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 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 load cable must be disassembled to allow removal of the Hall
Effect sensor. Remove the hardware to allow the cable to slide out.
4. Remove the plug connecting the sensing wire to the Hall Effect sensor.
5. Remove the four screws on the base of the Hall Effect sensor, and
remove the Hall Effect sensor.
6. Replace the Hall Effect sensor. Note the arrow must be oriented as
shown in the illustration below.
7. Slide the load cable back into place and secure the hardware.
8.
Plug the connector back into the sensor. The plug is keyed so that it
cannot be plugged in incorrectly.
