SAFETY WARNINGS
To guarantee correct installation, proceed as follows:
1) The appliance should be installed by a competent operator
2) The appliance should be installed in a panel in such a way as to
guarantee that the terminals are inaccessible after fitting
3) A protection device against over-currents should be installed in the
electrical system, upstream of the energy meter
4) Connect the instrument as shown in the alongside diagrams
5) Before touching the connector terminals make sure that the wires to
be connected or already connected to the instrument are not live
6) Touch the dip-switches only when the instrument is not powered
7) Do not power or connect the instrument if any part of it is damaged
