General requirements for installation
– The documentation for hazardous area classification (zone classification) according to
EN/IEC 60079-10 must be available.
– The equipment must be verified as suitable for use in the classified area.
– After installation an initial test run of the complete equipment and the plant according
to EN/IEC 60079-17 must be performed before regular operation is started.
Requirements regarding cabling
– Cables must fulfill the requirements set forth in EN/IEC 60079-14.
– 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.
– Observe the clamping range of the cable glands for cable selection.
– 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 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 IEC 60614-2-5 are not suitable.
– Conduits must be protected against vibration.
– Use a suitable thread sealant, as detailed in EN/IEC 60079-14.
– Protect stranded wires against fraying with ferrules.
– Keep clearance and creepage distances for the connected wires in accordance with
EN/IEC 60079-7 in case of non-intrinsically safe wiring, respectively in accordance with
IEC 60079-11 in case of intrinsically safe wiring.
– 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/IEC 60079-14
– The meter body and the electronic housing must be connected to the potential
equalization.
– Where the FLOWSIC30 is installed in a grounded metal duct, no additional grounding is
required for the meter body. The electronics housing must nevertheless be separately
grounded.
