Check Mains CT polarity on the bus bar
Current flow
After installing the MAINS CT and voltage connections, undertake a visual check using the steps below:
•
Check the Mains CT secondary wires (S1, S2) to ensure the correct polarity as shown in the schematic. This
implies, that the R phase CT should be connected to the R phase bus bar.
• Check Y and B phase CT location as well as their respective CT secondary wires to properly connect as per
the above schematic diagram.
iSAVER parameters check
After completing the iSAVER installation, based on the instruction input parameters into the IP Motherboard (as per
the provided data sheet), re-check the PT and CT polarities. The load on the iSAVER at this time should be at least
15%.
To verify the PT and CT connection on the IP Motherboard, proceed to the display page and check/ Records on the
commissioning data sheet the following parameters on the HMI screen.
