3.2.5 CURRENT TRANSFORMERS
WARNING!: Do not disconnect this plug when the CTs are carrying current.
Disconnection open circuits the secondary of the C.T.’s and dangerous voltages may then
develop. Always ensure the CTs are not carrying current and the CTs are short circuit
connected before making or breaking connections to the module.
NOTE: The module has a burden of 0.25 VA on the CT. Ensure the CT is rated for the
burden of the controller, the cable length being used and any other equipment sharing the CT.
If in doubt, consult with the CT supplier.
NOTE: Take care to ensure correct polarity of the CT primary as shown below. If in doubt,
consult with the CT supplier.
