The single-pole power outputs BIO2_7_PO1 and BIO2_7_PO2 as well as the high-
speed single-pole power output PS2_4_HSPO8 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.

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.
