During the installation of the power meter, no additional
protective devices are required. The meter connection
terminals must be directly connected to the L (line) and N
(neutral) wires. The split core CT is installed on the L phase
in the same direction as the current (see Figure 25). After the
CT is wired to the S1 and S2 terminals of the power meter,
it is supplied directly by L (phase) and N (neutral) that are
respectively wired to the terminal 3 and 4 of the power meter
itself as it is displayed in the Figure 25.
