Lighting Class I
At a work or construction site where there is no fixed connection (e.g. distribution box), Class I lamps may only be used in a permanent installation, mounted above 2,5 metres (out of reach) e.g. on a wall or tripod. The lamps must be connected to the mains by means of a 3-core connection cable that is earthed. Examples: TAB45050, TAB45150, TAB45072G.
Lighting Class II
Class II lighting, such as TAB82850 and TAB20515, is for use within arm’s reach on the work floor (portable, mobile luminaires). These work lights or construction lights have a 2-core connection cable type H07RN-F with a minimum length of 5 metres which must be connected to the mains. Class II lamps must always be double insulated.
Floor stands or extendable tripods (such as TAB32501) for mobile construction lamps must have insulated handles and must not fall over on a 15° slope.
Lighting Class III
This lighting is suitable for use on the work floor but also in narrow, conductive spaces (cellars, boilers, etc.). Class III lights must be connected to safety transformers with an output voltage of less than 50V. The safety transformer must be placed above the floor and outside the room. If power tools are used, an isolation transformer must be used. This combined transformer makes it possible to use 230V power tools in combination with 42V safety lighting.
