All wiring must be In accordance with local and national electrical codes and should be undertaken by
an experienced and qualified electrician.
Always use dust/liquid tight flexible metal conduit with approved fittings to protect the sensor cables.
Use rigid metal conduit to protect the cables from the sensors to the control unit. Conduit systems can
channel water due to ingress and condensation directly to sensors and sensor connections which over
time will adversely affect the performance of the system. As such, the installation of low point conduit
drains is recommended for all sensors.
The unit connections and typical wiring diagrams are given in figures. 1, 2 and 3. The contacts are
voltage free and there is no connection between L (+) and the relay, until links are installed as required
(see figures. 2 and 3).
Cable length can be extended to virtually any distance required. The sensor is well protected against
electrical interference, but if long cable runs are used in very noisy environments, the cabling should be
segregated from any high current carrying conductors.
NOTE: The startup delay is initiated by applying power.
