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
Safety in accordance with U.S.
and Canadian standards – UL,

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.
