1. INTRODUCTION
We are delighted that you have chosen to use a be quiet! power supply from our Dark Power Pro 11 series in
your PC. Please read and follow all the information contained in these instructions carefully prior to installation.

Manufacturer's details�
2. SAFETY INSTRUCTIONS
The power supply is only guaranteed to function properly if the instructions are followed.
Caution: Only use the supplied cable set. Using cables that were not included (e.g. cables of older power
supply unit series) may lead to defects!
Never open the power supply case. The electronic components inside the case generate a high voltage that is
dangerous to humans. Even after disconnecting the power supply from the network, some parts still have high
voltages. For this reason, a power supply adapter should only be opened by an authorised technician.
Opening the device voids your warranty.
∙ Never handle the power supply with wet or damp hands when in operation.
∙ Never insert objects into the power supply’s apertures/fans.
∙ Note that the power supply is designed for use indoors in conditions without high levels of moisture in the
ambient air. Using the power supply outdoors will lead to serious damage.
∙ Never work on the power supply while it is connected to the mains. In this case, always set the power switch
to "0" and / or disconnect the power plug.
∙ In the event of a short circuit in the device, unplug the mains cable and do not use the device.
Important: Only press the “Overclocking Key” when the power supply is switched o!
Make sure that your PC is not located directly next to a heating system or any other source of heat.
Make sure that your computer case is suciently ventilated by means of additional fans; with today’s complex
and powerful systems a power supply is incapable of dissipating the heat produced in the PC case without
additional support.
If you want to clean your power supply, disconnect it completely from the mains and never use a damp cloth or
cleaning agent. Clean the power supply from the outside using a dry cloth.
Before using the power supply, allow it to warm up to room temperature for one hour to prevent condensation
accumulating in the power supply.
