2.8.2
Fixed installation or mains failure
When supplying a fixed installation (e.g. as backup for mains outages), the unit must be connected by a qualified electrician in
accordance with the regulations applicable at the installation site. The units are not designed to be connected directly to an
installation (risk of electrocution or damage to equipment).
A - If the unit is not equipped with an integrated differential protection device at delivery (standard version with insulated neutral on
the unit's earth terminal):
- Use a source inverter.
- The unit does not need to be earthed.
B - If the unit is equipped with an integrated differential protection device at delivery (standard version with alternating neutral
connected to the unit's earth terminal - for use with TT or TN systems):
- Use a source inverter.
- Connect the unit to the earth: attach a 10 mm2 copper wire to the unit's earth terminal (A1) and to a galvanised steel
earthing rod set 1 metre into the ground.
2.8.3
Mobile application
The units are intended to operate while stationary. They may not be installed on a vehicle or other mobile equipment unless a study
has been carried out analysing the unit's various installation and usage specifications. It is prohibited to use the unit whilst it is in
motion. If earthing is not possible, connect the unit's earth terminal (A1) to the vehicle earth.
2.8.4
Connection and choice of cables
For all connections, use flexible, strong rubber-sheathed cables which comply with standard IEC 60245-4 or equivalent cables, and ensure
that these are kept in perfect condition. Only use one item of class I electrical equipment per socket and connect up equipment using a
cable equipped with a PE protective conductor (green/yellow); this protective conductor is not required for class II equipment. Adhere to
the cross sections and lengths recommended in this table during installation or when using electrical extensions.

Risk of hearing loss
DANGER
Refer to the "Technical specifications" paragraph for the sound pressure level at 1 m.
If the unit must be installed indoors: ensure that the sound level of the enclosure in the room is significantly reduced (then check
this by subsequently measuring the sound pressure level), ventilate the room, evacuate all exhaust gases and install a carbon
monoxide detector in the room.
