4 Testing and Maintenance
This safety test is based on IEC/EN 62353.
For measurement limits, refer to Safety (2) test, Test and Inspection Matrix.
Report the highest value (X1).
Test
Equipment Leakage Current Test (Normal
Condition - with mains cable)
All values for current and voltage are the root mean square (r.m.s.) values, unless otherwise stated.
N O T E
In case of an IT-power system, this safety test measurement requires a special measuring circuit, for
example with its own integrated TN-system or use of an external isolation transformer attached to the
safety test device.
S(3) Equipment Leakage Current Test - Single Fault Condition
Test to perform:
Measuring circuit for the measurement of Equipment Leakage Current - Direct method according to
IEC/EN 62353.
This test measures leakage current of accessible conductive and non-conductive metal parts of the
monitor and the functional earth leakage current. It tests normal and reversed polarity. Perform the test
with S1 open (Single Fault Condition).
There are no parts of the equipment that are not protectively earthed. Disconnect any data cables and
any connections that may provide an extraneous earth path. Test the device under test (DUT) on an
insulated surface. Do not touch the DUT during testing.
This safety test is based on IEC/EN 62353.
For measurement limits, refer to Safety (3) test, Test and Inspection Matrix.
Report the highest value (X2).
