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
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

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 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 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.

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 (such as aluminum or plastic) that can corrode, oxidize,
or are poor conductors, can result in improper or intermittent
grounding.

Make certain that you only connect ControlNet Ex adapters to other
intrinsically safe system modules to maintain the integrity of the
intrinsically-safe backplane.

Install the Adapter

1. Position the ControlNet Ex adapter module (A) on a 35 x 7.5 mm
DIN rail (B) (A-B pt. no. 199-DR1) at a slight angle.

ATTENTION

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.

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.

Mount (or Replace) 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.

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.

5. Release the locking tab and remove the adapter.

6. Remove the backplane connector cover from the adapter.

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.

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.

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.

8. Complete the adapter mounting as shown below.

10. Push up on the locking tab to lock, if necessary.

11. Reinstall the I/O module into the terminal base unit.

12. Make sure the last terminal base has its right-side flexbus connector

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.

WARNING

Installation in Zone 1

The adapter must not be exposed to the environment. Provide a suitable
metal enclosure. The adapter has a protection factor of IP20.

The adapter cannot be used in an intrinsically safe environment
after they have been exposed to nonintrinsically safe signals.

Installation in Zone 22

When the adapter is installed in Zone 22, the following cabinets must be used:
IVK-ISRPI-V16LC; IVK-ISRPI-V8HYW; or IVK-ISRPI-V8LC. These
cabinets can be purchased from:

Telephone [phone]
www.pepperl-fuchs.com

The IS-RPI cabinets (type IVK2-ISRPI-V8LC, IVK2-ISRPI-V8HYW, or
IVK2-ISPRI-V16LC) ensures the basic protection for the intrinsically safe
apparatus of the Flex Ex system for use in Zone 22. It corresponds with
category 3D according to RL 94/9 EG and with the type label marked with
the following information:
