Handling PV modules 

3.1 

 Intended use 

 

 

3.1.1  

Appropiate use 

 
PV modules are used for generating electrical power in 
stationary photovoltaic systems which are connected 
to the grid. If you would like to use the PV modules for 
another purpose, such as for charging an accumulator 
directly, you may need additional components (e.g. 
string diodes). PV modules are suitable for installing 
near livestock farms and coastal regions. 
Observe all the applicable legislation, regulations, 
guidelines and standards when installing and operating 
the modules. 
 
3.1.2  

Inappropriate use 

 

 

 

• Do not install PV modules on vehicles and do not 
  use them in air, space or seafaring applications. 
• Do not use PV modules if they are exposed to con- 
  centrated sunlight or strong artificial light, or if they 
  could be immersed in water or other liquids or  
  exposed to vapour. 
 
3.1.3  

Product-specific information 

 
Product-specific information (e.g. the data sheet) con-
tains details of a particular type of PV module. 
Only use PV modules for the intended purpose out-
lined in the product-specific information. 
Data sheets may change without prior notice. If the 
information in the data sheet differs from this manual, 
the data sheet takes precedence. 
 

3.2 

 Personal protection 

 

3.2.1  

Electrical safety precautions 

 

High DC voltages during storage, installation,  
operation and maintenance. 
Risk of fatal electric shock! 
 

• PV modules may only be installed by qualified 
  technician with a high level of expertise.
