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 replaced.
WARNING!
Risk of electric shock.
An electric shock can be fatal. Before opening the device:
▶
Move the mains switch to the "O" position
▶
Unplug the device from the mains
▶
Put up an easy-to-understand warning sign to stop anybody inadvertently
switching it back on again
▶
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.
This can result in serious injury and damage to property.
▶
The housing screws provide a suitable ground conductor connection for eart-
hing the housing and must not be replaced by any other screws that do not
provide a reliable ground conductor connection.
IMPORTANT! If an error message that is not described here appears on the dis-
plays, then the fault can only be fixed by After-Sales Service. Make a note of the
error message shown in the display and of the serial number and configuration of
the power source, and contact our After-Sales Service team with a detailed de-
scription of the error.
