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.
The housing using plastic insulation material and the heater plate plating the insulating anodizing layer.
Protect of any person from electric shock hazards.
The value of their earth leakage current tested prior to commissioning and at regular intervals during their
service life. The mains plug and any part that is protectively earthed shall not exceed 0.2 Ω
as shown in
Figure.
(Refer to IEC/EN 60601-1 §8.6.4)
4.1.6. Breathing Circuit
Breathing circuit is a single use when you use a period of time or dirty, please replace the new product
directly.
