FLEX I/O EtherNet/IP Adapters Installation Instructions
WARNING: Special Conditions for Safe Use:
• This equipment shall be mounted in an UKEX/ATEX/IECEx Zone 2 certified enclosure with a minimum ingress protection rating of at least IP54 (in accordance
with EN/IEC 60079-0) and used in an environment of not more than Pollution Degree 2 (as defined in EN/IEC 60664-1) when applied in Zone 2 environments.
The enclosure must be accessible only by the use of a tool.
• This equipment shall be used within its specified ratings defined by Rockwell Automation.
• Transient protection shall be provided that is set at a level not exceeding 140% of the peak rated voltage value at the supply terminals to the equipment.
• This equipment must be used only with UKEX/ATEX/IECEx certified Rockwell Automation backplanes.
• Secure any external connections that mate to this equipment by using screws, sliding latches, threaded connectors, or other means provided with this
product.
• Do not disconnect equipment unless power has been removed or the area is known to be nonhazardous.
• Earthing is accomplished through mounting of modules on rail.
Electrical Safety Considerations
ATTENTION: Power to this equipment and all connected I/O must be supplied from a source compliant with the following:
• SELV source approved to EN/IEC60950-1, EN/IEC61010-2-201 or EN/IEC62368-1 (ES1)
• PELV source approved to EN/IEC60950-1, EN/IEC61010-2-201 or EN/IEC62368-1 (ES1)
Note: A power source approved to a U.S.A. or Canadian version of the above listed standards is required for system approval in the U.S.A. or Canada.
ATTENTION: All wiring must comply with applicable electrical installation requirements (e.g., N.E.C. article 501-4(b)).
ATTENTION: Wire conductor and insulation ratings shall support minimum temperature rating of 85 °C (185 °F).
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 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.
ATTENTION: Special Conditions for Safe Use:
• This product is grounded through the DIN rail to chassis ground. Use zinc-plated chromate-passivated 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. Be sure to ground the DIN rail properly. See the
Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1, for more information.
• Do not remove or replace a terminal base unit while power is applied. Interruption of the backplane can result in unintentional operation or machine motion.
• Do not remove or replace an adapter while power is applied. Interruption of the backplane can result in unintentional operation or machine motion.
• If this equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
• To reduce susceptibility to noise, power analog modules and digital modules from separate power supplies.
WARNING:
• If you insert or remove the module while backplane power is on, an electric 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.
• If you connect or disconnect the communications cable with power applied to this module or any device on the network, an electric 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.
• If you connect or disconnect wiring while the field side 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.
• When used in a Class I, Division 2, hazardous location, this equipment must be mounted in a suitable enclosure with proper wiring method that complies with
the governing electrical codes.
• For Class I Division 2 applications, use only Class I Division 2 listed or recognized accessories and modules approved for use within the 1794 platform.
