5.2.7 Connection of input terminals
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.
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
terminal.
Or come with one separate earth cable to each terminal (screw) of each
equipment, but they have to come from the same point
Depending on the model of stabilizer, the power supply connections are directly done to the
terminals or to the own rods of the input switch or breaker.
