Safety-related checks

VI
The Invia Liberty is a device in protection class II (EN IEC 60601-1, A1, A2:1995), the safety-
related checks are confined to visual inspection of the housing and main power cord for
damage. This check must be performed prior to each use.
Devices of protection class II do not have a protective earth conductor; there is therefore no
need to check the earth leakage current!
The Invia Liberty enclosure is made entirely of insulated material. Tests of the enclosure leaka-
ge current using common measuring instruments will therefore not reveal measurable values.
Even when suctioning a conductive fluid until the overflow protection device activates (9 g/l
NaCl; EN ISO 10079-1;1999), measurements of the patient leakage current using common
measuring instruments will not reveal measurable values.
Invia Liberty does not have patient circuits or functional earth connections.
