X 2.2 com.
•
X 2.3 n.c.
n.c. - com. closed in the event of malfunction or power failure
n.o. - com. closed during normal operation
(closed current principle)
The contacts X2.1 - 2.3 are potential-free.
External test / remote control:
•
X 3.1 external test (IN1)
•
X 3.2 GND
Contacts connected = test active = discharge
Contacts open = test inactive
The contacts X 3.1 -3.2 are not potential-free.
