KEB COMBIVERT F5 Betriebsanleitung Seite 51

Note to connection 2 x 3 ph
Supply: 2 x 3 x 305 - 500V
60° electrically shifted
The monitoring switch of the main protection must be connected to the
power-off chain or disconnect the control release!
The B12 rectifier wiring effects a reduction of the network reactions in case of large
power ratings. General information for the generation of a network, to which a B 12
rectifier wiring can be connected, is specified in the following.
The voltages of the two subnetworks (basic reference is in each case the phase L1)
are electrically shifted by 60 degrees. For the set up of such a network (with one or
several inverters) following transformers are used:
One transformer with 2 secundary systems:
Vector group D d0 y11
Two transformers with one system each:
Vector group Y y0
Vector group Y d11
The primary-side star connection is selected for direct medium voltage supply,
at 690V or 400V feed-in it also operated with D y0 and D d11.
