5. Installation
5.3.1
Supporting floor
For a correct support of the electronic unit and to avoid the transmission of vibrations, it is necessary to build
a reinforced concrete platform (7) on the floor, isolated from the rest of the structure.
The generating set frame must be fixed to the platform (7) with dowels or anchor bolts.
The platform must have a length (D) and a width (E) greater than 400 mm (200 mm per side) with respect to
the support base of the generating set (200 mm per side).
The weight of the platform must be 3 times the static weight of the generating set reported in the technical
data.
The floor of the room must be level and adequate to support the weight of the generating set.
If the generating set is not equipped with a liquid containment tank, the door thresholds (9) or entrance to the
room must have a plinth that can contain the liquids in case of leakage.
5.3.2
Opening and ventilation of the room
The room must have a sufficient ventilation system to dispose of the heat produced by the generating set
during operation, without any possible stagnation or recycling of overheated air.
The inlet and outlet openings of the cooling and combustion air must be sized taking into account the mini-
mum air flow rates and maximum back pressures reported in the engine manual.
The air inlet opening (8) must be positioned near the floor towards the rear of the generating set.
If the air inlet (8) and outlet (6) openings are not aligned with the generating set, ducts must be installed to
convey the air and ensure ventilation of the room.
5.4 Grounding
*
Important
• Comply with local and/or current regulations on installation and electrical safety.
The grounding terminal (1) is in the position shown in figure.

5.4.3 Grounding with hearth leakage relay
Connection to a grounding system is mandatory for all models equipped with a hearth leakage relay.
In these groups, the star centre of the generating set is generally connected to the machine ground.
By adopting the TN or TT distribution system, the differential relay guarantees protection against indirect
contacts.
If powering complex systems that require or adopt additional electrical protection devices, coordination be-
tween the protections must be verified.
Use the grounding terminal (1) for connection.
