7.13.2 Emission Requirements
According to the EMC product standard for adjustable speed drives EN/IEC 61800-3:2004, the EMC requirements depend on
the environment in which the drive is installed. These environments along with the mains voltage supply requirements are
defined in
.
The drives comply with EMC requirements described in IEC/EN 61800-3 (2004)+AM1 (2011), category C3, for equipment
having greater than 100 A per-phase current draw, installed in the 2
nd
environment. Compliance testing is performed with a
150 m (492 ft) shielded motor cable.
