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 current transformer. 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 CT. For quick
reference when checking the orientation of the CT, look for the white dot.
I M P O R T A N T I M P O R T A N T The CT and wires must be in the proper
