b) Miscellaneous
• Consult an expert when in doubt about operation, safety or connection of the device.
•
Maintenance, modifications and repairs are to be performed exclusively by an expert or at a
qualified shop.
• If you are not sure about the correct connection or use, or if questions arise which are not co-

Operation
Ensure the polarity is correct when establishing a connection. The positive terminal of
the cable is identified by a white line and a sticker showing a +.
Ensure the power supply unit’s open ends are insulated with suitable insulating material
at all times. This applies to the power supply unit whether it is installed or not.
Always unplug the power plug first before disconnecting the connectors from the consu
-
mer.
1. LEDs and LED strips already feature soldering points where the power supply unit’s open ends can be
attached. Ensure the polarity is correct. After assembly, insulate the connections with suitable insulating
material such as heat shrink tubing.
2. Set the required voltage (3 / 4.5 / 5 / 6 / 7.5 / 9 / 12 V/DC) with the key.
3. Connect the mains plug to a standard mains socket (100 – 240 V/AC, 50/60 Hz).
4. Remove the power adapter from the mains when it is no longer in use.
Cleaning
• When cleaning, the power adapter must be disconnected from mains socket.
• Only use dry and soft cloth to clear the housing of the power adapter.
• Do not use abrasive or solvents.
