Special conditions for safe operation
• Avoid electrostatic charging on plastic units and cables.
• Do not mount the module in the dust flow.
• Avoid dust deposits on the splitter box.
• Avoid electrostatic charging, only clean the unit with a damp cloth. In principle,
rubbing with non-conductive materials must be avoided.
• Avoid direct radiation with high UV components (sunlight), mount the unit in a
protected place.
• The unit is rated for low impact energy (EN60079-0, table 8, 4 joules). Protect
splitter box and cable against destruction.
• The unit with the M12 protective cover in place meets the requirements of the
categories 3D and 3G.
• Use connectors which are suited for hazardous areas, e.g. ifm connectors
EVC**A with Ex certificate (certificate number BVS 08 ATEX E 109 U).
• Do not separate the module upper part from the FC lower part while live.
• Do not separate the M12 connectors when energised.
• When connecting an M12 connector ensure that the O-ring is present and
undamaged in the socket.
• Check the tightening torque of the screws two weeks after mounting and
retighten them, if necessary.
• Protective caps, housing upper and lower parts and M12 fittings may only be
opened or closed in a sufficiently clean environment.
• For use in hazardous areas according to the indication compliance with the
protection rating is essential. Therefore appropriate care must be taken when
mounting the housing and the seals.
• Only use the supplied lower part and supplied seals.
• If only one cable duct is used, the other one has to be closed using the flat
cable blank.
• Flat cables must be firmly laid. Loads on the entry caused by strain or
movement of the flat cables must be avoided.
