Manual
Version 1.2.0
7.3.3 Additional Measuring Instruments in the Current Path
Please note that adding measuring instruments (such as ammeters) in the current
path can substantially increase the total apparent power.
In addition, the CAGE CLAMP

IN of the I/O module must form a star point
(neutral) for the three secondary windings. See figure above. Therefore, additional
measuring instruments must be potential-free and wired accordingly.
