Servodrives / inverters series COSMOS 301X Installation, use and maintenance manual - EN
4.7 Electromagnetic compatibility (EMC)
The servo-drives/inverters comply with IEC 61800-3 2004-12 requirements; they must be installed in the
second environment, category C3, on the following conditions:
• The connection between the drive and the motor is made by means of an adequately sized shielded
cable.
• The shielded cable must be connected to earth on both sides, with low RF impedance connection
• The motor type and size are suitable for the servo-drive
• The start-up is performed by technical engineers, according to the instructions of this manual.
The integrated filter ensures compliance with the IEC 61800-3, only if a single servo-drive is
operating. The simultaneous operation of more than one servo-drive might increase the
noise level and might exceed the emission levels fixed by the standards. In this case, an
additional filter may be necessary.
These servo-drives are not designed for domestic environment (first-environment, according
to IEC 61800-3 Standards). In this case, it will be necessary to install an additional mains
filter.
The integrated mains filter can be disconnected if the current leakage to earth is not
tolerated. In this case, it will be necessary to install an external low-leakage mains filter.
