Important: 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 supply unit). Only passive or explosion-proof devices or indicators may be connected.
