Connection to current and voltage terminals
Proceed as follows when connecting the LZQJ-SGM:
1. Ensure that all lines are free from voltage.
2. Shorten the conductors to the necessary length if necessary.
3.
Strip each of the conductors to the stripping length specified
in the table below (for transformer connected meters, see
page 15; for direct connected meters, see page 19).
4.
In case of finely stranded conductors, equip each wire with
a ferrule.
5. Open the screw-type terminal.
6. Insert the conductor into the screw-type terminal up to its
insulation.
7. Tighten the screw of the screw-type terminal while observing
the maximum torque as specified in the above table. Ensure that
the cable insulation is not put inside the terminal.
8. Repeat the process until all conductors are connected.
