Test terminal block status before installing the meter (terminal layout
according to DIN)
The electrical connections to the meter should be made as follows accord-
ing to the connection diagram:
1. Check whether the preliminary work described above has been per-
formed. If not, complete this work (test terminal blocks should only be
touched with an insulated screwdriver).
2. Check with a phase tester or universal measuring instrument whether
the connecting wires are live. If so, remove the corresponding supply
fuses and keep them in a safe place until installation is completed, so
that they cannot be replaced by anyone unnoticed.
Connecting the phase connection lines
1.
Shorten the phase connecting wires to the required length and then
strip them.
2.
Insert the phase connecting wires in the relevant terminals (the termi-
nals are numbered as shown in the connection diagram) and tighten
the terminal screws firmly (torque 1.7 Nm).
It is recommended to identify the beginning and end of the relevant
conductors with a suitable test unit (e.g. buzzer) to ensure that the
right consumer is connected to the meter output.
