4. The DC voltage across the capacitor of the intermediate
circuit on the single-phase power module can be measured to
make sure that the capacitor is not short-circuited. If the
function is correct, the voltage must be ≥ 350 V (at a mains
voltage of 230 V). See fig. 44. If not, the module is defective.
