4.5 Installation Overview
Fig. 10. Install Overview.
4.6 Check Polarity of the Current Sensor.
Verify all phases are loaded by at least 1% of meter rated load, and check the polarity
of the sensors.
Test the sensors wires one pair at a time, verifying polarity, phase rotation and
correspondence to line input. Safety guards must be in place.
CAUTION: High voltage - extra care must be taken.
Fig. 11. Sensor Polarity. When current sensor is installed properly, error LED is off. If
the Error LED is illuminated, then disconnect the gray plug and reverse the input lead.
If it clears, the “Sensor Error” then mark appropriately. Repeat for all sensors.
