INTENDED USE

1. 

The power pack 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 power pack (depends on the type). The product has a protection against short circuit and 

overload.

This product fulfils European and national requirements related to electromagnetic compatibility (EMC). 

CE conformity has been verified and the relevant statements and documents have been deposited at 

the manufacturer.

Unauthorised conversion and/or modification of the device are inadmissible because of safety and approval 

reasons (CE). Any usage other than described above is not permitted and can damage the product and lead to 

associated risks such as short-circuit, fire, electric shock, etc. Please read the operating instructions thoroughly 

and keep them for further reference.

We do not assume liability for resulting damages to property or personal injury if the 

product has been abused in any way or damaged by improper use or failure to observe 

these operating instructions. The warranty/ guarantee will then expire!

The  icon  with  exclamation  mark  indicates  important  information  in  the  operating 

instructions. Carefully read the whole operating instructions before operating the device, 

otherwise there is risk of danger.

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.

• 

Miscellaneous

Repair works must only be carried out by a specialist/ specialist workshop.

• 

If you have queries about handling the device, that are not answered in this operating instruction, our

4. 

Periodically check the technical safety of the device, e.g. check for damage to the housing 

etc.

Always lay the cable so that nobody can trip over or become entangled in it. This poses 

a risk of injury.

Connect the DC plug of the power pack with the DC jack on the low-voltage device.

1. 

The polarity cannot be altered. The plug has the fixed polarity „inside plus (+), outside minus (-)“.

2. 

Make sure that the consumer is switched off when connected to the poower pack.

3. 

Plug the power pack into a standard domestic wall socket. Correct operation is signaled at the power pack 

4. 

by a LED.

To remove the consumer, proceed in reverse sequence.

5. 

By purchasing the power pack 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

Solution
