*1: If input sampling period is set to 100 ms for 2 loops, only loops 1 and 2 are available.
*2: This value assumes that all input terminals are correctly wired (that is, solderless termination, wire diameters and
connections are correct).
*3: This value assumes that the power supply frequency is correctly selected.
*4: This module continues to operate at a input accuracy of ±0.5% max. of F.S. during the radiated electromagnetic field test.
