About the Module
Use the 1786-RPFS module when you need a short-distance fiber link between
two ControlNet products. Maximum distance is 300 m (984 ft). The fiber link
provides ground isolation between nodes and is less susceptible to noisy
environments than copper media.
IMPORTANT
The supported distance depends on the quality of the fiber,
number of splices, and connectors. The total light loss through
the fiber link must be less than 4.2 dB.

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 m (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 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, 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, Rockwell
Automation 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 different types of enclosure.
ATTENTION: This equipment is not resistant to sunlight or other
sources of UV radiation.

Mount the Module
Mount the module on a 35 x 7.5 mm (1.38 x 0.30 in.) DIN rail, Allen-Bradley
part number 199-DR1, 46277, EN 50022.
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.
TIP
Horizontal mounting is preferred. Vertical mounting is allowed.
We recommend that the 1786-RPA/B repeater adapter module be
mounted at the top if vertical mounting is chosen.

30077
IMPORTANT
Make certain that you secure the adapter and repeater modules
with DIN-rail anchors. If you do not, loss of communication or
module damage may result.
Consult with your local distributor for attenuation specifications
before you purchase your fiber media components.
You can attach a maximum of four modules to the repeater adapter, or, the
number of modules whose total power consumption does not exceed
1.6 A @ 5V DC, whichever occurs first.
IMPORTANT
If you exceed the module or power limit, you may damage the
repeater adapter and modules.

10 ControlNet Modular Repeater Short-distance Fiber Module
Connect the Fiber Module
This module requires a pre-terminated zipcord wiring kit. The kits are offered in
a variety of lengths. Consult with your local distributor for attenuation
specifications before you purchase your fiber media components.
The zipcord uses a duplex cable that contains two separate fibers, one for
transmit and one for receive. If you are wiring only one channel, you can use
either channel 1 or channel 2.
1. Hold down the latch and insert the channel 1 zipcord connector into the
A and B connectors until the pins and latch lock into place.
Make certain you insert the blue pin, receive, of the zipcord connector
in A and the black pin, transmit, into B.
Channel 1, A and B
Channel 2, A and B
30079
2. Hold down the latch and insert the other end of the duplex cable into
another module by using either channel 1 or channel 2 of the
other module.
IMPORTANT
The duplex cable is manufactured with the fiber reversed on
opposite ends. This automatically connects channel A of one unit
to channel B of the other. Do not connect more than one duplex
fiber or two simplex fibers between the same modular repeaters,
even if they are from different modules on the same repeater.
