3.3.1.2 Preventing running water or spray falling on the charger
The protection factor is IP23 and the charger position must be chosen so as to prevent any
moisture or salt entering the charger.
If this were to occur, the equipment would be irreversibly damaged and there would be a
potential risk to the user.
You are recommended to position the charger in a dry, well-ventilated location, away from
any source of heat.
3.3.1.3 Arrangements for the batteries
Batteries connected to the charger are likely to give off explosive gases during the charging
phase.
You are therefore recommended:
to ban the use of any equipment generating sparks and flames near to the batteries.
to position the batteries in a well-aired and ventilated location.
to take note of the battery manufacturer's instructions when installing the batteries.
3.3.1.4 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.
3.3.1.5 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.
