7.1 Information about the EMC law according to CE-guidelines
On 1st January 1996 the EMC law (Electromagnetic Consistency) came into force for the
European Community. The EMC law has special requirements regarding radiation noise,
conducted noise, surge immunity and harmonic oscillations. To keep to the regulations in
the industrial area (class A) concerning ultrasonic humidifiers, a power supply filter and/or
a condenser - depending on the type of humidifier - has to be connected to the primary of
the transformer. (From now on the relevant parts will be supplied loose with the delivery.
This applies for deliveries within the European Community.). This simple modification is
only necessary for new installations. A retrofit of existing installations is not necessary.
CE - Declaration of Conformity
When the following interference suppressing methods are carried out, all STULZ Ultrasonic
humidifiers essentially meet the EC-guideline 89/336/EEC, as well as the regulations of
the harmonized norms EN 55011, EN 60555 and EN 50082-2.
If the units are used wrongly and/or the technical manual and the measures which are
described here are not followed, this declaration becomes invalid.
Interference Suppressing Method ENS 1200 to ENS 9600:
To fulfil the EMC requirements, two condensers (class Y) 0,22 µF (part no.: M25114) have
to be connected on the primary of the transformer (see diagram below).
