Connecting the UE 2xxB and UR 2xx(D) Compact Inverters
The inverter voltage U
The UR 2xx regenerative compact inverters must be connected to the main
power line via the KDR 120 commutating reactor and the line filter. This is
necessary for keeping the main line free of disruptive higher harmonics.
For power connection, see page 4 – 30.
