Connecting the power meter
The following points must be observed when connecting power meter:
The voltage reference terminal must be protected by a suitable
circuit breaker. A 6A MCB is recommended.
Connect the CTs for production into A1
terminal and CTs for consumption into A2
terminal on top left of the power meter.
When wiring the voltage terminal strip, pay
attention to the correct sequence of the
phases as shown in the figure on the left. The
connection to the voltage terminal strip
depends on the number of phases. In the case
of a single-phase (1~) mains, the voltage
terminal strip must be wired like it is shown on
the bottom part of the figure on the left. In
case of a three-phase (3~) mains wire as
shown on the top part of the figure.
