Safety 

o No changes may be made to the device, otherwise the CE mark will be removed.  
o The EM-box may only be connected by qualified electricians.  
o Before connecting the EM-box, the battery leads must be disconnected. Ensure that the polarity of the batteries is 
correct!     
 
These installation and operating instructions are part of the component delivery. It must be kept in a safe place - 
important for later maintenance work - and passed on to any subsequent owners of the EM-box.   
 

Exclusion of liability 

 philippi elektrische systeme cannot monitor compliance with the operating instructions or the conditions and methods 
of installation, operation, use and maintenance of the EM-box. Therefore, we do not assume any responsibility and 
liability for loss, damage or costs resulting from incorrect installation and improper operation.   
 

Warranty  

We provide a warranty for the delivered equipment based on our "General Terms and Conditions - Section 7". These 
terms and conditions are the basis of all sales and delivery offers, they are printed in our catalogues and attached to 
all offers and order confirmations.  
 

CE mark  

This device meets the requirements of the EU directives: 2014/30/EC "Electromagnetic compatibility" The conformity 
of the device with the above directives is confirmed by the CE mark. 
 

Intended use 

The EM-box serves as a high current distributor for battery systems with a nominal DC voltage of 12V or 24V and 
must be installed in dry locations.
