4.   Installation 

 

  The safety of this light fitting is only guaranteed as long as it is operated within its 

assessment threshold. Installation and maintenance must be done in accordance with 
the respective regulations! 

 

  The installation of explosion-proof light fittings must be done by Ex-skilled electricians 

only! 

 

  In regard to the minimum and maximum admissible ambient temperature potential 

sources of cold and heat (e.g. direct heat or solar radiation, cooling units) have to be 
considered! 

 

  The application of this light fitting in an explosive dust atmosphere is depending on the 

properties of the surrounding dust. Please ensure that there will be an adequate 
difference between the maximum surface temperature of the fitting and the glowing and 
the ignition temperature of the respective dust! 

 

  If there is a risk of accidental electrostatic charge the light fitting must be protected by 

appropriate measures! 

 

  The light fitting must be mounted in the instructed operation position (see Chapter 3, 

Technical Data)! 

 

4.1   How to open the light fitting 

 

 

 

 

 

 

Open clamp lockings by hand. 

 
 
 

 

 
 

 
 

 

 
 
 

 

 

 

 

 

 

  

 
 
 

 

 

 

 
 

 

 

 

 

       

 

               

 

There is a safety closure at each
