EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60598-2-14 testing. IEC EN 60598-2-14 applies to cold-cathode tubular discharge lamps and similar equipment fixtures operating at a rated no-load output voltage of more than 1000 V but not more than 10000 V, and is mainly used for general lighting, indoor or lighting .
This standard does not cover luminaires with discharge tube luminaires and luminaires to be installed, operating with rated voltages not exceeding 60598 V (preheated cathodes) referred to relevant part 2 of IEC EN 1000.
In case of accidental contact between the high voltage circuit and the ground, the device will cut off the main supply of the luminaire or otherwise cut the output power. If only one pole of the supply voltage is switched, this switching must be connected to the phase of the supply.
Fault condition detection (earth leakage) must be made by means of suitable sensors connected to the output circuit, which will actuate the means arranged to interrupt the supply circuit or to cut the output power. The earth leakage protective device should be tested in accordance with the manufacturer's instructions for such devices. These tests should ensure that the units operate correctly.
If the protective device is designed to cut off the mains supply in the event of an earth leakage, the relevant means must be equipped with mechanical contacts. The use of switching via semiconductors (thyristors, triacs, etc.) is not allowed. If the circuit includes a flasher, any protection switch and reset circuit must be installed on the mains supply side of the flasher.
Detection of the abnormal condition should be made by the appropriate sensor connected to the output circuit (or other similar device) that will operate the protective switch to disconnect the supply circuit or cut off the output power.
The open circuit protection circuit should be tested according to the manufacturer's instructions for such devices. Such tests should ensure that the units function correctly and are installed correctly.
