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.
