Configuration
5.5.2.1.
High speed double-pole power output (HSPO)
The high-speed power outputs PSC_7_HSPO1 and PSC_7_HSPO2 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 figure
below. The high-speed double-pole power output is preferred for the control of
disconnectors.

PSC_7_HSPO2
The high-speed power outputs PSC_7_HSPO1 and PSC_7_HSPO2 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 Fig. 5.5.2.1.-2 .

Signalling output (SO)
The signalling output is not a heavy-duty output and thus it cannot be used for
controlling a disconnector without external interpose relays. Available SO contacts
are either Normally Open or Normally Open/Normally Closed type contacts (NO or
NO/NC), see the figure below.
