• Do not confuse the phases.
Power measurement only works if the
current and voltage of the same
phase are measured.
Example: clamp-on current
transformer L1 (marked with number
1) must be connected to phase L1.
This phase L1 must also be connected
to terminal L1 of the voltage
measurement terminal strip. Only
then can the correct power for phase
L1 be determined.
