Basic Safety and Essential Performance
Instructions for maintaining basic safety and essential performance with regard to
electromagnetic disturbances for the expected service life:
•
Perform preventive maintenance on the device on an annual basis.
•
Follow service procedures as defined in the service manual to ensure EMC performance.
•
Be prepared to use a manual aspiration technique if the use location is near (e.g. less than
1.5 km from) AM, FM, or TV broadcast antennas.
Electrical
The Model 330 Aspirator uses an external medical power supply (Jasper AC/DC power supply
REF : 9141-000-127) which meets safety standards UL60601-1 / EN60601-1 for both Class I
and II. This means the power supply employs both double insulation and a protective earth
ground as means of patient and operator protection, as explained below.
Class I
This equipment incorporates basic insulation for protection under normal conditions and is
earthed for protection under single-fault conditions. This method relies on protection from
electric shock by providing the basic insulation and earthing. (This is the method most used
with stationary equipment where exposed metal parts and/or the chassis/enclosure is metal.)
Class II
This equipment incorporates basic insulation for protection under normal conditions but a
second barrier of insulation (additional layer(s) of insulation) is added for protection under the
single fault conditions. In other words, this method relies on the two layers of insulation for the
protection from electric shock. This method is more common in portable devices where
connection to earthing is not possible in all use environments.
