Exchanging the fuse If it is no longer possible to switch on the laboratory power unit, the rear mains fuse (12) is probably defective. Proceed as follows to replace the mains fuse: 1. Switch off the power unit and remove all the connection cables and the mains plug from the device. 2. Lever the rear fuse holder (12) with a suitable screwdriver from the bracket. 3. Replace the defective fuse with a new fine-wire fuse (5 x 20 mm) of the same type and rated current. The fuse value is listed in the chapter on “Technical Data”. 4. Press the fuse into the fuse holder. Fuses are replacement parts and not covered by the warranty/guarantee. 15.Troubleshooting By purchasing the laboratory power unit, you have acquired a product that is reliable and operationally safe. Nevertheless, problems or errors may occur. For this reason we want to describe how to troubleshoot potential malfunctions: Always follow the safety instructions!

Connected consumer devices do not work. • Is the voltage set correctly? • Is the polarity correct? • Check the technical data of the consumers. The “REAR CONTROL” display is lit.
