3.4.1.4 Accidental leakage currents to earth
Accidental leakage current between line and earth
Comply with standard NFC 15-100 in respect of precautions over
installation. Have the connection work done by an electrician or
professional installer.
The charger must be connected to a system having a two-pole differential
circuit breaker with 30 mA sensitivity.
Accidental leakage current between charge circuit and earth
Detection of accidental leakage currents to earth must be provided by a
safety device outside the charger (residual differential current device or
insulation monitor device).
The installer must ensure that the rating and nature of the protection are
appropriate for the risks.
Special precautions are recommended on any installation where there is a
danger of electrolytic effects.
Regulations require the presence of a battery cut-out on the output + pole
and on the output - pole.
3.4.1.5 Precautions regarding lightning strike
In geographic zones exposed to a high risk of lightning strikes, it may be
worthwhile fitting a lightning conductor on the inlet side of the charger in order
to prevent the latter being irreversibly damaged.
3.4.1.6 Electromagnetic interference generated by the charger
Use screened cable for all connections (*). The screening at both the emitter
end and receiver end must be connected to earth..
Make sure the length of the cables and screening connections are kept as
short as possible.
Route the cables as close to earthed objects as possible ("flying" cables or
cable loops are to be avoided – fasten the cables against earthed objects).
Separate the power supply cables from output cables.
Separate power cables from monitor signal cables (minimum 200 mm).
Cables must carry only the charger power supply. Branch or bridging
connections in order to supply another equipment are to be banned.
(*) This is advice for installation and not an obligation. The electrician installer
will decide whether to use screened cable or not, based on the EMC
environment.
