Components for EMC compliant installation
MOVIDRIVE
®
drive inverters and regenerative power supply units are designed for use
as components for installation in machinery and systems. They comply with the EMC
product standard EN 61800-3 "Variable-speed electrical drives." Provided the informa-
tion relating to EMC-compliant installation is observed, the devices satisfy the appropri-
ate requirements for CE-marking of the entire machine/system in which they are fitted,
on the basis of the EMC Directive 89/336/EEC.
MOVIDRIVE

compact
MC_4_A drive inverters size 1 and 2 are fitted with a line filter
as standard. These units comply with class A limit to EN 55011 and EN 55014 on the
line side without further measures.
Interference
immunity
With regard to interference immunity, MOVIDRIVE
®
meets all the requirements stipu-
lated in EN 61000-6-2 and EN 61800-3.
Interference
emission
Higher levels of interference are permitted in industrial environments. In industrial envi-
ronments, it may be possible to dispense with the measures listed below depending on
the situation of the supply system (mains) and the system configuration.
