sensor module must always be connected to that terminal off which the power supply cable is lead through current sensor.
7. Supply 24 VAC power to the sensor module. Any class II transformer with 24 VAC output can be used. The sensor module needs 3 VA
power input. The transformer is available as an accessory.
8. Connect the crankcase heater to the sensor module (optional). The sensor module has a relay to control the crankcase
heater (only 120/240 VAC).
