Notes
Preface
What Is Intrinsically Safe?
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 ExTM distributed I/O control.
What are Product
Certifications?
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.
Two Types of Product Certifications
In this reference manual, we describe two 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 cUL - Underwriters Laboratories (UL in the United
States and cUL in Canada)
All FLEX Ex products are certified to CENELEC, UL and cUL standards.
What are Entity
Parameters?
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 (Uo or Voc)
• short-circuit current (Io or Isc)
• allowed capacitance (Co or Ca)
• allowed inductance (Lo or La)
Switched outputs are specified as if they were inputs.

Preface
Field devices using entity parameters are specified with:
• maximum input voltage (Ui or Vmax)
• maximum input current (Ii or Imax)
• maximum internal capacitance (Ci)
• maximum internal inductance (Li)
In use, the sum of all the input Ci and Li in a control loop cannot
exceed the Co and Lo. Also, the sum of all the Uo and Io cannot
exceed the input Ui and Ii.
The following is a short explanation of how entity-based architectures
help simplify IS system design.
Entity Parameters Example
An output channel and the valve it will drive are illustrated in the
following figure. By comparing entity parameters, you can quickly
determine the 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.

FLEX Ex usage in Class II and III (Dusts and Fibers) Hazardous Locations
(North America)
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 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 4 enclosure may be appropriate.
As always, observe local code requirements when applying your FLEX
Ex application.
FLEX Ex usage in Zone Method Dusts and Fibers Hazardous Locations
FLEX Ex modules are rated for installation in North American Class I
Zone 1 & 2, Groups IIC, IIB & IIA and European 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 and European Zone 0, 1, & 2, Groups IIC, IIB, &
IIA hazardous areas.
If FLEX Ex components are installed in a North American or European
Zone method dust or fiber location in your application, you can
mount them in a suitable enclosure with the appropriate connectors,
glans, and seals. For example, a North American NEMA 4 or better
enclosure may be appropriate.
As always, observe local code requirements when applying your FLEX
Ex application.
For Zone application, especially in Europe, normal practice calls for
the end application to obtain the dust and fiber rating due to strong
dependence on wiring and other non-equipment related
requirements. For example, FLEX Ex’s North American Class I Zone 0,
1, & 2 Groups IIC, IIB & IIA and European Zone 0, 1, & 2, Groups IIC,
IIB & IIA hazardous area rating is used as the basis for the overall
application to gains its dust and fiber certification.

and 2; Class II, Division 1 and 2; Class III, Division 1 and 2) to connect
two 1797-RPFM modules or they can be installed through different
locations into the non-hazardous location to connect the 1797-RPFM
with any approved associated apparatus.
All cables and fiber media that are not light blue must be marked as IS
using the 1797-EXMK marking kit or other locally approved IS
identification and/or segregation method.

ú The wiring contained within the nonintrinsically safe wiring
compartment and the intrinsically safe wiring compartment shall be
separated from each other. Care must be taken to guarantee the
separation of nonintrinsically safe and intrinsically safe wiring. The
partitions within the power supply provide the necessary isolation for
the electronics and the wiring, however, extreme care must be taken
to guarantee wires are contained within their appropriate
compartment and cannot contact any of the electronics.
÷ WARNING: Substitution of components may impair intrinsic safety.
AVERTISSEMENT: La substitution de composant peut compromettre la
