1. Ensure there is no power to the equipment.
A T T E N T I O N A T T E N T I O N To prevent electrical shock, ensure the main
power has been disconnected before working on
the Hall Effect current sensor. Verify that all
circuits are voltage free using a hot stick or
appropriate voltage-measuring device. Failure to
do so may result in injury or death.
2. Note the location of all wires and the orientation of the Hall Effect
current sensor. For quick reference when checking the orientation
of the Hall Effect current sensor, look for the white arrow.
I M P O R T A N T I M P O R T A N T The Hall Effect current sensor and wires must be
in the proper orientation. Note the position before
disassembly.
3. The round bus bar must be removed. Remove the M10 hardware
and slide the bar out.
4. Remove the screws from the three terminals to allow removal of
the ring lugs.
5. Remove the four screws on the base of the Hall Effect current
sensor.
6. Replace the Hall Effect current sensor. Note the arrow must be
oriented as shown in the illustration below.
7. Slide the bus bar back into place and secure with the M10 hardware.
8. Fasten the ring lugs on the wires back into place in the correct
position. Do not overtighten or you will break the threaded stud.
