Electromagnetic compatibility (EMC) describes the ability of electronic and electrical devices
or systems to work properly in the electromagnetic environment and not to generate
electromagnetic interference that influences other local devices or systems.
In other words, EMC includes two aspects: The electromagnetic interference generated by
a device or system must be restricted within a certain limit; the device or system must have
sufficient immunity to the electromagnetic interference in the environment.
The drive satisfies the European EMC directive 2004/108/EC and the standard EN 61800-3:
2004 +A1: 2012 Category C2. The AC drives are applied to both the first environment and the
second environment.
When applied in the first environment, the AC drive may generate radio
CAUTION interference. Besides the CE compliance described in this chapter, take
measures to avoid the radio interference if required.
The integrator of the system installed with the AC drive is responsible for compliance of the
system with the European EMC directive and standard EN 61800-3: 2004 +A1: 2012 Category
C2, C3 or C4 according to the system application environment.
Definition of Terms
● First environment
Environment that includes domestic premises, it also includes establishments directly
connected without intermediate transformers to a low-voltage power supply network which
supplies buildings used for domestic purposes.
● Second environment
Environment that includes all establishments other than those directly connected to a low-
voltage power supply network which supplies buildings used for domestic purposes
● Category C1 AC drive
Power Drive System (PDS) of rated voltage less than 1 000 V, intended for use in the first
environment
● Category C2 AC drive
PDS of rated voltage less than 1 000 V, which is neither a plug in device nor a movable
device and, when used in the first environment, is intended to be installed and commissioned
only by a professional person.
● Category C3 AC drive
PDS of rated voltage less than 1 000 V, intended for use in the second environment and not
intended for use in the first environment
● Category C4 AC drive
PDS of rated voltage equal to or above 1 000 V, or rated current equal to or above 400 A, or
intended for use in complex systems in the second environment
