Maintenance and Cleaning

Apart from an occasional cleaning or exchanging the fuse, this laboratory power unit is maintenance-

free. Use a clean, lint-free, antistatic and dry cloth to clean the device. Do not use any abrasive or chem-

ical agents or detergents containing solvents.

Exchanging the fuse

If it is no longer possible to switch on the laboratory power unit, the rear mains fuse (26) is probably

defective.

Proceed as follows to replace the mains fuse:

Switch off the power unit 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 (9) on the rear side a little, and remove it with a quar-

ter-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 technical data.

While pushing, screw the fuse plug clockwise back into the fuse holder.
