Safety issues 

Observe national safety 

directives and regulations 

for the electrical engineer-

ing trade, in particular: 

IEC 60335-2-69 

EN 60335-2-69 

DIN VDE 105 part 1: 

operation of electrical 

power installations. 

DIN VDE 0701/0702: 

repair, modification and 

testing of electrical installa-

tions.

Before starting the equip-

ment, be sure to read the 

accompanying user 

manual, and keep it close 

as reference. 

The equipment should 

only be used by persons 

who have been instructed 

in its use and are author-

ized to do so.

Repairs should only be 

made by someone who has 

received proper instruc ons 

for the job or who is a quali-

fed electrician.

  

 

WARNING: 

The upper sec on of the 

machine contains live com-

ponents. Contact with live 

components leads to seri-

ous or even fatal injuries. 

Always disconnect the 

mains plug before disassem-

bly. 

For your own safety.

ESD (electrosta c discharge) 

Observe the following ESD precautions before any 

repair of or near electronic parts: 

• Touch the protective conductor to discharge your own body.

• Possibly wear an anti-static wrist strap.

• Use a conducting floor or tabletop.

• Never touch a circuit board or electronic components - always hold them by the

plastic or insulation.

• Transport electronic parts in conductive packaging (e.g. special ESD packages).
