7. INVERTER USE
The inverter provides a 230VAC – 50Hz output. The nominal power is 4kW at an engine revolution
speed between 1700 rpm and 3000 rpm.
NOTE
WARNING
The AC output wave distortion (clipping) could increase at lower speed
revolutions.
To prevent electrical shocks from insulation damaged or faulty appliances,
the inverter should be grounded. Connect a braid of heavy copper wire
between the inverter’s heat sink and the external ground source.
Read carefully this manual before using the inverter.
For continuous operation, do not exceed the rated power (see Chapter 11).
In either case, the total wattage of all appliances connected must be
considered.
Do not exceed the specified current and power limits.
A suitable suppressor should be installed as close as possible to the output
terminals to prevent failures caused by coupling of external over voltages on
the output lines.
Substantial overloading that continuously trips the inverter may damage it.
Marginal overloading that temporary happens, may shorten the service life
of the inverter.
Be sure that all appliances are in good working before connecting them to
the generator. If an appliance begins to operate abnormally, becomes
sluggish, or stops suddenly, turn off the generator engine switch
immediately. Then disconnect the appliance and examine it for signs of
malfunction.
Do not connect the inverter to a household circuit. This could cause the
damage to the inverter or to electrical appliances in the house.
Do not modify or use the generator for other purposes than it is intended for.

TARTING
When inverter is power supplied it starts to operate and performs a pre-test procedure lasting about
3 seconds.
If no problem is encountered inverter is ready to start generating.
When a start command is available, start switch must be close (ON position). It is also possible that
pin 7 of connector CON7 stays always grounded, by means of a jumper with pin 10.
The behavior of signalization LEDs is described on paragraph 11.9.
