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 e 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, for
additional installation requirements, Allen-Bradley publication
1770-4.1.
• NEMA Standards 250 and IEC 60529, as applicable, for
explanations of the degrees of protection provided by different types of enclosure.

Combinations of equipment in your system are subject to investigation by the local Authority H aving Jurisdiction at the time of installation.
EXPLOSION HAZARD -
• Do not disconnect eq uipment 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
quipement en environnements dangereux:
é
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 marqua ges sur sa plaque d'identification qu i indiquent le code de température pour les environneme nts dangereux. Lorsque plusieurs produits sont combinés dans un système, le code de température le plus défavorable (co de de température le plus faible) peut être utilisé pour déterminer le code de température global du système. Les comb inaisons d'équipements dans le système sont sujettes à inspection par les autorités locales qualifiées au moment de l'installation.
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.

Preventing 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.

About the 1756-DHRIOXT Module

You can use the 1756-DHRIOXT module to communicate on a DH+ or remote I/O network.
The 1756-DHRIOXT module functions in the same way as the traditional 1756-DHRIO module. For information about configuring and using both the 1756-DHRIOXT and 1756-DHRIO module, see the ControlLogix Data Highway Plus-Remote I/O Communication Interface Module User Manual, publication
1756-UM514.

About ControlLogix-XT Systems

The ControlLogix-XT products include control and communication system components that, when used with FLEX I/O-XT products, provide a complete control system solution that can be used in environments where temperatures range from -20...70 °C (-4...158 °F).
When used independently, the ControlLogix-XT system can withstand
ironments where the temperature ranges from -25...70 °C
env (-13...158 °F).

ControlLogix-XT with Traditional ControlLogix Components

ControlLogix-XT system components are rated for extreme environmental conditions only when used properly with other Logix-XT system components. The use of ControlLogix-XT components
with traditional ControlLogix system components nullifies extreme-environment ratings.
If a ControlLogix-XT module is used with traditional ControlLogix products, that is, ControlLogix products not designed for extreme environments, the ControlLogix-XT module can withstand only the environments specified for the traditional ControlLogix version of the module. For example, if a 1756-DHRIOXT module is used in a traditional 1756-A10 chassis, the 1756-DHRIOXT module can withstand only the environment specified for the traditional 1756-DHRIO module.
The ControlLogix-XT system components are designed to meet the same
greater operational and environmental requirements as traditional
and ControlLogix products.
When a ControlLogix-XT component is traditional ControlLogix component, the functional and environmental requirements of the traditional ControlLogix component apply.

Before You Begin

Before you install your module, complete these tasks:
• Set the Network Type and Node Address Switches, page 10
• Prepare the Chassis for Module Installation, page 11
• Determine Module Slot Location, page 12

Set the Network Type and Node Address Switches

Before you install the module, set the network type switches for each channel.
If your module uses the 230k DH+ network, that is, Channel A switch set to 3, Channel B is disabled.
Also, node address switches do not apply if you are using remote I/O.
1. Using this image or the module label as a reference, set the netw
ork type switches on the top of the module.
