Class 2 circuits are energy-limited circuits with a maximum voltage of
AC 30 V or 42 V, a maximum current of 5 A and a maximum power of
100 VA.
Safety in accordance with Euro-
pean standards – CE
EMC: Interference immunity
EMC: Emission interference
The permissible environmental conditions for the transmitter unit
and receiver unit may differ from those of the junction box. In such
instances, compliance with the limit values of all modules must be
guaranteed by means of a suitable spatial arrangement on site.
If the junction box is set up outdoors, measures must be taken
where necessary to ensure the intended operation. This may in-
clude rain canopies, for example, or housings offering an adequate
degree of protection if necessary.
