application
Transmitter operated outside the potentially explosive atmosphere.
Transmitter operated inside the potentially explosive atmosphere.
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.
