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.

be observed, depending on the connection type:
– Male connector connection: Note pin assignment
– Cable: wire color
Only supply/switch on the voltage once all electrical connections have been estab‐
lished.
