electric shocks when touched
operating faults in the luminaires
reduced service life for lamps and luminaires
fire hazard in the luminaire or its surroundings
Conformance with the standard is indicated by the appropriate markings (VDE, SEV,ÖVE, KEMA).
The protection class indicates to what extent the luminaire offers protection against electric shock (short circuit). The protection class may be indicated with Roman numerals or with the help of pictograms. The following classification is in use :
- Basic insulation and protective earthing for all exposed live parts. Most luminaires are designed to be connected to a protective earth conductor (unless otherwise indicated).
Basic insulation and additional protective insulation, no protective earthing.
- Operation on and with Protective and Extra-low Voltages (max. 50V) e.g. spots for low-voltage trunking.
