1. Because of input voltage level of the device, when using an external PT, the primary voltage is the product of the PT ratio.
Note
If voltage input is out of the measurement range, the accuracy may be affected. For voltages greater than the
voltage input specification, an external PT[Potential Transformer] should be used.
Warning
When an external PT is used, a fuse should be mounted on the secondary side.
