Filters recommended standard EN 61800-3. For 75 up to from 75 up to 180 A are designed to be 180 A filters, cable length should not exceed 100 compatible with 300 mA RCDs. Install the filter as meters to fulfill class C2. close as possible at line side of the motor drive. Internal EMC/EMI components Regarding correct EMC installation, please refer to Please disconnect all internal Y-capacitors (internal the EMC installation guide in the manual from EMC/EMI filters) in the motor drive, because these motor drive supplier. capacitors cause additional leakage currents. Motor drive Harmonics on line voltage Please set the PWM pulse pattern of the variable High voltage harmonics can create additional speed motor drive fixed to 4 kHz. Other pulse system leakage currents. FN 3268 filters are tested patterns cause higher leakage currents. Filter under following conditions: Supply voltage is designs with other pulse pattern than 4 kHz are contaminated with harmonics according to IEC possible upon request. 61000-2-4, class 2, where odd-numbered multiplies of three are limited to 30%. Typical installation with RCD, EMC/EMI filter and motor drive system RCD Please note that for electrical devices with 6-pulse rectifiers at line input, like three-phase motor drives, a RCD type B or B+ is required. RCD with time delay are needed to prevent unwanted fault trip at switch on or voltage spikes. These RCD types B with time delay have often an added letter S or K, please ask the supplier for correct type. Caution: Please validate system with chosen RCD to guarantee functionality.
