Per CISPR 17; A=50 Ω/50 Ω sym; B=50 Ω/50 Ω asym; C=0.1 Ω/100 Ω sym; D=100 Ω/0.1 Ω sym 

7 to 42 A types 

55 to 100 A types 

130 and 180 A types 

## **Installation** 

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. 

## EMC/EMI filter FN 3268 

Filter types from 7 to 55 A are designed to be compatible with 30 mA RCDs according to IEC 61008 and new VDE 0664-110 standards. Filters from 75 up to 180 A are designed to be compatible with 300 mA RCDs. Install the filter as close as possible at line side of the motor drive. Regarding correct EMC installation, please refer to the EMC installation guide in the manual from motor drive supplier. 

## Motor drive 

Please set the PWM pulse pattern of the variable speed motor drive fixed to 4 kHz. Other pulse patterns cause higher leakage currents. Filter designs with other pulse pattern than 4 kHz are possible upon request. 

## Motor cable length 

Motor cable length should not exceed 30 meters for 7 up to 55 A filter types to fulfill class C1 of recommended standard EN 61800-3. For 75 up to 180 A filters, cable length should not exceed 100 meters to fulfill class C2. 

Internal EMC/EMI components 

Please disconnect all internal Y-capacitors (internal EMC/EMI filters) in the motor drive, because these capacitors cause additional leakage currents. 

## Harmonics on line voltage 

High voltage harmonics can create additional system leakage currents. FN 3268 filters are tested under following conditions: Supply voltage is contaminated with harmonics according to IEC 61000-2-4, class 2, where odd-numbered multiplies of three are limited to 30%.
