SHOCK HAZARD: Labels may be on or inside the equipment (for example, drive or
motor) to alert people that dangerous voltage may be present.
BURN HAZARD: Labels may be on or inside the equipment (for example, drive or
motor) to alert people that surfaces may reach dangerous temperatures.
Identifies information that is critical for successful application and understanding of
the product.
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 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 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:
• 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.
POINT I/O 2 and 4 Relay Output Modules 3
Preventing 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.

European Hazardous Location Approval
European Zone 2 Certification (The following applies when the product bears the
Ex Marking)
This equipment is intended for use in potentially explosive atmospheres as defined by
European Union Directive 94/9/EC.
DEMKO certifies that this equipment has been found to comply with the Essential Health and
Safety Requirements relating to the design and construction of Category 3 equipment
intended for use in Zone 2 potentially explosive atmospheres, given in Annex II to this
Directive.
Compliance with the Essential Health and Safety Requirements has been assured by
compliance with EN 60079-15.
ATTENTION: This equipment is not resistant to sunlight or other sources of
UV radiation.
ATTENTION: POINT I/O 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.
WARNING: This equipment must be installed in an enclosure providing at least
IP54 protection when applied in Class I, Zone 2 environments.
WARNING: This equipment shall be used within its specified ratings defined
by Rockwell Automation.
WARNING: Provision shall be made to prevent the rated voltage from being
exceeded by transient disturbances of more than 40% when applied in Class I,
Zone 2 environments.
WARNING: Do not disconnect equipment unless power has been removed or
the area is known to be nonhazardous.
WARNING: Exposure to some chemicals may degrade the sealing properties of
materials used in the following devices:
Relay K2 and K4, Epoxy for 1734-OW2, and Relay K1 through K4, Epoxy for
1734-OW4.
It is recommended that the User periodically inspect these devices for any
degradation of properties and replace the module if degradation is found.

ATTENTION: The power supply voltage may be daisychained from a 1734
adapter, 1734-FPD or 1734-EP24DC communication interface. Each channel is
individually isolated and may have a unique supply and/or voltage as necessary.
ATTENTION: Do not attempt to increase load current or wattage capability
beyond the maximum rating by connecting two or more outputs in parallel. The
slightest variation in relay switching time may cause one relay to momentarily
switch the total load current.
ATTENTION: Make sure that all relay wiring is properly connected before
applying any power to the module.
ATTENTION: Total current draw through the wiring base unit is limited to 10 A.
Separate power connections to the terminal base unit may be necessary.
ATTENTION: Use the end cap from your adapter or interface module 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.
