Important User Information
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. Because of this difference, and also because of
the wide variety of uses for solid-state equipment, all persons responsible for applying this equipment
must satisfy themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or consequential damages
resulting from the use or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the

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 5V A 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 EN/IEC 60529, as applicable, for explanations of the
degrees of protection provided by enclosures.
ATTENTION: Read this document and the documents listed in the Additional
Resources section about installation, configuration, and operation of this
equipment before you install, configure, operate, or maintain this product. Users
are required to 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 are required to 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.

FLEX I/O 220V AC Digital Input and Output Modules
Prevent Electrostatic Discharge
Special Conditions for Safe Use
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:
• 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. Refer to Industrial Automation Wiring and Grounding Guidelines,
publication 1770-4.1, for more information.
• Do not remove or replace an Adapter Module while power is applied.
Interruption of the backplane can result in unintentional operation or
machine motion.
• Do not remove or replace a terminal base unit while power is applied.
Interruption of the backplane cab 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.

FLEX I/O 220V AC Digital Input and Output Modules
Electrical Safety Considerations
WARNING:
• When 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.
Repeated electric arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical resistance that
can affect module operation.
• 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.
ATTENTION:
• This equipment is certified for use only within the surrounding air temperature
range of 0…55 °C (32…131 °F). The equipment must not be used outside of
this range.
• Use only a soft dry anti-static cloth to wipe down equipment. Do not use any
cleaning agents.
At the end of its life, this equipment should be collected separately from any
unsorted municipal waste.

output device to the corresponding odd-numbered terminal (C-1, 3, 5,
7, 9, 11, 13, or 15) on row (C) as indicated in the Wiring Connections
for 1794-IM8 and 1794-OM8 table. (The 220V L2 commons of odd-
numbered terminals on row (C) are internally connected together.)
3. Connect 220V AC power (L1) to terminal 34 on the row (C).
4. Connect 220V AC common (L2) to terminal 16 on the row (B).
5. If daisychaining L1 power to the next terminal base, connect a jumper
from terminal 51 (220V AC L1) on this base unit to terminal 34 on the
next base unit.
