3 Installation

Wiring and electrical characteristics: → Technical data and → Device marking

▶ Protect device and cable against destruction.
▶ Avoid electrostatic charging on plastic housings and cables.
▶ Rubbing the device with non-conductive materials must be strictly avoided.
▶ To avoid electrostatic charging, ensure the equalisation of potential of metal parts (connector housing, fixing elements, protective housing, etc.).
▶ Do not mount the device in the dust flow.
▶ Avoid dust deposits on the device.
▶ Only open or close M12 fittings in a sufficiently clean environment.
▶ Avoid soiling of the connector area.
▶ Avoid direct exposure to high levels of UV light (sunlight). Mount the device in a protected place.

3.1 Special conditions for safe operation

The housing and housing parts made of plastic have been tested in accordance with IEC 60079-0 for group II and for a low mechanical risk with an impact energy of 4 joules.

▶ Use ifm sockets EVC**A with Ex certificate (certificate number BVS 08 ATEX E 109 U).
▶ Secure the sockets by tightening the coupling nut sufficiently according to the requirements of the socket.
▶ Do not separate the connector when energized.
▶ Apply a durable warning in suitable form close to the connector reading: "Do not separate when energized" or use the enclosed label to ensure a durable marking.
▶ Only operate the device in an environment which ensures pollution degree 2 or higher according to IEC 60664-1.

4 Maintenance, repair and disposal

▶ Clean the device with a damp cloth only.

No modifications or repairs may be made to the device.

▶ In case of a fault please contact the manufacturer.

▶ If required, request data sheets or type examination certificates / certificates from the manufacturer ( → cover sheet / back).
