Approvals and Conformity 

TÜV Rheinland Product Safety GmbH,  performed 
the CE - type examination according to the machin-
ery directive EC/98/37, appendix VI and the respec-
tive standards ICE 61496. 
 
The CE - conformity declaration and the product ap-
proval certification (TÜV) is available at your nearest 
CEDES dealer or on the homepage 
www.cedes.com. 
 
 
 

 

Warning 

Safe2+ or Safe4 systems are only a safety protection 
device if all instructions in this manual and in the 
related documents are carefully followed and fully 
complied with. In addition the installer is responsible 
to comply with all local laws and standards. 
 
If these instructions are not (or only partially) fol-
lowed, this may lead to serious injury or even death 
and legal action against the responsible installer or 
system integrator. In such a case claims against 
CEDES are not valid. 
 
This instruction manual is part of the light curtain 
Safe2+ or Safe4. It must be kept accessible during 
the whole life cycle for everybody who is in charge of 
installation, operation, maintenance and safety con-
trol.
