5.1.8.2. Single-pole power outputs (PO) and a high-speed single-pole

power output (HSPO)

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

following figure. These outputs can be used for tripping purposes and for circuit

breaker and disconnector control.

5.1.8.3. Double-pole power outputs (PO)

The double-pole power outputs BIO2_7_PO3... BIO2_7_PO6 are outputs where the

object to be controlled, for example a circuit breaker, is electrically connected

between the two relay contacts, see the following figure. These outputs can be used

for tripping purposes and for circuit breaker and disconnector control.
