INSTALLATION AND ELECTRIC CONNECTIONS
The M SG BOX RST modules can be fixed to the wall, using the proper plastic brackets inserted in
the holes placed on the box rear side corners. These brackets can easily rotate to reach 90°.
The light curtain must be connected to the respective connectors M12 (Fig.1) using the dedicated
cables.
The cables coming out from the cable gland (PG11) must be connected - depending on its
utilization - to the connectors CJ1, CJ2 and CJ3. Terminal tightening torque: 4,4lb-in (0,5 Nm) is
mandatory.
Use 60/75°C copper (Cu) conductor only. Wire size range: AWG 12÷30, (solid/stranded) (UL).
