Illustration 21: Power meter components
• Never confuse inputs A1 and A2!
• The lines connected to the voltage
measurement terminal strip (3) must be
protected by suitable miniature circuit
breakers. Additional miniature circuit
breakers do not have to be installed if
the lines are already protected in ac-
cordance to the relevant, currently ap-
plicable regulations and standards.

Illustration 22: Connection to the voltage ter-
minal strip at single-phase (1~) and three-
phase (3~) mains
• 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.
