Precautions regarding accidental earth leaks
The charger's PE terminal must be earthed and
connected before any other terminal.
The shore-power unit must be closed before it is turned
on with the screw provided for this purpose.
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.
Accidental leakage current between the charge circuit
and the earth
Accidental current leakage at the earth must be
detected by means of an independent protective device
outside the shore-power unit (a residual current device
or an insulation detector).
The installer should decide on the rating and nature of
the protection according to the risks. Special precautions
should be taken on any installation prone to electrolyse
phenomena. Regulations require the presence of a
battery switch on the outputs of the + and the - poles.
Precautions regarding lightning
In areas highly exposed to lightning, it may be
advisable to install a lightning arrestor upstream of
the shore-power unit to safeguard it against
irreversible damage.
