The sensor is activated via the display. In
the menu „Settings - Network - Interfac-
es“ you can select the sensor type in the
«Irrad.» and «Temp.» field. Connecting alarm relay
The solar inverters are equipped with a
potential-free alarm relay as standard.
The relay can be designed as a make-
contact element or as a break-contact
element and is actuated for all malfunc-
tions signalled by the device. This ensures
a faster, more reliable indication of a
possible fault in the PV system on site.
For PV systems with several solar invert-
ers, the individual relays can be switched
in parallel and connected via a common
indicator lamp.
The main unit also signals faults from
other units in the CAN network via the
alarm relay. It is therefore sufficient for
simple alerting to connect the alarm
relay of the main unit.
!
CAUTION
The connected signalling unit must be
fused separately! The terminals are in-
tended for a cable cross-section of
0.2 mm
