phase or during operation. For this purpose, a signal is transmitted from the
primary inverter with built-in data manager to the secondary inverters (Lite
devices).
The function is activated as soon as the data manager fails or the Solar Net con-
nection is interrupted. In this case, the signal is not transmitted to the secondary
inverters. All devices switch off with status 710.
The following requirements must be met to enable the Fail-Safe to function cor-
rectly:

Correct wiring
Function in the event of a fault
Faults occur at the beginning and end of the Solar Net ring – the primary invert-
er stops sending the signal, and secondary inverters switch off with status 710.
