3.3.4 Wiring and EMC guidelines
For effective interference suppression, do not route power and control cables in the same
conduit or trunking.
To prevent radiated noise, motor cable should be put in a metal conduit. Alternatively an
armored or shielded type motor cable should be used.
For effective suppression of noise emissions the cable armor or shield must be grounded at
both ends to the motor and the inverter ground. These connections should be as short as
possible.
Motor cable and signal lines of other control equipment should be at the least 30 cm apart.

All BDI50-...-F inverters are equipped with an internal EMC filter able to comply the
performance levels required by EN 61800-3:2012 standard (category C2) with a maximum of
