10 A03470_07_E00_00 HBM: public DMP41
Electromagnetic compatibility
The DMP41 has been tested based on EMC product standard EN
61326-1:2013. This standard includes definitions of limit values and test
levels for various electromagnetic environments.
Regarding emission (EME), requirements are included for class A (industrial
environments) and class B (residential, business and commercial
environments as well as small businesses). Laboratory applications also
usually require class B.
The product standard here references to EN 55011:2009+A1:2010.
Regarding immunity to interference, the product standard includes require
ments for controlled electromagnetic environments (lowest requirements),
general environments and industrial environments (highest requirement).
The DMP41 satisfies the following requirements:
S Emission (EME): Class B (see Note)
S Immunity to interference: Industrial environment
Note on emission (EME): The DMP41 is supplied ex works i.a. with a mains
cable and an adapter cable (USB to RS232). These cables are fitted with
ferrites to minimize emission (EME) and must not be removed. The require
ments of Class B are only satisfied when the ferrites are fitted.
Should the ferrites have been inadvertently removed, they must be attached
to the cables as close as possible to the DMP41.
