4.7.8 Connecting status signalling contact (optional)
The S series string inverters are equipped with a status signalling contact for remote
monitoring as a standard. The inverter status can be detected with the potential-free relay
contact. The contact is located on the front of the device between the DC and AC con-
nections (see 4.7.2 “Overview of the electrical connections”). How the status signalling
contact works can be set in the “Settings” menu (see section 6.4.2.6).
Setting Functionality
Off The status signalling contact is deactivated (remains idle).
Mains The status signalling contact NO closes immediately during mains opera-
tion and is opened again when the set delay time expires, as soon as the
device ceases to feed.
Error The status signalling contact closes when the set delay time expires as
long as a malfunction, an error or an alarm is activated during this time.
The relay opens immediately as soon as the error no longer exists.
Events which could trigger the status signalling contact are listed in the
section 10.2 “Diagnosis & corrective steps”.
