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 EN/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 more 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 1770-4.1, for additional installation requirements.
• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the degrees of protection provided by enclosures.
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.
WARNING: If you connect or disconnect wiring while the field side 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.
ATTENTION: 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, Rockwell Automation publication 1770-4.1, for more
information.
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: Do not substitute a 1794-IF4I or 1794-IF4IXT with the 1794-IF4ICFXT, as this will force a remapping of IO and configuration data.
ATTENTION: Personnel responsible for the application of safety-related programmable electronic systems (PES) shall be aware of the safety
requirements in the application of the system and shall be trained in using the system.
ATTENTION: 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.

FLEX I/O-XT Isolated Analog Input Module Installation Instructions
Overview
The FLEX I/O-XT™ isolated analog input module mounts on a 1794 terminal base. In addition to the features supported by the 1794-IF4I and 1794-IF4IXT modules, the 1794-IF4ICFXT
features three additional parameters that allow additional control over the way the analog signals are processed by the module. The settings are at the module level.
Settings to these parameters affect all inputs set to 150 Hz, 300 Hz, or 600 Hz. The parameters do not affect channels set at 1200 Hz.

Status Indicator
The OK status indicator is bi-colored red and green. The indicator flashes green for any of the following three reasons:
• The module configuration word is zero (for example, power-up reset condition).
• The 24V DC user power is off.
• The module is in configuration mode.
The indicator displays red to indicate that the module did not pass the initial hardware test. Cycle the power.
After power-up, if the status indicator is not flashing green or solid green, cycle the module power to verify a proper reset of the bus interface.
