3. Operation

3.1. On/Off/Charger-only switch

When switched to "on", the product is fully functional. The inverter will come into operation and the LED "inverter on" will light up.
An AC voltage connected to the "AC in" terminal will be switched through to the "AC out" terminal, if within specifications. The
inverter will switch off, the "Charger" LED will light up and the charger commences charging. If the voltage at the "AC-in" terminal
is not within specifications, the inverter will switch on.
When the switch is switched to "charger only", only the battery charger of the Multi will operate (if mains voltage is present). In this
mode input also is switched through to the "AC out" terminal.
NOTE: When only the charger function is required, ensure that the switch is switched to "charger only". This prevents the inverter
from being switched on if the mains voltage is lost, thus preventing the batteries from running flat.

LEDs Description
On / Off / Charger-only switch = On
The inverter is switched on and supplies power to the load.
On / Off / Charger-only switch = On
The inverter is switched on and supplies power to the load. Pre alarm: overload, or battery voltage
low, or inverter temperature high.
On / Off / Charger-only switch = On
The inverter is switched off due to one of the following alarms: overload, battery voltage low,
inverter temperature high, or DC ripple voltage too high.
On / Off / Charger-only switch = On
The AC input voltage is switched through, and the charger operates in float mode.
On / Off / Charger-only switch = On
The AC input is switched through and the charge current is zero. The inverter is switched on
and, in case of PowerAssist, assists the AC input by supplying additional power to the load the
General [4] chapter.
On / Off / Charger-only switch = On
The AC input voltage is switched through. The inverter is switched on and supplies power to the
load or excess power to the mains.
On / Off / Charger-only switch = Charger only
The AC input voltage is switched through, and the charger operates in bulk or absorption mode.
On / Off / Charger-only switch = Charger only
The AC input is switched through, and the charger operates in float or storage mode.
Note: The inverter/charger will shut down if four abnormal events occur within 30 seconds. It can be reset by switching to Off and
then to On again.
