SAFETy INSTRUCTIONS
Before commissioning, please observe all the items in this guide. The power supply is only gu-
aranteed to function properly if the instructions are followed thus providing you with maximum
satisfaction with your DARK POWER PRO
P9
product.
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 authorized person-
nel. 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 if necessary, 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 off!
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 sufficiently ventilated by means of additional fans; with today’s complex
and powerful systems an ATX-compatible 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. Opening the device will void your
warranty.
Before using the power supply, allow it to warm up to room temperature for one hour to prevent condensation
accumulating in the power supply.
