User manual TRONIC KH 3901 VOLTAGE TRANSFORMER

[. . . ] 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. This device suitable only for use indoors. [. . . ] Do not use the power inverter in vehicles whose plus pole is connected to the vehicle body and/or the chassis. The positive pole must be inside the 12 V receptacle. Do not use the power inverter in vehicles with positive earth 12 V receptacles. The power inverter is equipped with a residual current protection switch, which by residual currents >3mA at the safety contacts of the 220 240 V socket, switches the power inverter off. If this should happen immediately remove the device connected to the power inverter and under no circumstances should you connect this device to any other power supply!The device is defective and must be examined and if necessary repaired by a specialist before it can be put back into service!Before connecting a load/device to the power inverter make sure that the on/off switch 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 of the power inverter. Switch the power inverter on by moving the on/off switch to the position I. If the power inverter is functioning properly the operation LED/Overload indicator will light up green. 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. 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. Reposition the power inverter, television, antenna cable and antenna until reception improves. [. . . ] In the case of a warranty claim, please make contact by telephone with our service department. Only in this way can a post-free despatch for your goods be assured. The warranty covers only claims for material and maufacturing defects, not for wearing parts or for damage to fragile components, e. If this product has been subjected to improper or inappropriate handling, abuse, or modifications not carried out by one of our authorised sales and service outlets, the warranty will be considered void.
