4 Mounting
Mount the sensor and the reflector using suitable mounting brackets (see the SICK
range of accessories). Align the sensor and reflector with each other.
Note the sensor’s maximum permissible tightening torque of < 0,4 Nm.
5 Electrical installation
The sensors must be connected in a voltage-free state. The following information must
be observed, depending on the connection type:
– Male connector connection: Pin assignment
– Cable: Wire color
Only apply voltage/switch on the voltage supply once all electrical connections have
been established.
