INTENDED USE
The product serves as voltage supply for low-voltage devices with matching DC jacks. It is intended
for connection to common household mains voltage (100 - 240 V/AC, 50/60 Hz). A galvanic separated
DC voltage is applied to the output. The power consumption of the consuming device many not
exceed the nominal voltage of the respective product (depends on the type). The product has a
protection against short circuit and overload.
For safety and approval purposes (CE), 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 cause hazards such as short circuiting, fire, electric shock etc. Read the
instructions carefully and keep them. 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 personal injury or
damage to property. Such cases will invalidate the warranty/guarantee.
a) Persons / Product
• The product is not a toy and should be kept out of reach of children!
• When used in conjunction with other devices, observe the operating instructions
and safety notices of connected devices.
• The product must not be subjected to heavy mechanical stress.
• The product must not be exposed it to extreme temperatures, direct sunlight,
intense vibration, or dampness.
• Never touch the device with wet or moist hands. There is a danger of electrocution.
• On commercial premises, the accident prevention regulations of the relevant
professional insurance association for electrical systems and operating materials
are to be observed.
• Operation in unfavourable ambient conditions is not permitted. Adverse ambient
conditions are:
- moisture or excessive humidity
- dust and combustible gases, vapours or solvents
• Since the device generates heat when operating, ensure that it is adequately
ventilated. The housing must not be covered!
• If you have reason to assume that safe operation is no longer possible, then
disconnect the device immediately and secure it against inadvertent operation. It
can be assumed that safe operation is no longer possible if:
- the device is visibly damaged,
- the device no longer functions
- it has been stored for long periods of time under unfavourable conditions or
- it has been subject to considerable stress in transit.
• Never switch the device on immediately after having taken it from a cold to a warm
environment. Under adverse conditions, the resulting condensation could destroy
the device. Allow the device to reach room temperature before switching it on.
• Power units are not designed for application to human beings or animals.
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 covered by these
operating instructions, please do not hesitate to contact our technical support or another qualified specialist.

OPERATION
Periodically check the technical safety of the device, e.g. check for damage to the
housing etc.
Always lay the cables so that nobody can trip over or become entangled in them.
This poses a risk of injury.
1. Connect the DC plug of the power supply with the DC jack on the low-voltage device.
2. The polarity cannot be altered. The plug has the fixed polarity „inside plus (+), outside minus (-)".
3. Make sure that the consumers are switched off when connected to the power supply.
4. Connect the power cord's low-voltage plug with the matching connector of the power supply unit.
5. Connect the power cord's mains plug to a standard mains outlet.
6. Correct operation is signaled at the power supply by a LED.
7. To remove the consumer, proceed in reverse sequence.
TROUBLESHOOTING
By purchasing the power supply you have acquired a product that has been designed to the state of
the art and is operationally reliable. Problems and malfunctions can occur nevertheless. We would
therefore like to show how you can rectify certain faults yourself:
Observe the safety instructions by all means!
Problem Cause
No mains voltage.
The power indicator
is not lit.
Power supply overloaded.
DISPOSAL
Electronic devices are recyclable waste and must not be disposed of in the household
waste.
At the end of its service life, dispose of the product according to the relevant statutory
regulations.
