EMC requirements (Electromagnetic compatibility)
The EMC requirements in general differ between two environments which depending on
the intended use.
•
First environment – class B
(EN 61800-3: Class C2)
Environment that includes domestic premises, it also includes establishments directly
connected without intermediate transformers to a low-voltage power supply network
which supplies buildings used for domestic purposes e.g. houses, apartments, commercial
premises or offices in a residential building are typical examples of first environment
locations.
Be careful: The relevant EMC regulations for which the HYDROVAR is tested in the first
environment consider that the HYDROVAR is a restricted available product. That means the
voltage of the inverter is less than 1000 V, it is neither a plug in device nor a movable
device and, when used in the first environment, is intended to be installed and
commissioned only by a person or an organisation having necessary skills in installing
and/or commissioning power drive systems, including their EMC aspects.
•
Second environment – class A
(EN 61800-3: Class C3)
Environment that includes all establishments other than those directly connected to a low
voltage power supply network which supplies buildings used for domestic purposes e.g.
Industrial areas, technical areas of any building fed from a dedicated transformer are
typical examples of second environment locations.
The HYDROVAR complies with the general EMC regulations and is tested according
to the following standards: EN
61800-3/2004
EN 55011
