Schüco inverters are equipped with a potential-free alarm relay as standard. The re-
lay can be designed as a make-contact element or as a break-contact element and
is actuated for all malfunctions signalled by the device. This ensures fast, reliable in-
dication of a possible fault in the PV system on site. For PV systems with several So-
lar Inverters the individual relays can be switched in parallel and connected via a
common indicator lamp.
The master also signals faults from other units in the CAN network via the alarm re-
lay. It is therefore sufficient for simple alerting to connect the alarm relay of the mas-
ter.
CAUTION
The alarm relay is designed for 230 V / 2 A. Higher outputs/voltages can result in the
relay being destroyed. The connected signalling unit must be fused separately. The
terminals are intended for a cable cross-section of 0.2 mm
mensioning the cross-section, also take the current consumption of the connected
signalling unit into account.
