Precautions regarding the electric shocks
Risk of electric shock and danger of death: it's strictly
forbidden to interfere in the isolation transformer when
under voltage.
Precautions regarding accidental earth leaks
The isolation transformer PE terminal must be earthed and
connected before any other terminal.
The isolation transformer must be closed before it is
switched on.
People protection
AC input supply: accidental leakage current between phase
and earth
Standard NFC15-100 should be followed when installing.
Use the services of an electrician or professional installer
to make the necessary connections. The isolation
transformer should be connected to a system having a
30mA differential two-poles circuit-breaker.
AC output distribution: accidental leakage current
between output circuit and the earth
Accidental current leakage at the earth must be detected
by means of an independent protective device outside the
isolation transformer (a residual current device or an
insulation detector).
The installer should decide on the rating and nature of the
