Troubleshooting
Safety The digital power sources are equipped with an intelligent safety system - which has
made it possible to dispense with melting-type fuses entirely. After a possible malfunction
or error has been remedied, the power source can be put back into normal operation
again without any fuses having to be changed.
WARNING!
Danger of electrical shock.
An electric shock can be fatal. Before opening the device
▶
Turn the mains switch to the "O" position
▶
Unplug the device from the mains
▶
Ensure the device cannot be switched back on
▶
Using a suitable measuring instrument, check to make sure that electrically charged
components (e.g. capacitors) have been discharged
WARNING!
Danger from inadequate ground conductor connection.
An inadequate ground conductor connection can cause serious injury or damage.
▶
The housing screws provide a suitable ground conductor connection for earthing the
housing. The housing screws must NOT be replaced by any other screws that do
not provide a reliable ground conductor connection.
If any error message that is not described here appears on the displays, then the fault is
