E.3 Device Labeling
Check the labels provided by the manufacturer or the healthcare facilities are present and legible.
■
Main unit label
■
Integrated warning labels
E.4 Protective Earth Resistance
1. Plug the probes of the analyzer into the device’s protective earth terminal and protective earth terminal of
the AC power cord.
2. Test the earth resistance with a current of 25 A.
3. Verify the resistance is less than limits.
LIMITS
For all countries, R = 0.2 Ω Maximum
E.5 Earth Leakage Test
Run an Earth Leakage test on the device being tested before performing any other leakage tests.
The following outlet conditions apply when performing the Earth Leakage test:
■
normal polarity (Normal Condition),
■
reverse polarity (Normal Condition),
■
normal polarity with open neutral (Single Fault Condition),
■
reverse polarity with open neutral (Single Fault Condition)
LIMITS
For UL60601-1,

E.6 Patient Leakage Current
Patient leakage currents are measured between a selected applied part and mains earth. All measurements have
a true RMS only
The following outlet conditions apply when performing the Patient Leakage Current test.
■ normal polarity (Normal Condition);
■ reverse polarity (Normal Condition),
■ normal polarity with open neutral (Single Fault Condition);
■ reverse polarity with open neutral (Single Fault Condition).
■ normal polarity with open earth (Single Fault Condition);
■ reverse polarity with open earth (Single Fault Condition).
LIMITS
For CF applied parts
◆
10 μA in Normal Condition
◆
50 μA in Single Fault Condition
