Mechanics & Installation Instruction of the RED00202
Stable metal/aluminium housing IP20. To allow adequate convection, a free air space of 50mm (top/bottom)
and 10mm (sidewalls) is required; and for active devices 15mm space from the sidewalls. For proper air
convection it is necessary to install the RED. One can use the DIN-Rail installation (equipped standard) with our
patented 35mm DIN-Rail bracket according to EN60715. It is easy to mount/dismount while snaping it onto the
35mm DIN-Rail - no tools necessary. The housing screws are recommended for the GND-connection – do not
remove them. For operation >60Vdc a GND-connection to PE is necessary to prevent from any kind of
interferences to the supply system.
It is not allowed to install the RED00202 in other mounting direction then below drawings.
