[X02] DC bus

DANGER

Danger to life from electric shock!

After switching off the mains, the buffer capacitors for the DC bus can still have a charge and lead to a life-threatening DC voltage.

Steps to prevent:

  • After switching off, expect a discharge time of at least 5 minutes.
  • Measure the voltage in the DC bus between the UZP / UZN terminals to ensure that the terminals are voltage-free.
  • Caution: A voltage-free state is not signalled!
