Troubleshooting
General The digital power sources are equipped with an intelligent safety system. This means
that apart from the fuse for the coolant pump, it has been possible to dispense with melt-
ing-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.
Safety
WARNING!
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!
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.
