2 ControlNet Repeaters
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 60664-1), at altitudes up to 2000 m (6562 ft)
without derating.
This equipment is not intended for use in residential environments and may not provide adequate
protection to radio communication services in such environments.
This equipment is supplied as open-type equipment for indoor use. 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 or be approved for the application if nonmetallic. 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 the following:
• Industrial Automation Wiring and Grounding Guidelines, publication
installation requirements.
• NEMA Standard 250 and EN/IEC 60529, as applicable, for explanations of the degrees of protection
provided by enclosures.
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.
• If this equipment is used in a manner not specified by the manufacturer, the protection provided by
the equipment may be impaired.
• Before installing, configuring, operating, or maintaining this product, read this document and the
documents listed in the additional resources section for installing, configuring, or operating
equipment. Users should familiarize themselves with installation and wiring instructions in addition
to requirements of all applicable codes, laws, and standards.
• Installation, adjustments, putting into service, use, assembly, disassembly, and maintenance shall
be carried out by suitably trained personnel in accordance with applicable code of practice. In case of
malfunction or damage, no attempts at repair should be made. The module should be returned to
the manufacturer for repair. Do not dismantle the module.
• This equipment is certified for use only within the surrounding air temperature range of 0...60 °C
(32...140 °F). The equipment must not be used outside of this range.
• Solid state equipment has operational characteristics differing from those of electromechanical
equipment. Safety Guidelines for the Application, Installation, and Maintenance of Solid State
Controls, publication SGI-1.1, available from your local Rockwell Automation sales office, or online at
http://www.rockwellautomation.com/literature/, describes some important differences between
solid state equipment and hard-wired electromechanical devices.
• Use only a soft dry anti-static cloth to wipe down equipment. Do not use any cleaning agents.
ATTENTION: For fiber modules
• Under certain conditions, viewing the optical port may expose the eye to hazard. When viewed
under some conditions, the optical port may expose the eye beyond the maximum permissible
exposure recommendations.
• 1786-RPFS, 1786-RPFS: Class 1 LED; optical radiation is present during operation.
• 1786-RPFRL, 1786-RPFRXL: Class 1 laser; laser radiation is present when the system is open and
interlocks bypassed. Only trained and qualified personnel should be allowed to install, replace, or
service this equipment.
• Do not discard the end cap. 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.
Prevent 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 wrist strap.
• 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.

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.
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
