6.1.2 Multifunction relay X100 Interface
Application:
The multifunction relay can be configured in two ways:
I.1.1
As an alarm relay. In the event of an inverter fault, the alarm signal is connected.
I.1.2
As a load relay. It will be connected above a defined threshold power generated by the inverter and can be used,
for example, to control a contactor with an external power supply connecting a household consumer.
Wiring:
A number of signals can be operated in parallel as long as the maximum current of 1 A and
24 V is not exceeded.
