ELECTROMAGNETIC COMPATIBILITY INFORMATION
Guidance and manufacturer’s declaration – electromagnetic emissions
The BY 40 is intended for use in the electromagnetic environment specified below. The customer or the user of the
BY 40 should assure that it is used in such an environment
Emissions test Compliance Electromagnetic environment – guidance
RF emissions CISPR 11 Group 1 The BY 40 uses RF energy only for its internal function. Therefore, its
RF emissions are very low and are not likely to cause any interference
in nearby electronic equipment.
RF emissions CISPR 11 Class B The BY 40 is suitable for use in all establishments Including domestic
and those directly connected to the public low-voltage power supply
network that supplies buildings used for domestic purposes.
Harmonic emissions
IEC 61000-3-2
Class A
Voltage fluctuations/ flicker
emissions IEC 61000-3-3
