application Permissible voltage range of power supply
Transmitter operated outside the potentially explosive atmosphere. 11 … 42 V
Transmitter operated inside the potentially explosive atmosphere. 11 … max. 30 V (intrinsically safe)
WARNING! Risk of explosion!
If, when using transmitters with type of protection "intrinsic safety", an ammeter is connected to the output circuit
or a modem is connected in parallel while there is a risk of explosion, the sums of the capacitances and
inductances of all circuits, including the transmitter (see EC-type-examination certificate) must be equal to or less
than the permissible capacitances and inductances of the intrinsically safe signal circuit (see EC-type-examination
certificate for the power supply unit).
Only passive or explosion-proof devices or indicators may be connected.
