The scope of protective measures against electrical shock describes three classes of protection: Protection class I: Luminaires for connection to the mains side protective earth. The icon is located at the junction. Protection class II: Luminaires with an additional or reinforced insulation. They do not have a protective earth terminal. Protection class III: Luminaires for operation with protective extra low voltage (PELV).
