In FR12 (12-pulse drive) or in FR12 (6- or 12-pulse) with internal brake, the DC-links between units are connected together. If connected together,
there must be DC-link fuses in DC-minus and DC-plus poles between the units. (In 6-pulse drive without internal brake, DC-links between units are
separate and there is no need for fuses.)
