The valve control modules limit current and voltage in the event of a fault, which

allows the solenoid valves to be operated "intrinsically safe" and thus guarantee

separation between Ex and non-Ex areas.

6.4.3.4 Execution and verification of the connection of internal and external circuits

For internal and external connections, the intrinsically safe circuits are defined by

the sensor module and its designation.
The distance within an intrinsically safe circuit and to earthed parts is at least 3

mm.
The distance between different intrinsically safe circuits is at least 6 mm.
The length of the stripping must not exceed 5 mm.

Execution of the connection of external circuits

The standards for the electrical installation of intrinsically safe circuits

according to EN 60079-11 must be observed.
► Check distance between non-insulated strands of at least 3.0 to earthed

parts.

► Check distance between intrinsically safe circuits of at least 6.0 mm.

► Check the length of the stripping of max. 9 mm.

► Check the cables for tight fit.
