ATTENTION

20128-M

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.

1. Rotate keyswitch (1) on terminal base unit (2) clockwise to position 6 as required for this type of module.

Do not change the position of the keyswitch after wiring the terminal base unit.

2. Make certain the flexbus connector (3) is pushed all the way to the left

to connect with the neighboring terminal base/adapter. You cannot install the module unless the connector is fully extended.

3. Make sure the pins on the bottom of the module are straight so they will align properly with the connector in the terminal base unit.

4. Position the module (4) with its alignment bar (5) aligned with the groove (6) on the terminal base.

5. Press firmly and evenly to seat the module in the terminal base unit. The module is seated when the latching mechanism (7) is locked into

the module.

6. Make certain that you only connect terminal base units to other intrinsically safe system modules or adapters to maintain the integrity of the intrinsically-safe backplane.

ATTENTION

7. Remove cap plug (8) and attach another intrinsically safe terminal base unit to the right of this terminal base unit if required.

Installation in Zone 1

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

This module cannot be used in an intrinsically safe environment after it has been exposed to non-intrinsically safe signals.

Installation in Zone 22

When the module 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 Pepperl+Fuchs GmbH, Lilienthalstrasse 200, 68307 Mannheim, Germany. Information available at 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:

Pepperl+Fuchs GmbH 68307 Mannheim IVK2-ISRPI-V8LC (or IVK2-ISRPI-V8HYW or IVK2-ISRPI-V16LC) II 3 D Ex tD A22 IP54 T70 °C X CE Serial (manufacturing) number Model

Removal and Insertion Under Power

These modules are designed so you can remove and insert them under power. However, take special care when removing or inserting modules in an

active process. I/O attached to any module being removed or inserted can change states due to its input/output signal changing conditions. If you insert or remove the module while backplane power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations. Be sure that power is removed or the area is nonhazardous before proceeding.

European Communities (EC) Directive Compliance

Set the Fault Detect Switch

A switch, located on the backside of the module, lets you select the action of the module when a fault (wire off or short circuit) is detected. Switch position 1 determines the action for channels 0 to 3, position 2 for channels 4 to 7, position 3 for channels 8 to 11, and position 4 for channels 12 to 15.

Set the switch:

• OFF to disable fault detection for the selected channels.

• ON to enable fault detection for the selected channels.

 Simple apparatus is defined as a device which neither generates nor

stores more than 1.2V, 0.1 A, 20 μJ, or 25 mW.

 Wiring methods must be in accordance with the National Electric Code,

ANSI/NFPA 70, Article 504 and 505. For additional information refer to ANSI/ISA RP12.6.

 This module, 1797-IBN16, must be used with terminal base 1797-TB3

 Terminals 36 to 39, and 46 to 49 shall not be connected.

Substitution of components may impair intrinsic safety.

La substitution de composant peut compromettre la securite intrinseque.
