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.

Preface
What Is Intrinsically Safe?
What are Product Certifications?
According to Article 504 of the National Electrical Code, NFPA 70, an
intrinsically safe (I/S) product is defined as one in which no spark or thermal
effect generated during normal functioning and/or during specific fault
conditions is able to ignite a given explosive atmosphere.
One example of an I/S product is FLEX Ex distributed I/O control.
A product certification is a guarantee that the product has been designed and
manufactured with the required I/S specifications and protection. Considering
the potential danger in hazardous locations, product certification is required
for all I/S products.
Three Types of Product Certifications
In this reference manual, we describe three types of product certifications and
how they relate to FLEX Ex products:
• CENELEC - European Electrotechnical Committee for
Standardization. This is the standard in all European Union
countries.
• UL and C-UL - Underwriters Laboratories (UL in the United States
and C-UL in Canada)
• FM - Factory Mutual, another available certifying body in the United
States
What are Entity Parameters?
FLEX Ex products are certified to the appropriate CENELEC, UL, C-UL and
FM standards, depending on the module.
Entity parameters provide a system of quantifying and matching safe levels for
voltage, current, inductance, and capacitance when connecting field devices
and system devices together.
FLEX Ex uses entity parameters to quantify safe levels when connecting I/O
modules to field devices. Inputs and outputs are specified with:
• open-circuit voltage (U
• short-circuit current (I
• allowed capacitance (C
• allowed inductance (L
Switched outputs are specified as if they were inputs.
Field devices using entity parameters are specified with:
• maximum input voltage (U
or Voc)
o
or Isc)
o
or Ca)

The following is a short explanation of how entity-based architectures help
simplify IS system design.

appropriate match.

The following sections describe key terms used in this reference manual:
Hazardous Area Designation
A hazardous area is designated as any location in which a combustible material
is or may be present in the atmosphere in sufficient concentration to produce
an ignitable mixture.
The North American method identifies these areas by Class, Division, and
Group while the IEC (CENELEC) designates these areas by Zone and Gas
Group.
Recently, North America has adopted the Zone method of identifying
hazardous locations as an option to the Division method.
Class Designation
Class identifies the type of hazardous atmosphere.
Class I Gas or vapor
Class II Dust
Class III Fiber or flying (no group designation)

Use in North American Hazardous Locations
FLEX Ex modules are rated for installation in Class I Division 1 & 2, Groups
A-D hazardous areas. They are also rated to connect to field devices that are
located in Class I, II, or III, Groups A-G hazardous areas.
If FLEX Ex components are to be installed in a Class II or III location in your
application, you can mount them in a suitable, dust-proof enclosure with the
appropriate connectors, glans, and seals. For example, a NEMA 9 enclosure
may be appropriate. The FLEX Ex modules are rated to connect to devices in
Class II or III locations.
FLEX Ex modules are rated for installation in North American Class I Zone 1
& 2, Groups IIC, IIB, & IIA hazardous areas. They are also rated to connect
to field devices that are located in North American Class I Zone 0, 1, & 2,
Groups IIC, IIB, & IIA hazardous areas.
As always, observe local code requirements when applying your FLEX Ex
application.
Use in CENELEC Hazardous Locations
FLEX Ex modules are rated for installation in European Zones 1, 2, and 22.
They are also rated to connect to field devices that are located in European
Zones 0, 1, 2, 21, and 22 hazardous areas. The FLEX Ex power supplies
(1797-PS1E and -PS2E2) are rated for use in Zones 1 and 22.
If FLEX Ex components are to be installed in a European Zone method dust
or fiber location in your application, you must mount them in an approved,
dust-proof enclosure with the appropriate connectors, glans, and seals.
Pepperl+Fuchs have three cabinets that are approved for use with FLEX Ex
components in Zone 22 applications: IVK2-ISRPI-V8LC;
IVK2-ISRPI-V8HYW; and IVK2-ISRPI-V16LC. P+F has offices in
Twinsburg, Ohio, USA, and Mannheim, Germany. See their website at
www.pepperl-fuchs.com.
As always, observe local code requirements when applying your FLEX Ex
application.

General Installation
Label here or under here
FLEX Ex I/O modules must be used with a 1797-TB3 or -TB3S intrinsically
safe terminal base unit.
You will need to rotate the keyswitch (1) to the correct position depending on
the module. Refer to the module’s installation instructions for more
information. Do not change the position of the keyswitch after wiring the
terminal base unit.
Make certain that you only connect terminal base units to other intrinsically
safe system modules, adapters or power supplies to maintain the integrity of
the intrinsically-safe backplane.
Remove cap plug and attach another intrinsically safe terminal base unit to the
right of the terminal base unit (2) if required.

Installation in Zone 1
Installation in Zone 22
Electrostatic Charge
European Community Directive Compliance
Modules, adapters, and terminal base units must not be exposed to the
environment. Provide a suitable enclosure. The modules, adapters, and
terminal base units have a protection factor of IP20.
ATTENTION
When the ControlNet Ex system is installed in Zone 22, all system
components (except the coax cable and ControlNet Ex taps) must be installed
in cabinets of the following type: IVK-ISRPI-V16LC; IVK-ISRPI-V8HYW;
or IVK-ISRPI-V8LC. For more information on these cabinets, see page 1-4.
Protect the system against electrostatic charge. Post a sign near each module:
Attention! Avoid electrostatic charge. For your convenience, a sign which
can be cut out and posted is included in this chapter.
If this product has the CE mark it is approved for installation within the
European Community or EEA regions. It has been designed and tested to
meet the following directives.
Modules, adapters, and terminal base units cannot be used
in an intrinsically safe environment after they have been
exposed to non-intrinsically safe signals.
EMC Directive
All system components are tested to meet the Council Directive 89/336/EEC
Electromagnetic Compatibility (EMC), as amended by 92/31/EC and
93/68/EEC, by applying the following standards as appropriate:
• EN61000-6-4:2001, Electromagnetic Compatibility (EMC) - Part 6-4:
Generic Standards - Emission Standard for Industrial Environments
(Class A)
• EN61000-6-2:2001, Electromagnetic Compatibility (EMC) - Part 6-2:
Generic Standards - Immunity for Industrial Environments
• EN61326:1997 + A1-A2, Electrical Equipment for Measurement,
Control, and Laboratory Use - Industrial EMC Requirements
LVD Directive
All power supplies are tested to meet the Council Directive 73/23/EEC Low
Voltage Directive, as amended by 93/68/EEC (LVD), by applying the
following standards as appropriate:
• EN50178:1997, Electronic Equipment for Use in Power Installations
