In the case of a fire or short circuit, no insurance will cover the damage because the component was used for a purpose different from what the
manufacturer intended (misuse). It doesn’t matter if it still works or if others use it. No insurance will cover the damage, whether it’s a fire or something else.
Therefore, a CE-marked sign with an LPV power supply would constitute criminal offenses under the Italian Penal Code, specifically:
● Art. 441 “Adulteration of things harmful to public health”: Because there is no galvanic separation between the primary and secondary, making it
dangerous.
● Art. 515 “Fraud in commerce”: Because it is not suitable for signs, as stated in the instruction manual.
● Art. 517 “Sale of goods with false markings”: The sign is CE-marked without meeting the required standards, as it contains a power supply that is not
suitable for the lighting/signage sector and does not comply with EMC Directive standards.
Yes, since DM 37/08 (2008), a project is always required for electrical systems in buildings, regardless of their use. In some cases, the technical director of the installing
company can sign it, but for certain conditions, it must be prepared by a registered professional.
When is a professional’s project required?
● Residential buildings with power over 6 kW or area over 400 m².
● Commercial/industrial buildings with power over 6 kW, area over 200 m², or systems exceeding 1000V.
● Specific areas like medical rooms or high fire-risk zones.
Other systems:
● Electronic systems must be designed if they are part of a system that requires a project.
● Fire detection systems must be designed if they are in activities requiring a fire prevention certificate.
According to Article 10 (Penalties):
1. Municipalities are responsible for imposing penalties based on the severity of violations:
○ €1,000 to €5,000 for incomplete or missing data on public outdoor lighting installations, if operators fail to comply with regulations.
○ €2,000 to €6,000 for partial or delayed implementation of required adjustments. The penalty doubles if the violation occurs in areas with specific
protection against light pollution.
○ €2,000 to €6,000 for failure to comply with regulations related to the design, installation, or management of installations, with penalties doubled
in areas with special protection against light pollution.
