1.3.5 Risks related to electrical networks

The electrical equipment supplied with the generating set complies with standard NF C15.100 (France), or with the standards of
the countries in question.
The earth connection must be installed in accordance with the standards in force in each country in question, and with the
neutral system sold.
Read the manufacturer's identification plate carefully. The values for voltage, power, current and frequency are shown. Check
that these values match the supply use.
Never accidentally touch stripped cables or loose connections.
Never handle a generating set with wet hands or feet.
Maintain electrical wires and connections in good condition. Using equipment in poor condition can lead to electrocution and
damage to equipment.
Always disconnect the power to the equipment or facility (generating set voltage, battery voltage and network voltage) before
any operation.
The electrical connections must be made in accordance with current standards and regulations in the country of use.
Do not use faulty, poorly insulated or provisionally connected wires.
Never reverse the positive and negative terminals on batteries when connecting them. This could cause severe damage to the
electrical equipment. Follow the wiring diagram supplied by the manufacturer.
The generating set should not be connected to any other power sources, such as the mains supply network. In specific cases
where there is to be a connection to existing electrical networks, this must only be installed by a qualified electrician, who should
take the operating differences of the equipment into account, according to whether the mains supply network or generating set
is being used.
Protection against electric shocks is ensured by an assembly of specific equipment. If this needs to be replaced, it should be by
components with identical nominal values and specifications.
If the protective plates (blanking covers) need to be removed to route cables, the protector (blanking cover) must be refitted
when the operations are finished.
Due to high mechanical stresses, use only strong flexible wiring with rubber sheathing, compliant with IEC 245-4, or equivalent
wiring.

1.3.6 Dangers presented by electric currents (first aid)

First aid
In the event of an electric shock, shut off the power immediately and activate the
emergency stop on the generating set or lighting column. If the voltage has not yet
been cut off, move the victim out of contact with the live conductor as quickly as
possible. Avoid direct contact both with the live conductor and the victim's body. Use
a dry plank of wood, dry clothes or other non-conductive materials to move the victim
away. The live wire may be cut with an axe. Take great care to avoid the electric arc
that will be generated by this.
Begin emergency procedures
Resuscitation
If breathing has stopped, begin artificial respiration at once in the same place the accident took place unless the victim or operator's
life could be endangered by this.
In the event of cardiac arrest, carry out cardiac massage.

1.3.7 Risks related to moving the set

To unload the generating sets, pump units or lighting columns from their transport support brackets under optimum safety and
efficiency conditions, you must ensure that the following points are observed:
The lifting machinery or equipment is suited to the work required, in good condition and with sufficient lifting capacity.
The slings are positioned in the rings provided for this operation, the forklift arms are resting fully underneath all of the base
frame cross-beams, or the lifting bars are inserted in the apertures provided for this purpose in the base to lift the entire
generating set (according to models).
For completely safe working conditions and to prevent damage to the components fitted on the upper edge of the set, pump unit
or lighting column, the generating set, pump unit or lighting column must be lifted up with an adjustable boom. All the chains and
cables must be parallel with each other, and as perpendicular as possible with the upper edge of the generating set, pump unit
or lighting column.
If other equipment fitted on the generating set, pump unit or lighting column alters its centre of gravity, special lifting devices
may be necessary to maintain correct balance and completely safe working conditions.
The ground must be able to withstand the load of the generating set, pump unit or lighting column and its lifting machinery
without stress (otherwise, put down beams of sufficient strength in a stable configuration).
Position the generating set, pump unit or lighting column as close as possible to its place of use or transport, in a clear space
with free access.
Never perform work on a generating set, pump unit or lighting tower just hanging from a lifting device.
