d) Circuit-breaker opening
Press the push-button “O” (1) to open the circuit-breaker in the manual mode. When there is a shunt opening release, the operation can also
be carried out in the remote mode by means of the special control circuit. The open state is signalled by the appearance of the letter “O” in the
indicator (3).
c) Circuit-breaker closing
This operation can only be carried out when the closing springs are fully loaded.
Press the push-button (5) marked with the letter “I” for closing in the manual mode. When there is a shunt closing release, the operation can also
be carried out in the remote mode by means of the special control circuit. Closing is signalled by the relative indicator (3), which moves to the
“I” position. Moreover, the indicator of the state of the springs (6) moves to the WHITE position. The control has enough energy for the opening
operation even when the closing springs are unloaded. If present, the gearmotor immediately begins the automatic spring loading operation.
