3.3.1.6 Electromagnetic interference generated by the charger
By virtue of European directive 89/336/EC, the equipment must conform to
electromagnetic compatibility criteria
The two main demands in terms of electromagnetic compatibility are:
Emission: Protection of the environment against disturbance by conduction and
radiation.
Immunity: Absence of susceptibility in a disturbing atmosphere.
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.
The coils of contactors, relays, solenoid valves and electromagnets must be equipped
with overvoltage arresters (RC circuits, varistor or diode on direct current, RC circuits
or varistor on alternating current).
Additional filters may be mounted according to applicable standards. Disturbance
attenuation enables the specified levels to be attained. The filters must be mounted as
near as possible to the appliance.
Remember that filters increase the leakage current.
As a general rule, we recommend consulting the manufacturer before installing a filter,
particularly on the load and control cable side.
(*) 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.
3.4 Special recomandations for installation
This section lists the operations to be performed in order to commission the charger. It is
advisable to comply strictly with these instructions before switching on for the first time.

3.4.1.Supply voltage

Check if the alimentation voltage is compatible with the tolerance of the product.
