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 0.5VA 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 your CT supplier.
