Mindray iPM-9800 - Enclosure Leakage Current Test; Earth Leakage Current Test

3-20
Tools required:
 Safety analyzer
 Isolation transformer
3.7.1 Enclosure Leakage Current Test
1. Connect the 601 safety analyzer to an AC power supply (264 V, 60 Hz).
2. Connect SUM terminal of the applied part connection apparatus to RA input terminal
of 601 safety analyzer, another terminal to the applied part of EUT.
3. Connect the EUT to the analyzer’s auxiliary output connector using a power cord.
4. Attach one end of the red lead to the “Red input terminal” of the analyzer, and the
other end to tinsel over the enclosure of the EUT.
5. Power on the 601 safety analyzer and then press the “5－Enclosure leakage” button on
the analyzer’s panel to enter the enclosure leakage test screen.
6. Under normal condition, the enclosure leakage current should be no greater than 100
µA. Under single fault condition, it should be no greater than 300 µA.
3.7.2 Earth Leakage Current Test
1. Connect the 601 safety analyzer to an AC power supply (264 V, 60 Hz).
2. Connect SUM terminal of the applied part connection apparatus to RA input terminal
of 601 safety analyzer, another terminal to the applied part of EUT.
3. Connect the EUT to the analyzer’s auxiliary output connector using a power cord.
4. Power on the 601 safety analyzer and then press the “4－Earth leakage” button on the
analyzer’s panel to enter the earth leakage test screen.
5. Under normal condition, the earth leakage current should be no greater than 300 µA.
Under single fault condition, it should be no greater than 1000 µA.
