High Voltage and Current – This component can operate at high voltages and currents, posing a risk of electric shock. Pay attention to the maximum voltage and current values, as well as appropriate markings indicating these limits.
Caution During Installation – Ensure that the components are correctly mounted in the circuit, as improper connections can lead to overheating, damage, or fire.
Hot Components – Electronic components may heat up during operation, so it is important to follow the recommendations regarding the maximum operating temperature. Appropriate heat sinks or cooling systems should be used to ensure effective heat dissipation. Caution should also be exercised to avoid burns.
Swallowing Hazard – Small fastening components, such as screws, nuts, or washers, can pose a choking or swallowing hazard, especially for children. They should be stored in a place out of reach of children.
Spreading of Small Components – These components can pose a tripping or loss hazard during work. They should be stored in containers that prevent spillage.
