5.2 eMc requirements (electromagnetic compatibility)
The EMC requirements depend on the intended use.
class B environment (en 61800-3: class c2)
Environment that includes domestic premises, it also includes establishments directly connected without in-
termediate transformers to a low-voltage power supply network which supplies buildings used for domestic
purposes. Examples of class B environments include houses, apartments, commercial premises or offices in a
residential building.
caution: The relevant EMC regulations for which the HYDROVAR was tested in class B environments is based
on the restricted use of the product and the following limitations:1) the drive voltage is less than 1000 V; 2) it
is neither a plug in device nor a movable device and, 3) when used in the class B environment, it is intended to
be installed and utilized by technicians with the necessary training and skills required for installing and/or using
power drive systems, including specific training with respect to EMC requirements.
class a environment (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 build-
ing fed from a dedicated transformer are typical examples of class A environment locations.
the HYdroVar complies with the general eMc regulations and is tested according to the following
