COOLING FAN OPERATION
To save energy, the cooling fan starts when the power supplied from the inverter exceeds the 30% of maxi-
mum power, or when the internal temperature exceeds 60°C.
POWER CONSUMPTION OF ELECTRIC EQUIPMENTS
Most electrical equipments have a rating label that indicates the nomianal power consumption. Ensure that
power consumption of the electrical equipment to be operated is less than the nominal power of the inverter.
This last, automatically shuts down the output if the demanded power exceeds the maximum power that it
can provide (see
TECHNICAL CHARACTERISTICS
).
Resistive loads are the easiest for the inverter to power. Nevertheless, higher resistive loads such as electric
stoves or heaters usually requires a starting power much bigger than the nominal one. Inductive loads, such
as electric motors or sound systems, can require an actual power much greater than that of resistive loads
of the same nominal power. In particular, induction motors can require a starting power from 2 to 6 times
their nominal power. Among inductive loads, the most demanding starting power are those that start under
load, such as for instance electric pumps and compressors.
Remark.
If the inverter is used to power a compressor or an air conditioning, it is always advisable to wait 3/5
minutes between one ignition and the next so that the pressure inside the compressor chambers balances.
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 (
IRS3000-12
), or19V DC (
IRS3000-24
) (see
Table 1
and
TECHNICAL CHARACTERISTICS
).
• 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-sufficient 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
•
Do not use the inverter near flammable materials and gas.
• After a prolonged use the temperature of inverter housing can be high, thus do not touch the inverter
when it is heated.
• To prevent damages to the USB port, do not connect devices requiring a current greater than the maxi-
mum supplied by the port.
• In case of doubts, malfunctions or breakdowns, contact the dealer where you purchased the inverter.
