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
Prevent Electrostatic Discharge
ATTENTION: This equipment is intended for use in a Pollution Degree 2
industrial environment, in overvoltage Category II applications (as defined in
IEC publication 60664-1), at altitudes up to 2000 meters (6562 ft)
without derating.
This equipment is considered Group 1, Class A industrial equipment according
to IEC/CISPR Publication 11. Without appropriate precautions, there may be
potential difficulties ensuring electromagnetic compatibility in other
environments due to conducted as well as radiated disturbance.
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:
• Industrial Automation Wiring and Grounding Guidelines, for additional
installation requirements, Allen-Bradley publication 1770-4.1
.
• NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided by
different types of enclosure.
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.
4 POINT I/O 24V DC Expansion Power Supply
Publication 1734-IN058C-EN-P - October 2015
WARNING: When you insert or remove the module while backplane 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. Repeated electrical 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.
WARNING: If you connect or disconnect the communication cable with
power applied to this module or any device on the network, an electrical arc
can occur. This could cause an explosion in hazardous location installations.
ATTENTION: To comply with the CE Low Voltage Directive (LVD), field power
and all connected I/O must be powered from a source compliant with the
following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).
ATTENTION: If this equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be impaired.
ATTENTION: To comply with UL restrictions, field power and all connected
devices must be powered from a single source compliant with the following:
Class 2.
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, 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.

POINT I/O 24V DC Expansion Power Supply 7
Publication 1734-IN058C-EN-P - October 2015
About the Power Supply
The expansion power supply passes 24V DC field power to the I/O modules to the right
of it. The expansion power supply extends the backplane bus power for up to 17 I/O
modules to the right of the supply and creates a new field voltage partition segment for
driving field devices. The expansion power supply separates field power from I/O modules
to the left of the unit, effectively providing functional and logical partitioning for the
following.
• Separate field power between input and output modules.
• Separate field power to the analog and digital modules.
• Group modules to perform a specific task or function.
The dark-gray color of the expansion power supply allows for easy visual inspection and
identification. Refer to the figure to identify external power supply components.
Use multiple expansion power supplies with POINT I/O adapters to assemble a full
system. With any POINT I/O adapter, use an expansion power supply to add additional
modules in 4…17 module increments, for a total of 63 I/O modules.

The locking mechanism locks the module to the DIN rail.
Remove the Power Supply
To remove an expansion power supply, proceed as follows.
1. Pull up on the RTB removal handle to remove the terminal block.
2. Remove the module to the right of the 1734-EP24DC module from its base unit.
3. Use a small-bladed screwdriver to rotate the DIN rail locking screw to a vertical
position.
This releases the locking mechanism.
4. Lift straight up to remove.
Replace the Power Supply
To install a replacement expansion power supply, proceed as follows.
1. Remove the module to the right of the power supply from its base unit.
2. Position the power supply vertically above the DIN rail.

3. Slide the power supply down allowing the interlocking side pieces to engage the
adjacent modules (both left and right sides).
4. Press firmly to seat the power supply on the DIN rail.
The power supply locking mechanism snaps into place.
5. Reinsert the module into the base next to the expansion power supply.
Wire the Power Supply
WARNING: 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.
ATTENTION: Use the 1734-EP24DC expansion power supply only with
adapter class products.
ATTENTION: Use the 1734-EP24DC expansion power supply only with 1734
POINT I/O adapters, such as the 1734-ADN DeviceNet adapter.
