• Do not pull the mains plug from the mains socket by pulling the cable Always pull the plug from the
mains socket by the gripping area provided on the side. Otherwise the power cord may get damaged,
risk of an electric shock!
• The ATX power supply unit must not be opened! There are no serviceable parts inside the ATX
power supply unit.
• If the ATX power supply unit (or the computer in which it is installed) is not used for a longer period
of time (e.g. if it is in storage) then switch it off via the mains switch and additionally pull the mains
plug of the power cord form the mains socket.
• If you only switch off the computer via the power button on the front of the computer housing, then
the computer or the power supply unit is in "standby" mode (similar to a television).
This is why the computer must be separated from the mains voltage before retrofitting work is done
onto your computer (e.g. when inserting a plug-in card). Switch the ATX power supply unit off via the
mains switch and separate it from the mains voltage; pull the mains plug.
• The ATX power supply unit has (although it is low) a power input in "standby" mode. This is why a
slight warming is normal.
Per month there are quite a few kWh (kilowatt-hours) that accumulate in the "standby" mode.
Depending on the price of electricity this means costs of maybe about 1-2 Euro per month that can
be easily saved. Simply switch off the ATX power supply unit via the mains switch if the computer
is no longer needed.
Of course, the same is valid for other products without own mains switch, e.g. TFT monitors,
computer speakers etc.
10. Maintenance and Cleaning
There are no serviceable parts in the ATX power supply unit, this is why you should never open it. Any
maintenance or repair and the ensuing opening of the ATX power supply unit may only be carried out
by an expert or a specialist workshop.
The fuse which is installed in the ATX power supply unit must be replaced with a special tool only. This
is why you should not try to replace the fuse yourself, leave this to an expert or a specialized workshop.
Due to the fan that is built into the ATX power supply unit, the computer will suck in more or less dust in the course
of time, depending on the installation site, which will settle inside the power supply unit and on the fan blades. This
dust can be removed with a vacuum cleaner from the outside.
Separate the ATX power supply unit from the mains voltage beforehand, pull the mains plug!
To clean the outside of the ATX power supply unit, a dry, soft and clean cloth is sufficient.
