Converters size H6 configuration using a FEX-425-Int field exciter 
Wiring the drive according to this diagram offers the highest degree of monitoring functions done by 
the drive. Field converters FEX-425-Int are equipped with their own synchronization and must be 
supplied from independent mains supply voltage max. 500 V (single-phase or 3-phase).
