High-speed double-pole power outputs (HSPO)

The high-speed power outputs PS1_4_HSPO1 ... PS1_4_HSPO5 can be connected as
double-pole outputs where the object to be controlled (e.g. a circuit breaker) is electri-
cally connected between the two relay contacts, see the figure below. The high-speed
double-pole power output is preferred to be used for tripping purposes.
e.g.
PS1_4_HSPO1...
PS1_4_HSPO5

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.
e.g.
PS1_4_HSPO1...
