SAFETY WARNINGS

To guarantee correct installation, observe the following instructions:

1) The appliance must be installed by a qualiﬁed operator

2) The appliance must be installed in an electrical panel which, after installation,

leaves terminals inaccessible

3) A protection device against over-currents must be installed in the electrical system

upstream of the energy meter

4) Connect the instruments as shown in the diagrams opposite

5) Before making contact with terminals, ensure that conductors to be connected to

the appliance are not live

6) Do not power or connect the appliance if any part of it is damaged
