exceed 65°C, the temperature of the surface might reach high values and therefore under these
conditions the products need to be protected against accidental contact. We recommend that operators
who plan to use this product at these high temperatures stick a warning sticker, in accordance with IEC
60417-5041 (DB:2002-10), on a visible part of the device, or attach a sticker with the following text:
