When connecting the battery, there's a spark (Danger of explosion!), because of the charging of the internal
condensator. Check that the cables are well adjusted. As long as it is possible, do not extend the cables supplied with the
batteries. Extending them may increase the losses and cause malfunction of the inverter.
Once the inverter is connected to the batteries, a 230 V tension is present in the outlet of the inverter.

Control and indicators
Control switch on/off
There is a switch on the inverter to activate or deactivate it. Use this function to save the energy of the batteries when
you are not using the inverter.
Green indicator
A green light on the inverter indicates its function mode:
Off:
the 230 V tension is NOT present in the outlet, the inverter is off.
Illuminated:
a 230 V tension is present in the outlet, the inverter is on.
Blinking:
failure has disappeared (see the failure table).
Acoustic indicator
The ONS inverter has an acoustic indicator for the following instances:
Intermittent beep: there is a failure in the inverter and the outlet tension will be interrupted.
Possible failures:
Overheat: the acoustic indicator beeps 3 ºC before cutting the tension. If the temperature reach its normal level, the
tension in the outlet is not interrupted.
Low battery tension: the indicator beeps for a minute before the interruption. If the tension of the battery rises, the outlet
tension is not interrupted.
Continuous beep for two seconds: you have pressed the ON/OFF switch to restart the inverter. The tension in the outlet
will be immediately present after the acoustic signal.
Models with standby system
The ONS inverter with a power of 400/500 W and more are equipped with a standby system witch is in function when
no load are connected. In that situation the inverter is in low power consumption mode.
The output tension is not continuously present and the LED is blinking as long as no load is detected.
The minimal load detected can be adjusted between 1 and 20 W. In most case this adjustment is not necessary. This
adjustment is made with a small screw driver in the hole marked standby. In the full counter clockwise position, the
sensibility is minimal (20 W). Do not push on the screw driver.
NOTE : in this mode the output tension is intermittently present at the output
Safety
The inverter is electronically protected. But protection against polarity inversions of the battery occurs with an internal fuse,
except for 2000W/12V inverter, which has no fuse. The following table will show you the different failures and their
consequences.
