7.10.1 Operation

The inverter is a completely automatic high-efficiency device. The inverter transforms the 24V DC voltage into 230V AC.

• ON, Switch
  Position the ON/OFF switch, located on the front panel of the inverter to “ON”. The green light “inverter on” lights up and the inverter starts.
• OFF, Switch
  Position the ON/OFF switch, located on the front panel of the inverter to “OFF”. The inverter stops and all lit lights switch off.

Warning lights
The functions of the warning lights located on the inverter front panel are:

• Inverter on
  The green light indicates when the inverter is ON.
• Overload
  Light lights up when the inverter is overloaded. When the inverter is overloaded, the power limiter reduces the voltage output.
  According to the load, the inverter will switch OFF after a short period.
• Overload + on slow
  When the inverter remains overloaded for a long period of time, it will switch off and the “overload + on” indicators will blink slowly. This takes approx. 20 seconds, after which the inverter will restart automatically. This is called “wait state” and gives the inverter time to recover from any heavy surge load and gives the battery time to recover in case it is flat.
• Overload + on fast
  The inverter is switched off. When the inverter switches off 10 times with intervals no longer that 30 seconds, the inverter will switch off permanently and the “overload” and “on” indicators will blink fast. To switch the inverter on again, you have to switch the inverter off and on again. When the output terminal is short-circuited, the inverter will overload. The “overload” and “on” indicators will blink slowly. The inverter will try to start up ten times. If the short-circuit is not removed, the inverter will switch off permanently. Remove the short circuit and reset the inverter by switching it on and off.
• Low battery (nearly flat)
  The inverter is OFF when the battery voltage is too low.
  If the voltage increases above certain values, the inverter restart automatically.
• Temperature
  The inverter switches OFF in environments at high temperature and/ or remarkable overload. After the cooling, the inverter starts automatically.

DANGER

When disconnecting the inverter by means of the switch located on the front panel the connection with the mains is not broken off.

DANGER

Do not work on the inverter or on its system if still connected to a current source. Only qualified staff can carry out interventions on the electric system and only after the approval of RIVA.
