User manual TRONIC KH 3905 POWER INVERTER

[. . . ] This safeguard may not in any way be circumvented or changed. Arrange for defective plugs, connection terminals or cable to be replaced at once by qualified technicians or our Customer Service Department. Get customer service to repair or replace connecting cables and/or devices that are not functioning properly or have been damaged. You may not open the casing or repair the device yourself. [. . . ] Do not use the power inverter in vehicles with positive earth receptacles. Loosen the red screw on the power inverter as much as is needed for you to be able to place the red cable shoe of the 12 V vehicle cable C with the opening under the screw and washer. (See diagram: Cable shoe connection) · Turn the red screw so tight that the cable shoe can no longer become unattached. Loosen the black screw on the power inverter as much as is needed for you to be able to place the black cable shoe of the 12 V vehicle cable C with the opening under the screw and washer. Turn the black screw so tight that the cable shoe can no longer become unattached. The power inverter can also be operated when the engine is switched off. However be aware that the power inverter possibly may not function during an engine startup. Before connecting the power inverter to a voltage source make sure that the on/off switch e on the device is in the position 0. You can connect the power inverter with the 12 V plug C to a 12 V in vehicle receptacle or attach directly to an automobile battery with the connection terminals B . For both connection variants the connection cable must be connected to the power inverter's 12 V connection screw t. Due to high crossover resistances heating of the plug in connector can result when using the cables with a 12 V vehicle plug C . Therefore when operating with high loads use the connection cable with the connection terminals B . Loosen the red screw on the power inverter as much as is needed for you to be able to place the red cable shoe of the red cable with the connection terminal B with the opening under the screw and washer. Turn the red screw so tight that the cable shoe can no longer become unattached. Loosen the black screw on the power inverter as much as is needed for you to be able to place the black cable shoe of the black cable with the connection terminal B with the opening under the screw and washer. Turn the black screw so tight that the cable shoe can no longer become unattached. First connect the red terminal clamp to the plus pole of the automobile battery and then the black terminal clamp to the minus pole of the battery. 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 w will light up green. When switched on a short signal tone can be heard. If a signal tone can be heard and the operation LED/ Overload indicator w lights up red the input voltage is too low or the power of the load/device connected to the power inverter is too high. 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. [. . . ] 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. Never submerse the device in water or other liquids! Do not allow any liquids to penetrate the housing. [. . . ]
