1.8 Signal contact
Figure 2: Signal contact: 2-pin terminal block with screw locking
The signal contact is a potential-free relay contact. 
The device allows you to perform remote diagnosis via the signal contact. In 
the process, the device signals events such as a line interruption. When an 
event occurs, the device opens the relay contact and interrupts the closed 
circuit. The management setting specifies which events switch a contact.
You can also use the management to switch the signal contact manually and 
thus control external devices.
