3.1 MAINS PRIORITY CIRCUIT
In this connection mode, the 230 V mains source is the primary input. If this input
fails (e.g. 230 V power input to a camper), the device will switch to the power
input from the inverter. (e.g. internal battery in the camper ). As soon as the main
input of 230 V is applied again, the device will automatically switch back.
– Connect your 230 V power source 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 inverter to the Slave (2) connector on the device. The L and N
conductors are connected directly. The protective conductor must be con-
nected 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.
