7.4.1 Power Measurement on a Machine
For measuring power, all of the eight CAGE CLAMPS
®
have to be connected
according to the figure below.
Do not confuse current and voltage clamps!
When making the connections do not confuse the current and voltage paths, as
connecting the phase voltages directly to the low impedance current clamps IL1
… IL3 shall destroy the I/O module!

Negative power values!
If you measure negative power values, check the connection of the associated
current transformer circuit in the proper direction.
