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�
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 suciently 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�
