Table with procedure steps for insulation measurement referred to the
installation reported in Errore. L'origine riferimento non è stata trovata.
Note
The switches D and E are those installed near the load having the purpose of
separating it from the installation. In case the above said RCDs do not exist it is
necessary to disconnect the users from the before making the insulation resistance
test.
ATTENTION:
If the installation includes electronic devices, disconnect them from the installation and
in case this is impossible only the test "a" is to be effected, that is to say between
active conductors (which in this case SHALL be connected together) and the earth.
