Replacement
1. Ensure there is no power to the equipment.
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.
3. Disconnect the wires.
4. The bus bar must be disassembled to allow removal of the CT. Remove the
M10 hardware to allow the bus bar to slide out.
5. Remove the four screws located in the base of the CT and remove.
6. Replace the CT, ensuring the proper orientation. Fasten the CT securely
with the four screws in the base.

Sensors
Arrows on Hall Effect sensors indicate direction of current flow.
Customer Terminals shown for bottom cable entry. Customer must
remove and re-orient terminals if top entry is required.
ATTENTION: 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.
The CT and wires must be in the proper orientation. Note the position
before disassembly.
