Installation Instructions
ControlNet Ex Redundant Media Adapter
(Cat. No. 1797-ACNR15)
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 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 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, equipment, or software described in this manual.
Reproduction of the contents of this manual, in whole or in part, without written permission
of Rockwell Automation, Inc. is prohibited.
Throughout this manual we use notes to make you aware of safety considerations.

Publication 1797-5.14 - March 2004
Use the redundant media adapter module to connect FLEX ExTM modules to
the ControlNetTM Ex network.
ATTENTION Environment and Enclosure
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 supplies 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 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.

Module Installation
This adapter must not be exposed to the environment. Provide a suitable
metal enclosure. This adapter has a protection factor of IP20.
Make certain that you only connect ControlNet Ex adapters to other
intrinsically safe system modules to maintain the integrity of the
intrinsically-safe backplane.
1. Position the ControlNet Ex adapter module (A) on a 35 x 7.5mm
DIN rail (B) (A-B pt. no. 199-DR1) at a slight angle.
2. Hook the lip on the rear of the adapter (A) onto the top of the DIN
rail (B), and rotate the module onto the rail.
3. Press the adapter module down onto the DIN rail until flush.
4. The locking tab (C) should snap into position and lock the adapter
module to the DIN rail.
ATTENTION This product is grounded through the DIN rail to the dedicated
intrinsic safety ground. Use zinc plated yellow-chromate steel
DIN rail to assure proper grounding. The use of other DIN rail
materials (e.g. aluminum, plastic, etc.) that can corrode, oxidize,
or are poor conductors, can result in improper or intermittent
grounding.

5. If the adapter does not snap into position, use a screwdriver or similar
device to move the locking tab down while pressing the adapter
module flush onto the DIN rail. Release the locking tab to lock the
module in place.
6. If necessary, push up on the locking tab to lock.
7. Connect the adapter wiring as shown under “Wiring” later in this
document.
Mounting (or Replacing) the Adapter on an Existing System
1. Disconnect the BNC connectors from the front of the ControlNet Ex
adapter.
2. Remove the front power plug from the ControlNet Ex adapter.
3. Remove the I/O module from the terminal base unit that is to the
immediate right of the ControlNet Ex adapter.
4. Push the flexbus connector toward the right side of the terminal base
to unplug the backplane connection.
5. Release the locking tab and remove the adapter.
6. Remove the backplane connector cover from the adapter.
ATTENTION Make certain that the flexbus connector is completely clear of
the adapter. The slide must be completely to the right and the
raised spot on the slide visible.

7. Before installing the new adapter, notice the notch on the right rear of
the adapter.
This notch accepts the hook on the terminal base unit. The notch is
open at the bottom. The hook and adjacent connection point keep the
terminal base and adapter tight together, reducing the possibility of a
break in communication over the backplane.
8. Complete the adapter mounting as shown below.
9. If the adapter module does not lock in place, use a screwdriver or
similar device to move the locking tab (C) down while pressing the
adapter module flush onto the DIN rail. Then release the locking tab
to lock the adapter module in place.
10. If necessary, push up on the locking tab to lock.
11. Reinstall the I/O module into the terminal base unit.
12. Make sure the last terminal base has its right-side flexbus connector
cover in place.
ATTENTION Make certain that the hook on the terminal base is properly
hooked into the adapter. Failure to lock the hook into the
adjacent base/adapter can result in loss of communication on
the backplane.

Push down and in at the
same time to lock the
adapter to the DIN rail.
When the adapter is locked onto the DIN
rail, gently push the flexbus connector into
the adapter to complete the backplane.
