5.1.1 Connections to the Test Setup or AC Voltages
AC voltage or currents can be applied to the board for testing purposes at these points:
¥ L and N for voltage inputs. This can be up to 240 V ac 50/60 Hz.
¥ CUR1+ and CUR1- are the current inputs after the sensors. When CT or shunts are used, make sure that the voltages across CUR1+ and CUR1- do not exceed 500 mV.
¥ CUR2+ and CUR2- can also be used as current inputs after the sensors. When CT or shunts are used, make sure that the voltages across CUR2+ and CUR2- do not exceed 500 mV.
