Electrical Installation
5.5 Electromagnetic compatibility
The MOVITRAC
®
LTP range of frequency inverters is designed for use in machines and
drive systems. They comply with the EMC product standard EN 61800-3 for variable
speed drives. For EMC compliant installation of the drive system, follow the guidelines
set out in council directive 2004/108/EC (EMC).
5.5.1 EMC immunity
The MOVITRAC
®
LTP range meets the immunity levels defined in EN 61800-3 for both
industrial and domestic (light industrial) environments.
5.5.2 EMC emissions
The MOVITRAC
®
LTP EMC emission levels comply with the limit classifications defined
in EN 61800-3 and EN 55014, allowing it to be used in both industrial and domestic (light
industrial) applications.
To obtain the best EMC performance the drives should be installed in accordance with
the wiring guidelines in chapter "Installation" on page 18, thereby ensuring good earth
connections for the drive system. Screened motor cable must be used to achieve
compliance with the radiated emissions levels.
