User manual GRAUPNER SWITCHING POWER SUPPLY 5-15V 0-20A

[. . . ] the voltage button " "will show the set voltage on screen. Then turn the Amp knob to get your needed max current cut off point, Amp button " " will show you the value. Read thoroughly the following contents before using. Disconnect the power supply from AC mains power before connecting device to the power supply. [. . . ] The charger and the battery to be charged should be set up on a heat-resistant, noninflammable and non-conductive surface before use. Never place the charger directly on a car seat, carpet or similar. Keep all inflammable and volatile materials well away from the charging area. The charge output sockets and connecting leads must not be modified, and must not be inter-connected in any way. There is a danger of short-circuit between the charge outputs and the vehicle's bodywork when the charger is connected to the car battery. The charge leads and connecting leads must not be coiled up when the charger is in use. Avoid shortcircuiting the charge output or the model battery with the car bodywork. For this reason the charger must never be placed directly on the vehicle's bodywork. Never leave the charger running or connected to the car battery unsupervised. Only one battery may be connected at each output at any one time. The following types of battery must not be connected to the charger: · Ni-Cd / Ni-MH batteries, lead-acid batteries with a nominal voltage of more than 12V or less than 6V, Lithium-Ion / Li-Mn / Lithium-Polymer / LiFePO4 (LiFe) batteries with less than 2 cells and more than 3 cells (4 cells for LiFePO4). Batteries which require a different charge method from CC/CV or lead-acid types. Batteries consisting of old and new cells, or cells of different makes. Batteries which are not expressly stated by the manufacturer to be suitable for the currents which this unit delivers during the charge process. Packs which are already fully charged or hot, or only partially discharged. Batteries installed in a device, or which are electrically connected to other components. To avoid short-circuits between the banana plugs fitted to the charge leads, please always connect the charge leads to the charger first, and only then to the battery to be charged. As a basic rule always check that the charge quantity is approximately the same as you expected after the charger has indicated that the pack is fully charged. This is a simple method of detecting a problem reliably and in good time, should the charge process be terminated prematurely for any reason. The likelihood of premature termination varies according to many factors, but is at its highest with deep-discharged packs, low cell counts and particular cell types which are known to cause problems. We recommend that you carry out a series of test charges to satisfy yourself that the automatic termination circuit is working perfectly. This applies in particular when you are charging packs consisting of a small number of cells.
