x Residual current I0 (5 A input: terminals X1: 9-10, 1 A input:
terminals X1: 7-8)

Further the relay can collect position information and alarm
signals via the digital input (terminals X2: 4-5) and store the
information in the event register.
The digital input can be used to:
x Block protection stages under certain conditions.
x Get time stamped event code from any auxiliary
contact.
x Control the output relays.
x Supervise the trip circuit.
