Item No. 2266532
Intended Use
This product is designed to supply USB devices and other electric devices such as notebooks
or netbooks with power, providing six different output voltages to select from. The connected
load's current consumption must not exceed the maximum output rating of the product. Power
is supplied via a standard mains socket. The product should only be used in dry indoor areas.
The product features both short-circuit and overload protection.
It is intended for indoor use only. Do not use it outdoors. Contact with moisture, e.g. in bath-
rooms, must be avoided under all circumstances.
For safety and approval purposes, you must not rebuild and/or modify this product. If you use
the product for purposes other than those described above, the product may be damaged. In
addition, improper use can result in short circuits, fires, electric shocks or other hazards. Read
the instructions carefully and store them in a safe place. Make this product available to third
parties only together with its operating instructions.

Safety Instructions
Read the operating instructions carefully and especially observe the safety
information. If you do not follow the safety instructions and information on
proper handling in this manual, we assume no liability for any resulting per-
sonal injury or damage to property. Such cases will invalidate the warranty/
guarantee.
a) General Information
• The device is not a toy. Keep it out of the reach of children and pets.
• Do not leave packaging material lying around carelessly. This may become dan-
gerous playing material for children.
• Protect the appliance from extreme temperatures, direct sunlight, strong jolts, high
humidity, moisture, flammable gases, steam and solvents.
• Do not place the product under any mechanical stress.
• If it is no longer possible to operate the product safely, take it out of operation and
protect it from any accidental use. Safe operation can no longer be guaranteed
if the product:
- is visibly damaged,
- is no longer working properly,
- has been stored for extended periods in poor ambient conditions or
- has been subjected to any serious transport-related stresses.
• Please handle the product carefully. Jolts, impacts or a fall even from a low height
can damage the product.
• Make sure that the adapter output is not short-circuited.
• Do not touch the power adapter if there are any signs of damage, as this may
cause a fatal electric shock! First, switch off the mains voltage to the socket to
which the mains adapter is connected (switch off at the corresponding circuit
breaker or remove the safety fuse, and then switch off at the corresponding RCD
protective switch, so the socket is fully disconnected). You can then unplug the
power adapter from the mains socket. Dispose of the faulty power adapter in an
environmentally friendly manner and discontinue use. Replace it with a power
adapter of the same design.
• The mains socket must be located near to the device and be easily accessible.
• Only connect the power adaptor to a normal mains socket connected to the public
supply. Before plugging in the power adapter, check whether the voltage stated on
the power adapter complies with the voltage of your electricity supplier.
• The power adapter must never be plugged in or disconnected when your hands
are wet.
• Never unplug the power adapter from the mains socket by pulling on the cable;
always use the grips on the plug.
• When setting up the product, ensure that the cable is not pinched, kinked or dam-
aged by sharp edges.
• Always lay the cables so that nobody can trip over or become entangled in them.
This poses a risk of injury.
• For safety reasons, disconnect the power unit from the mains socket during
storms.
• Never pour any liquids over electrical devices or place objects filled with liquid next
to the product. If liquid or an object does enter the interior of the device, power
down the respective socket (e.g. switch off circuit breaker), and remove the mains
plug from the mains socket. Discontinue use and take the product to a specialist
repair centre.
• Never use the product immediately after it has been brought from a cold room into
a warm one. The condensation generated could destroy the product. The power
adapter may also generate a fatal electric shock! Allow the product to reach room
temperature before connecting it to an appliance. This may take several hours.
• Make sure to observe the polarity and magnitude of the output voltage. Incor-
rect polarity or excessive voltage input leads to the destruction of the connected
electrical appliance.
• Sufficient ventilation is essential when operating the product. Do not cover the
product. Never place the product on a table cloth or on a carpet! Place it on
a hard, flame resistant base.
• Unplug the mains plug from the mains socket under the following conditions:
- Before you clean the product
- During a thunder storm
- If the product is not used over an extended period of time
• Consult an expert when in doubt about the operation, safety or connection of the
appliance.
• Maintenance, modifications and repairs must only be completed by a technician
or an authorised repair centre.
• If you have questions which remain unanswered by these operating instructions,
contact our technical support service or other technical personnel.
b) Connected Devices
• Also observe the safety and operating instructions of any other devices which are
connected to the product.
Operation
Disconnect the power supply unit from the mains socket before replacing the
low-voltage plug or resetting the output voltage.
The power supply unit's output voltage must match the input voltage of the electric
consumer.
USB devices and other electric loads can be operated in parallel. However, make
sure that the power input of the connected devices does not exceed the power sup-
ply unit's total power output.
a) Connecting an electric load
• Set the output voltage on the back of the power supply unit. To do this, slide the switch into
the desired position using a tool (e.g. a screwdriver or tip of a pen). Make sure the switch
engages properly when set into position.
• Select one of the six low-voltage plugs matching the input socket and polarity of the electric
consumer (see table).
• Connect the plug to the connector at the end of the output cable. Voltage reversal of the
output plug is not possible for security reasons. The inner contact is positive (+), the outer
negative (–).
• Connect the low-voltage plug to the switched-off consumer.
• Connect the power cord's low-voltage plug with the matching socket of the power supply
unit.
• Connect the mains plug to a standard mains socket. The LED on the top of the power supply
unit indicates operational readiness.
• Put the power supply unit onto a solid, flame-retardant surface and ensure that the power
supply unit is sufficiently ventilated.
• Now switch the connected consumer on. If it does not function properly, switch it off im-
mediately and disconnect it from the power supply unit.
• Remove the power supply unit from the mains when it is no longer in use.
