Warning

 

 

Before wiring, ensure power to the unit is switched off. Connect the sensor wires to the sensor 

terminals of the transmitter and connect the transmitter’s power and output terminals to the wiring leading to the Power 
source/panel. Refer to the configuration tables below for sensor as well as transmitter power and output terminal 
designations.
