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
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 more installation requirements.
• NEMA Standard 250 and EN/IEC 60529, as applicable, for explanations of
the degrees of protection provided by enclosures.
ATTENTION: This equipment is sensitive to electrostatic discharge that 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.

Before You Begin
The purpose of the module is to break the field power distribution.
Use the module to change the field power distribution source for I/O modules to the right
of the module. This facilitates logical or functional partitioning of low-channel count,
high I/O-mix applications using the 1734-adapters, 1734-PDN, and 1734D Series
communication interfaces. This module passes through all POINT I/O™ backplane
signals except the internal field power bus for field devices.
You can use the module with a range of voltage inputs to include the following:
• 5…250V DC applications
• 24…240V AC applications
•I/Omodules

Install the Module
To install the module on the DIN rail (Allen-Bradley® part number 199-DR1; 46277-3;
EN50022), proceed as follows.
1. Position the module vertically above the DIN rail.
2. Engage the interlocking pieces with the unit on the left.
3. Press down firmly to install the module on the DIN rail.
The locking mechanism locks the module to the DIN rail.
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,
Rockwell Automation publication 1770-4.1, for more information.
WARNING: When used in a Class I, Division 2, hazardous location, this
equipment must be mounted in a suitable enclosure with proper wiring method
that complies with the governing electrical codes.
ATTENTION: If 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.

Remove the Module
To remove a 1734-FPD or 1734-FPDK module, you must first remove any I/O module
installed in the base to the right. To remove the 1734-FPD or 1734-FPDK module from
the DIN rail, proceed as follows:
1. Pull up on the RTB removal handle to remove the terminal block.
2. Use a small-bladed screwdriver to rotate the DIN rail locking screw to a vertical
position. This releases the locking mechanism.
3. Lift straight up to remove.
Replace the Module
To install a replacement module in an existing system, proceed as follows:
1. Position the module vertically above the DIN rail.
2. Slide the module down to engage the interlocking sides pieces to the adjacent
modules on both the left and right sides.
3. Press down firmly to install the module on the DIN rail. The module locking
mechanism snaps into place.
WARNING: When you connect or disconnect the removable terminal
block (RTB) with field-side power applied, an electrical arc can occur. This can
cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding
