6.7.2 Using digital output pv reduction
The digital outputs cannot be used directly. Additional relays are required,
which are not included in the scope of delivery.
Using the PV reduction digital outputs - PV reduction 1 and 2 - is a good idea if
the feed-in power of the PV system must not exceed a fixed value (feed-in limit).
