CHECKING MAINS POLARITY

To check the proper electrical polarity of live and neutral wires,
proceed as follows:
(1) Connect an AC voltmeter between the live terminal of mains
connection points and the protective ground screw.
(2) Turn on the room supply and check that the full line voltage
is measured: if not, reverse the mains connection points
and repeat.
(3) Also check that in the same conditions no voltage is present
between the neutral terminal of the mains connection points
and the protective ground screw.
(4) Mount the cover (a) on the column.
