The lightning flash with arrowhead symbol, within an

equilateral triangle is intended to alert the user to the

presence of uninsulated “dangerous voltage” within the

product’s enclosure that may be of sufficient magnitude to

constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is

intended to alert the user to the presence of important

operating and maintance (servicing) instructions in the

literature accompanying the appliance.

servicing the appliance.

2. Use of a mains separator transformer is mandatory during maintenance while the appliance is opened, needs  to be 

operated and is connected to the mains

3. Switch off the power before retrofitting any extensions, changing the mains voltage or the output voltage.
4. The  minimum distance between parts carrying mains voltage and any accessible metal piece (metal enclosure),

respectively between the mains poles has to be 

3 mm

 and needs to be minded at all times.

The  minimum distance between parts carrying mains voltage and any switches or breakers that are not connected 
to the mains (secondary parts) has to be 

6 mm

 and needs to be minded at all times.

5. Replacing special components that are marked in the circuit diagram using the security symbol (Note) is only permissible

when using original parts.

6. Altering the circuitry without prior consent or advice is not legitimate.
7. Any work security regulations that are applicable at the location where the appliance is being serviced have to be strictly

obeyed. This applies also to any regulations about the work place itself.

8. All instructions concerning the handling of 

MOS

 - circuits have to be observed.

Note:
