CT-100/CT-150 Series User’s Manual Installation and Operation 150) is fed to pin #6 in “C”-option and to pin #6 in the “P”-option. Current return pins are respectively found on pin #1 and on pin #7 in the “C”- and the “P”-option. Maximum secondary current is rated at ±100 mA and an external shunt resistor, which can be placed close to the user’s desired measuring circuit, is needed in order to convert the current signal to voltage. -
