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 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 sensor. For quick reference, look for the white arrow
when checking the orientation of the Hall Effect 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 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
