5. GENERAL DANGER INFORMATION
5.1 RISK OF ELECTROCUTION
The machine can produce dangerous electrical voltages and cause deadly electric shocks.
Connecting to the power grid also involves dangerous tensions.
Avoid contact with exposed wires, terminals, connections while the unit is running. Make sure that
all the covers and barriers you have prepared are up and running and in place before using the
machine. If it is needed to work on a machine while it is activated, stand on an isolated dry surface
to reduce the risk of electric shocks
DO NOT handle any type of electrical device while standing on water, while barefoot or while your
hands and/or feet are wet, this could cause DANGEROUS electric shocks.
In the event of an accident caused by electric shock, immediately turn off the electricity source.
If this is not possible, try to free the victim from the active conductor. Avoid direct contact with the
victim. Use non-conducting material (e.g. wood) to free the victim from the active conductor. If the
victim is unconscious, apply first aid procedures and call medical assistance immediately.
5.2 RISK OF BURN
Avoid contact with the floodlights when operating lighting towers.
Use appropriate Personal Protective Equipment (PPE) when operating the machine.
5.3 RISK OF ENTANGLING
Do not remove protections placed on rotating parts, air intakes and belts.
Do not clean or perform any maintenance on moving parts.
Use appropriate Personal Protective Equipment PPE when operating the machine.
5.4 FIRE-FIGHTING INFORMATION
In case of fire it is recommended to use a powder extinguisher with fire class 13A 89B C.
5.5 FOR MACHINES EQUIPPED WITH COMBUSTION ENGINE
5.5.1 RISK OF FIRE OR EXPLOSION DURING REFUELING
Always turn off the machine before refueling.
Do not smoke during refueling.
The refueling operation must be carried out in order not to spill fuel from the tank.
In the event of a fuel leak, dry and clean the parts.
Verify that there are no fuel leaks and that the pipes are intact.
5.5.2 RISK OF BURN
Avoid contact with hot surfaces, such as mufflers and their extensions or the engine body when it
is running.
Use appropriate Personal Protective Equipment (PPE) when operating the machine.
5.5.3 NOISE
Use proper Personal Protective Equipment (PPE) for acoustic protection.

6. DISPOSAL OF WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT
Professional disposal of this machine avoids negative effects on human health and the
environment, helps with the targeted treatment of pollutants and makes it possible to recycle
valuable raw materials.
FOR CUSTOMERS IN EU COUNTRIES
This machine is subject to the European directive for old electrical and electronic equipment
(Waste Electrical and Electronic Equipment WEEE), as well as the corresponding national laws.
The WEEE directive provides the framework for an EU-wide treatment of old electrical equipment.
The machine is marked with the following symbol of a crossed-out garbage bin. This means that
the machine can not be disposed in normal household waste but that it must be disposed of in a
separate, environmentally friendly collection facility.
This unit is provided as a professional electrical tool exclusively for commercial use (a so-called
B2B device according to theWEEE directive). Unlike equipment mostly used in private households
(so-called B2C devices), this machine may therefore not be disposed of in some EU countries at
the collection points of public waste management organizations(e.g. municipal collection stations).
If there are any doubts, information regarding the different methods of disposal for B2B electronic
devices for each country can be obtained from the sales location, so that the disposal takes place
in accordance with the valid statutory provisions. There are also some notes to follow in the sales
contract or in the general Terms and Conditions of the sales location.
FOR CUSTOMERS IN OTHER COUNTRIES
It is recommended that you do not dispose of the machine in normal household waste but rather
in a separate, environmentally friendly collection facility. National laws also may, under certain
circumstances, prescribe the separate disposal of electrical and electronic products. Correct
disposal of this machine in accordance with current national guidelines must be assured.

or unhooked.
11.2 POSITIONING
It is recommended to place the machine on a stable place, checking the consistency of the
soil to provide safe support to the stabilizers.
Pull the hand brake if the tower is provided with trailer for fast towing.
Choose an open and ventilated location to ensure exhaust gases are released away from the work
area.
Verify that there is complete air replacement and that the hot air is expelledand does not recirculate
in the generator set in order to avoid dangerous temperature rise.

11.3 PRELIMINARY CHECKS
At the moment of purchase the machine is provided with engine oil and coolant in the radiator (if
present).
Before every next use, check the relevant levels.
Check that the switches on the RCD/MCB device are all in "OFF" position.
Make sure that no load is connected to the single-phase auxiliary socket .
Make sure the emergency stop button
STOP
is re-armed. If not, turn the button clockwise.
11.4 EARTHING
If necessary, connect the machine to ground using the MET (main earth terminal) .
The ground conductor must have a section of no less than 6 mm2.
The manufacturer is not responsible for any damage caused by failing to connect the
machine to ground.
Prescriptions and requirements to be fulfilled are as follows.
11.4.1 EARTHING REQUIREMENTS
Grounding must be carried out in accordance with the regulations at the site where the unit is
operated. It is the responsibility of the user to determine the requirements and/or applicability of
the local legislation concerning ground installations.
Grounding must be supervised or carried out by skilled and experienced personnel in accordance
with local regulations.
Grounding must be of robust construction and maintained intact to ensure its proper functionality
and the health and safety of personnel and surrounding environment.
The unit is provided with additional protection via a differential switch (RCD); one of the two poles
of the single-phase generator, together with the metal parts that make up the machine, are
connected to the main earth terminal (MET).
Requirement in compliance with BS 7430.2011 regulations:
Grounding in the UK must be carried out according to the requirements of the BS 7430:2011
standard. The machine should be connected to earth whenever possible, even if it is not mandatory
for generators with nominal power under 10kW.
The manufacturer recommends to connect the MET (main earth terminal) on the machine to true
earth through the grounding conductor.
Examples of ground connection. The following are examples of acceptable methods:
(1) an earthing rod pushed to a suitable depth;
(2) the earth terminal of an adjacent fixed installation;
(3) permanent structural metalwork;
(4) exposed reinforcement bars in foundations or concrete structures;
(5) a suitable metal structure that is certain to be grounded.

V20 V20 PRO iQ20

TL228-01-00-02
06/02/2023
English
The ground conductor must have a section of no less than 6 mm2.
The resistance of such conductor must not be greater than 0.2Ohm, including contactresistances.
An instructed/informed person should regularly verify the condition of the grounding conductor.
Damage and/or disruption of the grounding conductor could lead to danger.
11.4.2 NOTES
As required by the IEC 60364, HD 60364, the ground conductor has been sized (like the protective
conductors) as shown by the table below.
Residual current devices (RCDs) can be used for 2 purposes on the unit, namely:
(1) to monitor the insulation of the system that has a metal structure containing the (isolated)
conductors of the circuit;
(2) to protect people in the event of contact between an active conductor and earth or a metal
structure.
Point (2) above requires the electrical system to be referenced to earth to allow an RCD to operate
properly on the first fault to the true ground.
Ground resistance, if possible, should not exceed 200 Ohm to ensure a cautionary margin.
Earthing rods with the highest practicable depth should be preferred to ensure the highest
installation safety.
For example, the resistance of an earthing rod can be calculated with the following formula:
Where:
ρ is the resistivity of the ground, in ohm meters (Ωm);
L is the length of the electrode, in meters (m);
d is the diameter of the rod, in meters (m).
When ground resistivity is not measurable, refer to the following table.
