Only used when the connection type is other than 3U.3C.
(10)
Indicates the relationship between the assigned voltage and the current direction.
Example: If you see Current 1 = 1, Current 2 = 5 and Current 3 = 3, this means that:
Current 1 is assigned to voltage 1 in the direct direction, current 2 is assigned to voltage 2 in the reverse
direction and current 3 is assigned to voltage 3 in the direct direction.
