5.2.9 Connection of the protective earth
As this is an equipment with class I protection against electrical shocks, it is essential to
install the protection earth conductor (connect
earth). Connect this conductor, before
supplying voltage to the input terminals.
Make sure that all the loads connected to the stabilizer, the protective earth is only connected to
this point. The fact of not respecting the protective earth connection of the load or loads to this
single point, will create back feed loops to earth that will affect to the quality of the power supplied.
Regardless of the equipment has one or two protection earth terminals, are always joined to the
ground of the stabilizer.
In three phase stabilizers consisting of single phase equipment’s, it is needed and essential to make
one of these two options as regards to the earth :
•
Joint the earth terminals (screws) of the three equipment’s by means of the cable
and connect the protective earth cable coming from the installation to any of the
terminals
•
Or come with one separate earth cable to each terminal (screw) of each
equipment, but they have to come from the same point.
