Wiring System Combination
• If you select 1P3W, 3P3W, 3P4W, 3P3W(3V3A), or 3P3W(3V3AR) for the wiring system, the wiring unit
is set with the two or three input elements adjacent to the selected element whose element numbers are
larger than the selected element.
• On models that have six or more input elements installed, up to three wiring units (ΣA, ΣB, and ΣC) are
automatically set. The wiring unit symbols ΣA, ΣB, and ΣC are attached to the element numbers in order,
starting with the smallest number.
Note
• You cannot set the wiring units for larger element numbers before the wiring units for smaller element
numbers.
• You cannot assign different types of input element to a wiring unit.
• For the 760903 current sensor input element, when Range Σ Link is set to ON, the wiring unit cannot be
set among elements whose CT Type or Input Resistance setting is different.

elements can be set independently even when they are assigned to the same wiring unit.
• For the 760903 current sensor input element, when any of the wiring units is set among the elements
whose CT Type or Input Resistance setting is different, Range Σ Link cannot be set to ON.
