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.

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.
