5.2 Descriptions of Wiring
This chapter illustrates how wiring is done for this panel.
■
Measured Voltage:
When measured voltage is higher than the rated specication (refer to Electrical Specication) for the
device, use of an external potential transformer should be considered.
■
Measured Current:
When measured current is higher than the rated specication (refer to Electrical Specication) for the
device, use of an external current transformer should be considered.
