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
dened in Table 7.15.
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.
