28142 Rev 15 PROCESS DESCRIPTION
Current Shunt: A shunt located in the CP Interface enclosure is used to measure the current
to the terminal block. The voltage drop across the shunt is proportional to the current flowing
through it. The current shunt rating corresponds to the ampere scale on the meter.
Terminal Block: Customer terminal block, is a heavy-duty terminal block that will accept
customer anode & cathode wire up to 9 mm dia. (00 AWG).
Variable Resistor: A 300 W variable 0 to 1 ohms resistor located inside the enclosure may
be used to adjust the output power of the CP interface. This resistor may be wired in series
or parallel with the customers CP load depending on the application but comes factory-
configured with the resistor in series.
