These boxes shall

39、be bonded to the inner side of the heated glass pane.All necessary precautions concerning insulation and earthing of the installation to protect against electrical shock shall be taken. For requirements, see IEC 60092-101.If in special cases the connection box has to be installed on the glassframe o

40、r main frame of the windows, this shall be especially agreed between supplier and customer. In such cases, the glass pane will need to be equipped with suitable cables.5.4 Overheating protectionHeated glass panes shall be equipped with temperature-limitation devices (regulators) to ensure the heated

41、 glass pane does not overheat. Electric power to the heated glass pane must be switched off to ensure the temperature of the glass pane surface does not exceed 50 C. Two types of such a regulator are specified: Single regulation (S): the regulator (e.g. a temperature sensor) is mounted directly on t

42、he glass pane (interior-side). It affects only the relevant glass pane and is part of original equipment. Group regulation (G): a separate regulation device not mounted directly at the window to which several glass panes are connected appropriately. Relevant information on type and number of these r

43、egulation devices is necessary at the time of ordering.11DIN ISO 3434:2015-126 TestsTests shall be carried out by the heated glass manufacturer.6.1 Electrical testsA voltage test shall be carried out on each finished heated glass pane.
