installation regulations.
Avoid electrostatic charging on plastic units and cables.
To avoid electrostatic charging clean the unit with a damp cloth only. Rubbing with non-
conductive materials must be strictly avoided.
To avoid electrostatic charging steps must be taken to ensure the equalisation of potential
of metal parts (plug housing, fixing elements, protective housing, etc.).
Do not mount the unit in the dust flow.
Avoid dust deposits on the units.
Protect the units and the cables efficiently against damage.
For the connections and the electrical technical data please see the unit marking or the
technical data sheet.

Special conditions for safe operation
The housing and housing parts made of plastic were tested in accordance with table 8 of
EN 60079-0 for group II and table 5 of EN 61241-0 for group II and for a low mechanical
risk with an impact energy of 4 joules.
Use sockets which are suited for hazardous areas, e.g. ifm sockets EVC**A with Ex
certificate (certificate number BVS 08 ATEX E 109 U).
Protect the sockets by tightening the hexagon coupling nut sufficiently according to the
requirements of the Ex protection related operating instructions 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 if you can ensure a durable marking.
Maintenance / Repair
The unit must not be modified nor can it be repaired. In case of a fault please contact the
manufacturer.
If required, the technical data sheets and EC declarations of conformity can be obtained
from the manufacturer (see cover sheet). Indicate the article number.
