AEE MARKA DE CONFORMIDAD A NORMAS UNE 12.4 GENERAL INFORMATION, OPTIC SPECIFICATIONS, INDEX As European norms are taken over in the national norms and published as such, all electrical equipment available in Europe should comply with these norms.The European testing institutes introduced the ENEC logo in January 1993. All luminaires supplied by Philips Lighting comply with the most recent European directives as indicated by the ENEC and CE marking on the product and packaging. 01 AENOR - Spain IMQ - Italy 03 05 KEMA - The Netherlands SEE - Luxemburg 07 ELOT - Greece ÖVE - Austria SEV - Switserland DEMKO - Danmark NEMKO - Norway EZU - Czeck Republic CEBEC - Belgium 02 04 IPQ - Portugal 06 NSAI - Ireland UTE - France 08 VDE - Germany BSI - United Kingdom SEMKO - Sweden FIMKO - Finland MEEi - Hungary SIQ - Slovenia
L942D943_SRC.QXD 11-03-2004 08:14 Pagina 12.5 Electrical supply An important step to harmonise the European market is the definition of a uniform electrical voltage. From 2003 onwards the voltage is 230 V/400 V with a tolerance of 10%. Philips Lighting indoor luminaires are designed for the future and will operate well on the supply of today and tomorrow.An example is electronic ballasts designed for a rated mains voltage of 220-240 V, with tolerance for safety of +/- 10% and tolerances for performance of –8% and +6% covering the full range between 202 V and 254 V. Ambient temperature Philips indoor luminaires are designed to meet the (environmental) conditions under which they are most likely to be used. The maximum ambient temperature Ta under which a luminaire can be safely applied, is indicated on the label on the products; if no indication is given the product is meant for a maximum ambient temperature of 25°C.The ambient temperature always refers to the typical use of the luminaire: indoors or outdoors.The majority of luminaires developed for office, shop and general indoor applications show no T a , thus meaning 25°C. Luminaires designed for industrial high-bay applications are designed for ambient temperatures as high as 40 to 45°C.The use of luminaires above their specified maximum ambient temperature may reduce safety margins and will in any case lead to a reduction of the lifetime of the various components; especially electronic equipment (ballasts and controls) is sensitive to overheating and lifetime will be reduced.Although using luminaires at (extremely) low temperatures does not normally affect safety, the operating (especially starting) of the lamp may be influenced. Fluorescent lamps should not be used below –5°C to –10°C, whereas high-intensity discharge lamps function well below –20°C. Upon request special solutions are often possible for higher or lower ambient temperatures. Electrical safety (classes) Electrical equipment is classified according to protection against electrical shock. In normal operation as well as during service and maintenance, luminaires should be protected against electrical shock. The safety of a luminaire depends on electrical, mechanical and thermal aspects; both under normal and fault conditions. The electrical safety classification drawn up by the IEC embraces four luminaire classes: Class 0, I, II and III. Class 0 luminaires are not available from Philips Lighting. Class III is only applicable to Safety Extra-Low Voltage luminaires (SELV).The table gives a brief description of each electrical safety class.The official definitions are too long to be reproduced in full here, but can be summarised as printed below. If a proper earth connection is available, Class I luminaires are applied. However, when no earth connection, or only a poor-quality earth connection is available, or where eddy currents are present, Class II luminaires shall be applied. Class II waterprotected luminaires are applied in (semi-)outdoor locations. Local electricity boards can provide the appropriate advice. Class I - symbol Luminaires in this class, besides being electrically insulated, are also provided with an earthing point (labelled) connecting all those exposed metal parts that could conceivably become live in the presence of a fault condition. Where the luminaire is provided with a flexible power lead, this must include an earth wire.Where this is not the case, the degree of electrical protection afforded by the luminaire is the same as that afforded by Class 0. Where a connection block is employed instead of a power lead, the metal housing must be connected to the earth terminal on the block. The provision made for earthing the luminaire must in all other respects satisfy the requirements laid down for Class I. Class II - symbol Class II luminaires are so designed and constructed that exposed metal parts cannot become live.This can be achieved by means of either reinforced or double insulation, there being no provision for protective earthing. In the case of a luminaire provided with an earth contact as an aid to lamp starting, but where this earth is not connected to exposed metal parts, the luminaire is nevertheless regarded as being of Class I. A luminaire having double or reinforced insulation and provided with an earth connection or earth contact must be regarded as a Class I luminaire. However, where the earth wire passes through the luminaire as part of the provisions for through-wiring the installation, and it is electrically insulated from the luminaire using Class II insulation, then the luminaire remains Class II. Class III - symbol The luminaires in this class are those in which protection against electric shock relies on supply at Safety Extra-Low Voltage (SELV), and in which voltages higher than those of SELV (50 V a.c. r.m.s.) are not generated. An a.c. operating voltage of 42 V maximum is common. A Class III luminaire should not be provided with a means for protective earthing.
