Electrical safety tests are used to timely detect potential electrical safety risks that
might cause injuries to patients, operators or maintenance personnel. Electrical
safety tests must be carried out under normal environmental conditions (that is,
normal temperature, humidity and barometric pressure).
The electrical safety tests described in this chapter take 601 safety analyzer as an
example. The safety analyzer used in different regions may vary. Make sure that the
electrical safety test scheme you adopted is applicable.
Equipment connection is shown in the following figure.
EUT
A: AC power (programmable power supply, frequency control) B: Isolation transformer in leakage current test tooling C: Security tester
Tools required:

Safety analyzer

Isolation transformer
3.6.1 Enclosure Leakage Current Test
1. Connect the 601 safety analyzer to a 264 V AC 60 Hz power supply.
2. Connect the application part of the EUT through the application part connection
tooling. Connect the SUM terminal of the application part connection tooling to
the RA terminal of the safety analyzer.
3. Use the power cord to connect the EUT to the auxiliary power output connector
of the 601 safety analyzer.
4. Connect one end of the red lead to the "Red input terminal" of the safety
analyzer, and clip the other end on the metal foil attached on the surface of the
outer housing of the EUT.
5. Power on the 601 safety analyzer. Press 5-Enclosure leakage on the panel of
the 601 safety analyzer to access the screen for enclosure leakage current test.
6. The enclosure leakage current is not greater than 100 µA in normal condition
and is not greater than 500 µA in single fault condition.
