2.2 Electrical Safety
Type of protection against electric shock
Class I Equipment
CLASS I EQUIPMENT in which protection against electric shock does not rely on basic insulation only, but which
includes an additional safety precaution in that accessible conductive parts are connected to the protective earthing
conductor in the electrical installation in such a way that accessible parts cannot become live in the event of a failure of
the basic insulation.
Degree of protection against electric shock
Type BF Applied part
(for Probes marked with BF symbol)
TYPE BF APPLIED PART providing a specified degree of protection against electric shock, with particular regard to
allowable LEAKAGE CURRENT
BF: Isolation from ground; max. Patient leakage current: normal mode
≤
100 µA, single fault condition
≤
500 µA
Level of protection against harmful ingress of water
Parts of probe likely to come into contact with operator or patient meet the requirements of drip-proof
equipment (IPX1)
Parts of probe intended to be immersed in normal use meet the requirements of watertight equipment (IPX7)
The IP Classification of System is Ordinary Equipment (IPX0)
The Equipment is not suitable for use in the presence of a flammable anesthetic mixed with air (with oxygen or with
oxide)
Mode of operation
Continuous Operation
For maximum safety, always follow these guidelines:
Proper grounding of the system is critical to avoid electric shock. For protection, ground the chassis with a
three-wire cable, and plug the system into three-hole outlet.
Do not remove or circumvent the grounding wire.
