Latch Operation
Press down on the side tab and swing the top of the unit up to open the split core current switch as shown in Figure 2.
Press down firmly on the cover to close the
current switch. An audible “click” will be heard as the tab slides over the
tongue on the base.
CAUTION
Mating surfaces of the magnetic core are exposed when the sensor is open. Electrical contact grease, present
on the cores to prevent corrosion, can capture grit and dirt if care is not exercised. Operation can be impaired if anything
prevents good contact between pole pieces. Visually check the mating parts of the core before closing the current sensor.

LED
The Red LED will indicate whether the current is above (LED On) or below (LED Off) the fixed trip point. At very low
monitored input currents the Red LED may not light to indicate the current is above the trip point.
