OUTPUT AC VOLTAGE MEASUREMENT
The power inverter provides an AC output voltage with a modified sine waveform. The multimeters commonly
available on the market are only suitable to measure pure sine wave voltages. Usually, these multimeters
provide a measure of the output voltage 20 or 30V lower than the actual RMS value. Therefore, to measure
the RMS of the output voltage is necessary to use a multimeter/voltmeter able to measure the RMS value of
non-sinusoidal waveforms.
PRECAUTIONS AND WARNINGS
•
To avoid damages, when turning on or turning off the engine of your vehicle, the inverter must be
switched off.
•
To prevent damages, disconnect the inverter from the batteries before recharging them by a battery
charger.
•
To avoid completely discharging the battery, keep the engine of your vehicle running when using the
inverter.
•
Ensure that the battery voltage does not exceed the permitted limits.
•
Before making any connections make sure that the inverter and the appliances to be connected are
turned off.
•
If the inverter activates the buzzer, which indicates a low input voltage, disconnect the inverter and re-
charge the batteries. In any case, in order to not completely discharge the batteries, the inverter shuts
off automatically when the input voltage falls below
9.5V DC (
IRSxxxx-12
), or 19V DC (
IRSxxxx-24
)
(see
Table 1
and
TECHNICAL CHARACTERISTICS
).
•
Some equipments, such as measuring instruments, precision tools and switching power supplies
equipped with a PFC circuit may not work with a modified sine waveform. In these cases we recom
-
mend the use of a pure sine wave inverter.
•
There are no parts to be maintained by the user inside the inverter.
•
Keep clean from dust and dirt the outer parts of the inverter, especially the ventilation holes of cooling
fan.
•
Ensure that the inverter is well ventilated, do not obstruct the ventilation holes on the casing nor the
hole of cooling fan.
•
To avoid electric shock hazards or injuries keep the inverter out of reach of children and non self-suffi
-
cient people.
•
To avoid electric shock hazards use the inverter in indoor and dry environments away from water and
any other kind of liquid.
•
Do not open the inverter neither try to insert objects or materials of any kind.
•
Any modification to the inverter can generate hazards and voids any guarantee.
•
When necessary, replace the inverter fuse with one having the same characteristics.
•
Don’t try to access into the inverter, there is
potentially lethal electricity.
•
To prevent damages and electric shock hazards, do not try to connect 220V AC sources to the inverter.
