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
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-IN041
• NEMA Standards publication 250 and IEC publication 60529, as applicable,
for explanations of the degrees of protection provided by different types of
enclosure.

About the Module
The purpose of the POINT I/O™ Field Potential Distributormodule 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

POINT I/O Field Potential Distributor Modules 7
Install the Module
To install the module on the DIN rail, 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 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: 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.

Remove the Module
To remove a 1734-FPD module, you must first remove any I/O module installed in the
base to the right. To remove the 1734-FPD 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:
WARNING: When you connect or disconnect the Removable Terminal Block
(RTB) with field side power applied, 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.
1. Position the module vertically above the DIN rail.
2. Slide the module down to eng age 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.
