Control Circuit Without DC Bus Short Circuit (ZKS) for HMV01.1R
Supply Units Without Integrated Mains Contactor
Observe Off delay and pick-up delay of K1!
Off delay K1:
Select K1 mains contactors with an Off delay shorter than the On
delay t
d_on
of the DC bus short circuit device. Otherwise, the DC
bus short circuit device switches on with applied mains voltage
and causes tripped fuse (F1) or damage to the supply unit.
Circuits for overvoltage protection increase the Off delay. Ob‐
serve the data of the selected mains contactor!
Pick-up delay K1:
Select K1 mains contactors with a pick-up delay of less than
100 ms. Otherwise, the error message F2835 will be generated.
