S(1): Detachable Power Cord Protective Earth Test (optional)
This test can be performed upon request by the customer. Test to perform:
Use an Ohmmeter to measure the earth wire resistance of the detachable power cord. This safety test
is based on IEC/EN 60601-1, IEC/EN 62353, UL2601-1 Ed. 2/UL60601-1:2003 and CSA 601.1-
M90. Report the highest value (X1).
NOTE
• If the protective earth resistance test fails, testing must be discontinued immediately, and the
device under test must be repaired or labeled as defective.
• Flex the power cord during the protective earth resistance test to evaluate its integrity. If it does
not pass the test, exchange the power cord.
• The functional earth conductor is required for EMC purposes. It has no protective function
against electrical shock. The protection against electrical shock is provided by double and/or
reinforced insulation.
