Installation Instructions

ArmorPoint I/O Field Potential Distributor,
Series A

(Cat. No. 1738-FPD)

The field potential distributor (Cat. no. 1738-FPD) lets you change the
field power distribution source for I/O modules to the right of the
1738-FPD. This facilitates logical or functional partitioning of high
I/O-mix applications.

The 1738-FPD field potential distributor passes through all
ArmorPoint™ I/O backplane signals except the internal power bus.

You can use the 1738-FPD with a range of voltage inputs, including
5V dc to 250V dc and/or 24V ac to 240V ac applications and I/O
modules. The mounting base ships with the module.

SHOCK HAZARD

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.ab.com/manuals/gi) describes some important differences betwee n 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 liabl e for indirect or consequential damages
resulting from the use or application of th is equipment.

The examples and diagrams in this manual are included solely for illustrati ve purposes. Because of the
many variables and requirements associated with any particular installation, Rockwell Automation, Inc.
cannot assume responsibility or liability for actual use based on the examples and diagrams.

No patent liability is assumed by Rockwell Automation, Inc. with respect to use of information, circuits,

ATTENTION

Environment and Enclosure

This equipment is intended for use in overvoltage
Category II applications (as defined in IEC
publication 60664-1), at altitudes up to 2000 meters
without derating.

This equipment is considered Grou p 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 "enclosed" equipment.
It should not require additional system enclosure
when used in locations consistent with the enclosure
type ratings stated in the Specifications section of this
publication. Subsequent sections of this publication
may contain additional information regarding
specific enclosure type ratings, beyond what this
product provides, that are required to comply with
certain product safety certifications.

NOTE: See NEMA Standards publication 250 and
IEC publication 60529, as applicable, for
explanations of the degrees of protection provided
by different types of enclosure. Also, se e the
appropriate sections in this publication, as well as
the Allen-Bradley publication 1770-4.1 ("Industrial
Automation Wiring and Grounding Guidelines"), for
additional installation requirements pertaining to this
equipment.
