3.2 inVerter Priority circUit
In this connection mode, the inverter is the primary input. If this input fails the
device will switch to the power from the 230 V mains. As soon as the power
from the inverter is available again, the device will switch back.
An example:
An inverter is the primary supplier of the 230 V (e.g. solar panels). If the power
input from the inverter fails, the device will switch to the Slave input, which could
be a connection to the 230 V power grid. As soon as the solar panels supply
power again, the device disconnects from the 230 V power grid and switches
back to the solar panels input.
– Connect your inverter to the Master (1) connector on the device. The L and
N conductors are connected directly. The protective conductor must be
connected to the PE (3) input.
– Connect the 230 V power input to the Slave (2) connector on the device. The
L and N conductors are connected directly. The protective conductor must be
connected to the PE (3) input.
– Connect the 230 V user/output to the Load (4) connector on the device. The
L and N conductors are connected directly. The protective conductor must be
connected to the PE (3) input.
imPortant notice!
The “Master” input always has a higher priority than
the “Slave” input. If there is a voltage on both inputs, the output and connected
device will always use the “Master” as power source
3.3 switching Delay
You can pre-program the delay time on the switching between Master and
Slave. This will protect sensitive, connected devices. The delay time can be
selected between 0.5 and 20 seconds. Adjustment is made with the variable
potentiometer Switch Delay (5). Turning it fully to the left results in immediate
switching.
