  All necessary operational measures must be initiated prior to 

deactivating any safety device in order to perform mainte-
nance, repair or any other work on the unit. 

Safety awareness also entails informing colleagues of any unsuit-
able behaviour and reporting any faults detected to the appropriate 
authority or person.  
The member of personnel responsible for the equipment must 
ensure that: 
  The safety instructions and operating instructions are readily 

available and are complied with 

  The operating conditions and technical data are observed  
  Safety devices are used  
  The prescribed maintenance work is performed  
  Maintenance personnel are informed without delay or the 

equipment is shut down immediately in the event of abnormal 
voltages or noise, high temperatures, vibrations or any similar 
phenomena, so that the cause of this can be determined 

Here you will find information about the additional dangers associ-
ated with photovoltaic systems. 
An active power source is connected. Depending on the operating 
status, the PV cells and the equipment may be live. 
 

 

Risk to life due to electric shock. 


 Do not touch live parts. 



 Wear personal protective equipment ( Chapter 

2.2.3). 

 
Crystalline silicon cells 
Crystalline PV cells (silicon cells) usually have an IT system 
configuration, i.e. a non-earthed system that will be inadvertently 
earthed in the event of an earth fault. 
A generator with a complex branched structure can only be shut 
down with a great deal of difficulty (in the event of a short circuit, 
for example).  

Thin-film cells 
To prevent corrosion, thin-film cells must be earthed. 

Lightning protection 
The desired level of protection can only be achieved if a lightning 
protection zone concept has been implemented for the building 
where the unit is to be installed, in accordance with DIN VDE 
0185-4.
