User manual TRONIC KH 3906 VOLTAGE TRANSFORMER

[. . . ] When connecting the power inverter make sure that the polarity of the vehicle plug matches the polarity of the 12 V in vehicle receptacle. The socket must have an internal positive pole, that is to say that the positive pole of a vehicle battery cannot be connected to the chassis of the vehicle. You may not open the device casing or repair the device yourself. Should you do so, the safety of the device may be compromised and the warranty becomes void. [. . . ] The positive pole must be inside the 12 V receptacle. Do not use the power inverter in vehicles with positive earth 12 V receptacles. Usually on the device's rating plate you can find information regarding the power consumption in amperes (A) or the wattage (W). Before operation make sure that the maximum power consumption does not exceed 0, 65 A and the maximum continuous load is not more than 150 W. Loads with a high internal resistance operate very well with the power inverter, on the other hand, loads with a low internal resistance, for example heating and cooking devices have a power consumption in watts that is too high. Inductive loads, for example, televisions or stereo systems (devices with an inductor or a transformer) often require a much greater switch on current than resistance loads with the same specified wattage. When switching on, television sets demand much more power than that indicated on the rating plate. Therefore it may be necessary to switch the power inverter on and off several times in order to switch the television set on. Most heat producing devices, for example, hair dryers, clothes irons or heating fans can not be operated via the power inverter because the power consumption of these devices exceeds the output power of the power inverter. Before connecting a load/device to the power inverter make sure that the on/off switch e on the device is in the position 0. Make sure that the power of the load/device to be run that you intend to connect to the power inverter does not exceed the continuous load rating specified in the power inverter's technical data. Insert the plug of the connecting load/the device to be operated into the 220 - 240 V socket r of the power inverter. Switch the power inverter on by moving the on/off switch e to the position I. If the power inverter is functioning properly the operation LED/Overload indicator t will light up green. When the battery runs low (under 11 V) a continuous signal tone sounds to indicate that the battery needs to be charged. The operation LED/Overload indicator t continues to light up green. When the battery voltage drops below 10 V the power inverter switches off and the operation LED/Overload indicator t lights up red. Reduce the load until you no longer exceed the maximum load as specified in the technical data. Maintain the input voltage of the power inverter above 11 V to keep the output voltage constant. The power inverter is shielded and puts out a filtered sine wave. With the reception of, for example, very weak television stations it can, nevertheless, result in interferences and/or image breakdown. In this case position the power inverter as far away as possible from the television, antenna cable and antenna. [. . . ] The warranty is void in the case of abusive and improper handling, use of force and internal tampering not carried out by our authorized service branch. Your statutory rights are not restricted in any way by this warranty. The warranty period will not be extended by repairs made under warranty. this applies also to replaced and repaired parts.
