Safety Tests
The monitor safety tests meet the standards of, and are performed in accordance with,
IEC 60601-1, Clause 19 (Second Edition, 1988; Amendment 1, 1991-11, Amendment 2,
1995-03), EN60601-1 for instruments classified as Class I and Type CF.
Protective Earth Continuity
This test checks the integrity of the power cord ground wire from the AC plug to the
instrument chassis ground. The current used for this test is less than or equal to 4 Volts
RMS, 50 to 60 Hz, and 25 Amperes.
1. Connect the monitor AC power plug to the analyzer as recommended by the analyzer
operating instructions.
2. Connect the analyzer resistance input lead to the equipotential terminal (ground lug) on
the rear of the instrument. Verify that the analyzer indicates 100 milliohms or less.
Electrical Leakage
Earth Leakage Current
This test is in compliance with IEC60601-1 earth leakage current. The applied voltage for
IEC60601-1 is 264 Volts AC, 50 to 60 Hz. All measurements shall be made with the
power switch in both “On” and “Off” positions.
1. Connect the monitor AC plug to the electrical safety analyzer as recommended by the
analyzer operating instructions.
2. Perform the test as recommended by the analyzer operating instructions.
Table 3. Earth Leakage Current Values
Test Condition Allowable Leakage Current (microamps)
Normal Condition (NC) 500
SFC Open Supply (SFC OS) 1000
Normal Condition RM (NCRM) 500
SFC Open Supply RM (SFC OSRM) 1000
SFC: Single Fault Condition / RM: Reverse Mains/Lines Voltage
Note: Earth leakage current is measured under various conditions of the AC power and
protective earth conductor. For each condition, the measured leakage current must
not exceed that indicated in Table 8.
Enclosure Leakage Current
This test is in compliance with IEC60601-1 enclosure leakage current. This test is for
ungrounded enclosure current, measured between enclosure parts and earth. The applied
voltage for IEC60601-1 is 264 Volts AC at 50 to 60 Hz.
1. Connect the monitor AC plug to the electrical safety analyzer as recommended by the
analyzer operating instructions.
2. Place a 200cm
2
foil in contact with the instrument case making sure the foil is not in
contact with any metal parts of the enclosure that may be grounded.
3. Measure the leakage current between the foil and earth.
