Calibration
The voltage and the current terminals simply unplug to facilitate field calibration. A portable meter tester can easily plug into the removed terminals.
Also, there are two rows of CT terminals used when paralleling two sets of CTs. Remember Current Sensors with voltage outputs cannot be paralleled. Voltage is not additive, where current is.

There is a RS485 ModBus RTU terminal next to the relay. This port works
with the Communication Gateway/Intelligent
