4.1.5. Safety The resistance to earth from protectively earthed parts in the unit shall be low enough to permit adequate fault current to flow in the event of insulation failure, thereby ensuring that the protection device in the final sub-circuit opens quickly. The protective earthing conductor also ensures that most of the capacitive leakage current from the mains part in the unit flows via a low-resistance path to earth and does not appear as excessive leakage current from the device enclosure or as Applied Part current, when the earthing conductor is intact. - Page 17 While the chamber temp higher than 41°C, system will alarm with sound. NOTE：Alarm will be unworkable and it will only have twinkle yellow indicator while in Non-Heater Wire Mode, and alarm will happen while the chamber higher than 66°C. 5.
