the software documentation to install the software and configure communication.
Start the programming software by following the procedures described in your programming software documentation.
If you have difficulty, verify that the power supply is turned on.
To monitor your system as you configure and run it, check the processor LED display for the following indicators:

Power Up the System
Power up the system if you have not done so already. Check the LED display on the processor. If your system is operating properly, the
PROC LED should be steady red and the message
“Processor RAM is faulted. Press <Enter> to clear memory” should appear on the display. See the following table to proceed. If the PROC LED is not red, turn to chapter 4 for troubleshooting information.
If your keyswitch is in this position:

The software is in Remote Program mode.
You see the message “ No access or privilege violation ” because you cannot clear memory in Run mode. Change the keyswitch position to Program or Remote and press <Enter> to clear memory.

CSA Hazardous Location Approval
Approbation d’utilisation dans des emplacements dangereux par la
CSA
CSA certifies products for general use as well as for use in hazardous locations. Actual CSA certification is indicated by the product label as shown below, and not by statements in any user documentation.
La CSA certifie les produits d’utilisation générale aussi bien que ceux qui s’utilisent dans des emplacements dangereux. La certification CSA en vigueur est indiquée par l’étiquette du produit et non par des affirmations dans la documentation à l’usage des utilisateurs.

To comply with CSA certification for use in hazardous locations, the following information becomes a part of the product literature for
CSA-certified Allen-Bradley industrial control products.
• This equipment is suitable for use in Class I, Division 2,
Groups A, B, C, D, or non-hazardous locations only.
• The products having the appropriate CSA markings (that is, Class I
Division 2, Groups A, B, C, D), are certified for use in other equipment where the suitability of combination (that is, application or use) is determined by the CSA or the local inspection office having jurisdiction.
Important: Due to the modular nature of a PLC control system, the product with the highest temperature rating determines the overall temperature code rating of a PLC control system in a Class I, Division
2 location. The temperature code rating is marked on the product label as shown.
Pour satisfaire à la certification de la CSA dans des endroits dangereux, les informations suivantes font partie intégrante de la documentation des produits industriels de contrôle Allen-Bradley certifiés par la CSA.
• Cet équipement convient à l’utilisation dans des emplacements de
Classe 1, Division 2, Groupes A, B, C, D, ou ne convient qu’à l’utilisation dans des endroits non dangereux.
• Les produits portant le marquage approprié de la CSA (c’est à dire,
Classe 1, Division 2, Groupes A, B, C, D) sont certifiés à l’utilisation pour d’autres équipements où la convenance de combinaison (application ou utilisation) est déterminée par la CSA ou le bureau local d’inspection qualifié.
Important: Par suite de la nature modulaire du système de contrôle PLC, le produit ayant le taux le plus élevé de température détermine le taux d’ensemble du code de température du système de contrôle d’un PLC dans un emplacement de Classe 1, Division 2. Le taux du code de température est indiqué sur l’étiquette du produit.

The following warnings apply to products having CSA certification for use in hazardous locations.
!
ATTENTION: Explosion hazard –
• Substitution of components may impair suitability for Class I, Division 2.
• Do not replace components unless power has been switched off or the area is known to be non-hazardous.
• Do not disconnect equipment unless power has been switched off or the area is known to be non-hazardous.
• Do not disconnect connectors unless power has been switched off or the area is known to be non-hazardous. Secure any user-supplied connectors that mate to external circuits on an
Allen-Bradley product using screws, sliding latches, threaded connectors, or other means such that any connection can withstand a 15
Newton (3.4 lb.) separating force applied for a minimum of one minute.
Les avertissements suivants s’appliquent aux produits ayant la certification
CSA pour leur utilisation dans des emplacements dangereux.
!
AVERTISSEMENT: Risque d’explosion –
• La substitution de composants peut rendre ce matériel inacceptable pour les emplacements de Classe I,
Division 2.
• Couper le courant ou s’assurer que l’emplacement est désigné non dangereux avant de remplacer les composants.
• Avant de débrancher l’équipement, couper le courant ou s’assurer que l’emplacement est désigné non dangereux.
• Avant de débrancher les connecteurs, couper le courant ou s’assurer que l’emplacement est reconnu non dangereux. Attacher tous connecteurs fournis par l’utilisateur et reliés aux circuits externes d’un appareil
Allen-Bradley à l’aide de vis, loquets coulissants, connecteurs filetés ou autres moyens permettant aux connexions de résister à une force de séparation de 15 newtons (3,4 lb. - 1,5 kg) appliquée pendant au moins une minute.
