Maintenance and Cleaning
Apart from an occasional cleaning or exchanging the fuse, this laboratory power supply is maintenance-
free. Use a clean, lint-free, antistatic and dry cloth to clean the device. Do not use any abrasive or
chemical agents or detergents containing solvents.
Exchanging the fuse
If it is no longer possible to switch on the laboratory power supply, the rear mains fuse (17) is probably
defective.
Proceed as follows to replace the mains fuse:
Switch off the power supply unit and remove all connecting cables from the unit. Pull the mains plug from
the mains socket.
Using a suitable screwdriver, depress the fuse holder (17) on the rear side a little, and remove it with a
quarter-turn anti-clockwise rotation (bayonet cap).
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 “Technical Data”.
While pushing, screw the fuse plug clockwise back into the fuse holder.
