DANGER
RISK OF ELECTROCUTION
DANGER OF DEATH
Units supply electrical current while operating; comply with the applicable legislation as well as the
installation and usage recommendations given in this manual. If you are in any doubt regarding
installation, please contact your nearest agent.
Do not connect the unit directly to other power sources (such as the mains for example); fit a source
changeover panel.
Never touch stripped cables or disconnected connectors. Never handle a unit with wet hands or feet.
Never expose the equipment to liquid splashes or rainfall, and do not place it on wet ground.
2.10.1 Temporary or Semi-temporary Installation (Work site, Show, Fairground, etc.)
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 differential device calibrated to 30mA at the output of each of the unit's sockets (place each device at least 1 meter from
the unit, protecting it from weather conditions).
- If one or more mobile or portable devices are used occasionally, 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):
- Connect the unit to the earth: attach a 10 mm
2
copper wire to the unit's earth terminal (A1) and to a galvanized steel earthing
rod set 1 meter into the ground.
2.10.2 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 mm
2
copper wire to the unit's earth terminal (A1) and to a galvanized steel earthing
rod set 1 meter into the ground.
2.10.3 Ground
Terminal
Ground terminal (A1) connects earth line for prevention of electric shock. When electric device is grounded, be sure to ground
generator also.
Connect generator to ground: Attach a 6 AWG (10 mm
2
) copper wire to generator’s ground connection and to a galvanized steel
grounding rod (not provided) driven 3.3 ft. (1 m) into ground.
2.10.4 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.
2.10.5 Cable
Selection
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.
