5 INTRINSICALLY SAFE APPLICATIONS
5.1
GENERAL INFORMATION AND SAFETY INSTRUCTIONS
For the combined connection of the different supply, input and output circuits, the
instructions in this manual must be observed. From the safety point of view the circuits
shall be considered to be connected to earth
Certificates, safety values, control drawing and declaration of compliance can be found in
the document named:
“Fluidwell F1..-..-XI - Documentation for Intrinsic safety”
For installation under ATEX directive: this Intrinsically safe device must be installed in
accordance with the latest ATEX directive and product certificate KEMA 03ATEX1074 X.
For installation under IECEx scheme: this Intrinsically safe device must be installed in
accordance the product certificate IECEx DEK 11.0042X.
Exchange of Intrinsically safe battery FWLiBAT-0xx with certificate number
KEMA 03ATEX1071 U or IECEx KEM 08.0005U is allowed in Hazardous Area.
Read chapter 6 for battery replacement instructions.
When the enclosure of the F116-P is made of aluminum alloy, when used in a potentially
explosive atmosphere requiring apparatus of EPL Ga, the indicator shall be installed so,
that even in the event of rare incidents, an ignition source due to impact or friction sparks
between the enclosure and iron/steel is excluded.
When two or more active Intrinsically safe circuits are connected to the indicator, in order
to prevent voltage and/or current addition, applicable to the external circuits, precautions
must be taken to separate the Intrinsically safe circuits in accordance with EN 60079-11.
To maintain the degree of protection of at least IP65 in accordance with IEC 60529,
suitable cable entries and blanking elements must be used and correctly installed.
For enclosures and windows with a high surface resistance, potential charging hazard
exists. Do not rub these surfaces of the indicator. Clean window and enclosure only with
a lint-free cleaning cloth made damp with a mild soap solution.
Chapter 4 shows general information regarding the electrical installation of your indicator.
This chapter gives additional specific information regarding Intrinsically safe installation
and overrules the information given in chapter 4.
Mounting, electrical installation, start-up and maintenance of this device may only be
carried out by trained persons authorized by the operator of the facility. Persons must
read and understand this manual before carrying out its instructions.
This device may only be operated by persons who are authorized and trained by the
operator of the facility. All instructions in this manual are to be observed.
Make sure, the measuring system is correctly wired up according to the wiring diagrams.
Protection against accidental contact is no longer assured when the housing cover is
removed or the panel cabinet has been opened (danger from electrical shock). The
housing may only be opened by trained persons authorized by the operator of the facility.
Take careful notice of the "Safety rules, instructions and precautionary measures" in the
front of this manual.
Special conditions for safe use mentioned in both the certificate and the installation
instructions must be observed for the connection of power to both input and / or output
circuits.
When installing this device in hazardous areas, the wiring and installation must comply
with the appropriate installation standards for your industry.
Study the following pages with wiring diagrams per classification.
