Installation
Subject to change without notice
General requirements for installation
– The documentation for hazardous area classification (zone classification) according to
EN/IEC60079-10 must be available.
– The equipment must be verified as suitable for use in the classified area.
– Additional requirements must be observed for use of transducers in Zone 0 as
described above.
– After installation an initial test run of the complete equipment and the plant according
to EN/IEC60079-17 must be performed before regular operation is started.
Requirements regarding cabling
– Cables must fulfill the requirements set forth in EN/IEC60079-14.
– Cables that are subject to exceptional thermal, mechanical or chemical stress must be
specially protected, e.g. by laying them in protective tubing.
– Cables that are not installed fire proof must be flame retardant according to IEC
60332-1.
– Cables for Ex e must comply with EN/IEC 60079-14 section 11.
– Observe the clamping range of the cable glands for cable selection.
– Use Ex e II respectively Ex i II certified cable glands with adequate ingress protection
rating as alternate replacement only.
– For intrinsically safe wiring and an ambient temperature range between
-20°C to +60°C, the existing metal cable glands may be replaced with light-blue plastic
cable glands (available on request).
– Replace the existing cable glands with suitable cable glands if installation with armored
cables is intended.
– When delivered, the cable glands are secured by default with a sealing plug. If the cable
glands are not used, only sealing plugs with EX e II approval must be used.
– Conduit systems must comply with EN/IEC 60079-14, section 9.4 and 10.5. In
addition, compliance with national and other relevant regulations is required
– "Conduits" according to IEC 60614-2-1 and IEC60614-2-5 are not suitable.
– Conduits must be protected against vibration.
– Use a suitable thread sealant, as detailed in EN/IEC60079-14, section 9.4.
– Protect stranded wires against fraying with ferrules.
– Keep clearance and creepage distances for the connected wires in accordance with
EN/IEC60079 and EN/IEC 60079-11 respectively.
– Connect unused wires to ground or safeguard so that a short circuit with other
conductive parts is excluded.
– Carry out potential equalization in accordance with EN/IEC6079-14
– The meter body and the electronic housing must be connected to the potential
equalization.
– Where the FLOWSIC600 is installed in a grounded metal duct, no additional grounding
is required for the meter body. The electronics housing must nevertheless be separately
grounded.
