The high-speed power outputs PS1_4_HSPO1... PS1_4_HSPO5 can also be
connected as single-pole power outputs where the object to be controlled (e.g. a
circuit breaker) is electrically connected in series with the two relay contacts, see the
figure below.

5.1.8.2. Single-pole power outputs (PO)
The single-pole power outputs BIO2_7_PO1 and BIO2_7_PO2 are outputs where
the object to be controlled is connected in series with two heavy-duty output relay
contacts, see the figure below. These outputs can be used for tripping purposes and
for circuit breaker and disconnector control.

Double-pole power outputs (PO)
The double-pole power outputs BIO2_7_PO3... BIO2_7_PO6 are outputs where the
object to be controlled (e.g. a circuit breaker) is electrically connected between the
two relay contacts, see the figure below. These outputs can be used for tripping
purposes and for circuit breaker and disconnector control.
