Safety Instructions
The warranty will be void in the event of damage caused by non-compliance
with these safety instructions. We do not assume any liability for any resulting
damage!
We shall not accept liability for damage to property or personal injury caused
by incorrect handling or non-compliance with the safety instructions. The
warranty will be void in such cases!
• The unauthorised conversion and/or modifi cation of the product is not permitted for
safety and approval reasons (CE).
• The device is designed according to Protection Class I. Only a standard safety
mains socket connected to the public supply grid may be used as the voltage
source.
The outlet must be located in direct proximity to the device and easily accessible.
• The product must not become damp or wet; it is only intended for use in dry, indoor
locations.
• Do not place containers, such as glasses, vases or plants, on or alongside the
computer. Liquids may seep into the casing and thus impair the electrical safety of
the device. Furthermore, there is a signifi cant risk of fi re or a lethal electric shock!
In such an event, switch off all poles of the mains socket to which the product is
connected (switch off automatic fuse or remove the fuse, switch off RCD) and then
pull the mains plug out of the mains socket and the power adapter. Afterwards, the
power adapter can no longer be used; take it to a specialist workshop.
• If you take the power adapter (or the computer in which the power Adapter is
installed) from a cold room in to a warm room, condensation may form. Allow the
power adapter (and the computer into which the power adapter is installed) to
reach room temperature f before connecting it to the mains voltage and switching
it on. This may take several hours. Otherwise, not only may the power adapter or
the computer be destroyed, but there is also the risk of a life-threatening electric
shock!
• Do not handle the power adapter, computer, mains cable and mains plug with
damp or wet hands. Otherwise there is the risk of a fatal electric shock!
• Do not pull on the power adapter's cable to unplug it from the mains socket!
• Do not touch the mains cable if it shows any signs of damage. First switch off all
poles of the mains socket to which the product is connected (switch off automatic
fuse or remove the fuse, switch off RCD) and then pull the mains plug carefully out
of the mains socket. Finally, replace the mains cable with a new one with the same
technical specifi cations. Do not attempt to repair a damaged mains cable!
• The product is not a toy and should be kept out of the reach of children. Children
cannot judge the risks that can arise due to the incorrect handling of electrical
appliances. Take particular care when children are around, as they may try to stick
objects into the unit through the openings in the housing. There is danger of a life-
threatening electric shock!
• Do not leave packaging material carelessly lying around, since it could become a
dangerous plaything for children.

Functional Description
The power adapter is intended to be used on the mains voltage (see section "Technical data").
The power adapter converts this mains voltage into the internal direct current required by the
PC (+3.3 V, +5 V, +12 V, -12 V).
A built-in fan expels the excessive heat that is formed during this transformation.
The power adapter can be switched on and off via the power switch.
When the computer is switched off using the power button, stand-by voltage is still present on
the motherboard.
This is needed, for example, to turn on the computer via keyboard or mouse (if the BIOS of your
computer provides for this option).
Therefore, if you wish to work inside the computer (e.g. to install a new plug-in card), always
switch off the power supply unit fi rst using the mains power switch; then remove it from the
mains voltage. Always pull the mains plug out of the mains socket! Otherwise, the motherboard
as well as other components could be damaged!

Installation

• Open your computer's housing and carefully remove the cover.
• If the power adapter is to be used, for example, to replace an old, defective, power adapter,
remove the existing power adapter fi rst. First of all, disconnect all connecting plugs from the
motherboard and the installed devices. Then remove any cable ties that may be present.
• Grip the old power adapter tightly and remove all the retaining screws from the power adapter
so that it can be removed from the housing.
• Screw the new power adapter into place in the housing with 4 screws (inch thread, max.
screw length ca. 5 mm).
• Connect to the motherboard with the broad ATX power plug (do not use force! The connec-
tor must be easy to plug in and then lock in place). Depending on your motherboard (20 or
24 pin. socket), a 4-pin segment can be removed from the 24-pin ATX connector. However,
the latter must not be used for other connections on the motherboard!
• A 4-pin connector on the motherboard serves to provide the 12 V supply voltage to supply
the voltage regulators on the CPU. However, never connect the above-mentioned 4-pin plug,
removed from the 24-pin ATX connector, here; instead, use the separate 4-pin ATX connector
of the power adapter intended for this purpose.
• Connect all devices in the PC housing to the appropriate power plugs, e.g. hard drive, DVD
burner, graphics card, etc.
• Install all of the cables neatly in straight lines, ensuring that the cables are not squeezed or
damaged in any way. Protect the cables from sharp edges inside the housing. Make sure that
they do not become entangled in the fan of the computer.
• Use cable ties to secure the cables inside the housing.
• Check the following points: Is the power button on the front of your ATX housing connected
to the appropriate port on the motherboard?
• Close the computer housing and re-connect the computer to all other devices, cables and
accessories.
• Now, connect the computer to the mains voltage and switch on the power adapter via the
mains switch on the rear of the power adapter (switch setting "I").
• In commercial institutions, the accident prevention regulations of the Employer's
Liability Insurance Association for Electrical Systems and Operating Facilities are
to be observed.
• In schools, educational centres, hobby and self-help workshops the operation of
the product is to be supervised by trained employees.
• If you have any questions that are not answered in this manual, please contact our
technical service or another specialist.
However, the computer does not start when the power switch is switched on.
Initially, both the power adapter and the connected motherboard are in the so-called
"standby" mode. To start the computer, briefl y press the power button on the front of
your PC housing. The button must be connected via a cable to the corresponding
connection on your motherboard (e.g. "ATX power" connection or similar; see the
instructions for the motherboard).
If you do not have the expertise to install the device correctly, please contact an
expert or a specialist workshop and let them carry out the installation!
In case of improper installation, both the power supply unit and your computer and
all connected devices will be damaged. Furthermore, there are dangers involved
such as short circuit, electrical shock or the risk of fi re.
Switch off the computer in which the power supply unit is to be installed and all con-
nected devices and separate all devices from the mains voltage. Unplug the mains
plug! Just switching off at the mains switch is not suffi cient!
Switching on via the mains switch does not result in the computer being switched on
(this may be changed via the BIOS setting); see section "Description of Function".
The computer will normally not start up immediately. Briefl y press the power button
on the front of your PC housing to switch the computer on.
