5.1.8.1. High-speed double-pole power outputs (HSPO)
The high-speed power outputs PS1_4_HSPO1... PS1_4_HSPO5 and
PS2_4_HSPO1...PS2_4_HSPO7 can be connected as double-pole outputs where the
object to be controlled, for example a circuit breaker, is electrically connected
between the two relay contacts, see the § below. The high-speed double-pole power
output is recommended to be used for tripping purposes.

The high-speed power outputs PS1_4_HSPO1... PS1_4_HSPO5 and
PS2_4_HSPO1...PS2_4_HSPO7 can also be connected as single-pole power
outputs where the object to be controlled, for example a circuit breaker, is
electrically connected in series with the two relay contacts, see the figure below.
