(e.g. IEC 60079-14).
– Pay attention to the maximum process conditions according to the manufacturer's Operating Instructions.
At high medium temperatures: note flange pressure load capacity as a factor of temperature.
– Connect the device using suitable cable and wire entries* or using piping systems of protection type
"Pressure-tight Enclosure (Ex d)".
* For selection criteria refer to EN 60079, Chapter 10.3.
– To maintain the ingress protection IP66/67 of the housing, install the housing cover and cable glands correctly.
Close unused entry glands with approved (Ex d) sealing plugs.
– Install the device to exclude any mechanical damage or friction during the application. Pay particular attention to flow
conditions and tank fittings.
– Support extension tube of Soliphant M FTM51 if a dynamic load is expected.
– Install the device to exclude impact and friction sparks on the aluminium housing.
– Only install the devices in media for which the wetted materials have sufficient durability;
e.g. process connection seal (see Technical Information TI 392F).
– Use a process connection seal that meets the materials compatibility and temperature requirements.
– When connecting the cables, ensure there is adequate strain relief at place of installation.
