8 Operation
Switching ON and Power Saving
Move the main switch to position I (ON) or II (POWER SAVING).
Power saving mode scans the output and compares the detected load to the threshold value (40W). If a
load is detected which is below the threshold value, the inverter switches to power saving mode. If a
load is detected higher than the threshold value, the inverter is switched on.
Switching OFF
Move the main switch to the position O (OFF). Note that switching off the AC Master does not
disconnect the batteries!
