Power supply unit
• Connect the power supply via the terminal block on the power supply unit as shown overleaf. Live supply to the L terminal,
Neutral to the N terminal and the load to the LIVE OUT (L/out) terminal.
• Connect the sensor head to the power supply unit using the RJ11 connector, ensuring it “clicks” in place.
• In the case of dimming applications, connect the D+ and D_ connections to the corresponding terminals on the luminaire
dimming ballast.
• On power up, the load should come on immediately.
• Vacate the room or remain very still and wait for the load to switch off (on the factory preset, this should take approximately
15 minutes, but the timing out period can be adjusted down to 1 minute to help speed up the setup procedure — please
see next section for details on set-up & adjustment).
• Check that the load switches on when movement is detected.
