ATTENTION: This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in
EN 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 equipment. 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, 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 the following:
• Industrial Automation Wiring and Grounding Guidelines, Rockwell Automation publication 1770-4.1, for additional installation requirements
• NEMA 250 and EN 60529, as applicable, for explanations of the degrees of protection provided by different types of enclosures
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.
IMPORTANT For 1783-ETAP, 1783-ETAP1F, and 1783-ETAP2F modules running firmware revision 2.001 or later, DIP switch 3 is used to make the tap a ring
supervisor in a DLR network. To avoid adversely impacting communication in a linear or star network, take these precautions:
• Make sure switch 3 remains in the Off position. If switch 3 is in the On position, the tap will be automatically enabled as a ring supervisor.
• Make sure that the Ring Supervisor mode is not enabled in RSLinx
Classic software or the Studio 5000 Logix Designer
application.
When switch 3 is in the Off position, the programming software controls whether the tap is a ring supervisor.
