- The buzzer only sounds while the inverter is being supplied with
power from the solar modules.
- The relay remains in its switched position, even when the DC supply
is terminated due to the onset of darkness.
- A service code can only be acknowledged (and the relay reset) when
the DC supply is available.
- The buzzer sounds briefly while the inverter is starting up - this is a
standard part of the initialisation routine and does not indicate a mal-
function.
Fronius Signal Cards may be used with inverters from serial number
14330071.
A hardware update is required for older inverters. Please contact your
installation engineer for further information.
