Bolt the new power supply unit firmly onto your PC housing with 4 bolts (inch-measure thread, length
of thread max. approx. 5mm).
The power supply unit has a wider ATX plug than that of conventional power supply units. This is for
connection to appropriate mainboards (e.g. servers).
For connection to a conventional mainboard with 20-pole ATX connection, the adapter
cable provided (24-pole to 20-pole) is always to be used.
The 24-pole ATX plug must not be directly inserted into the 20-pole connection of the
mainboard! This would destroy the power supply unit, the mainboard and also all other
connected PC components!
Connect the 24-pole ATX plug of the power supply unit with the 24-pole socket of the adapter cable,
then plug the 20-pole plug of the adapter cable into the 20-pole socket of the mainboard.
Warning!
If forced the ATX plug can also be plugged the wrong way round onto the connection on the
mainboard! It must be possible to plug the ATX plug in lightly and to then click it cleanly into
place with the clip on the side.
The PC-ATX power supply unit also has a 4-pole ATX2.0-12V plug which is necessary for many Intel-
P4 mainboards.
The matching connection on the mainboard is for connecting the +12V voltage to the mainboard via
extra lines, which is intended to relieve the load on the +12V line of the ATX current plug.
If your mainboard has this connection, always make sure that you connect it with this plug.
The 8-pole plug (2 rows with 4 contacts) can only be connected to corresponding mainboards (e.g.
servers). With conventional mainboards, the connection has no function.
Connect all of your devices with the suitable current plugs, e.g. hard drive, DVDROM etc.
Lay all the cables into your PC cleanly and straight, making sure that the cable is not crushed or otherwise
damaged. Protect the cable from the sharp edges in your PC housing. Make sure that they do not get
into the fan of the PC.
Use binders to fix the cables.
Check: is the power button on the front of your ATX housing connected with the corresponding
connection on the mainboard?
Switching on at the power switch does
not
normally lead to the switching-on of the PC (can
possibly be activated/set in the BIOS of the main board)!
Close the housing of your computer and connect it up once more to your other devices and accessories.
Connect your computer to the mains voltage and switch the ATX power supply unit on.
The computer does not normally start yet. Press briefly upon the power button on the front of your ATX
housing in order to switch the PC on.

7. Servicing and Cleaning
Regularly check the technical safety of the power supply unit, e.g. damage to the power cord or to the housing.
If it is to be assumed that safe operation is no longer possible, then the power supply unit is to
be put out of service and made secure against unintended use. Pull the mains plug from the
socket!
It is to be assumed that safe operation is no longer possible if
-
if the device shows visible damage,
-
if the device no longer functions or
-
after a long period of storage under unfavourable conditions or
-
after heavy demands from transportation.
Before cleaning or servicing the device, always follow the following safety instructions:
There are no parts within the device which are to be maintained by the user.
Live parts can be exposed when opening covers or removing parts.
Before cleaning, servicing or repair the device must be separated from all voltage sources; pull
the mains plug out! Switching off at the power switch isnt enough!
Capacitors in the device can still be live, even if the device has been separated from all voltage
sources.
Repairs may only be carried out by skilled personnel who are familiar with the risks involved and
the relevant regulations.
The built-in instrument fuse is only to be replaced using a special tool. Therefore, do not try to
replace the fuse yourself; leave this to a technical workshop.
A dry, clean, fibre-free cloth suffices for cleaning the exterior of the housing.
The dust which has gathered on the power supply unit and the fan blades can be removed using a vacuum
cleaner.
