1.5.2 - Standards (Emission)
The maximum emission level is set by the generic industrial (EN 50081-2) and residential (EN 50081-1) standards.
VARMECA 30 conforms to the following standards:
EN 50081-2, EN 61000-6-4 - EN 61800-3, IEC 61800-3.
The second environment includes industrial networks supplied with low voltage but which do not serve buildings
for domestic use. Operation of a drive without an EMC filter in this type of environment may result in interference
on certain electronic appliances located near the drive whose immunity level might not be compatible with industrial
conditions. If it proves impossible to filter the disturbed element, add an external EMC filter.
