The maximum external inductance L (sensor coil) can be calculated with the following term: L = 2 x E x ( Ri + Ro / 1,5 x Uo)2 Whereby E= 40µJ for group IIC and E = 160µJ for group IIB will be inserted and Ro is the total resistance (coil resistance + series resistance).

Special conditions for safe use / Installation instructions for 9739MVD**I*****.
5.1
For the application of the transmitter in an ambient temperature of less than - 20 °C suitable cable and cable entries or conduit entries certified for this condition shall be used.
5.2
If certified conduit entries are used for the connection of the transmitter enclosure, the associated stopping boxes shall be installed immediately at the enclosure.
5.3
The transmitter shall only be installed within the intended hazardous area if metal cable entries (with ¾”–14 NPT threading) are used which are classified as Ex d IIC and are for enclosures with >2dm3 and are certified by an authorized test station.
5.4
Entry holes which are not being used must be sealed with blanking plugs and which are classified as Ex d IIC and are certified by an authorized test station.
5.5
For installation outside the hazardous area, it is allowed to use cable entry fittings that are not flameproof.
5.6
The non-intrinsically safe end of the transmitter must only be connected to devices where there are no voltages higher than 250V.
6)
Special conditions for safe use / Installation instructions for 9739MVD*(1,3)*****.
6.1
The transmitter must be installed outside the hazardous area in such a way that it meets at least the safety requirement IP20 according to IEC 60529.
6.2
The non-intrinsically safe end of the transmitter must only be connected to devices where there are no voltages higher than 250V.
