E-4 Electrical Safety Inspection

LIMITS
For BF applied parts:

100 μA in Normal Condition.

500 μA in Single Fault Condition.
E.8 Mains on Applied Part Leakage
The Mains on Applied Part test applies a test voltage, which is 110% of the mains voltage using a limiting
resistance, to selected applied part terminals. Current measurements are then taken between the
selected applied part and earth. Measurements are taken with the test voltage (110% of mains) on
applied parts in the normal and reverse polarity conditions.
The following outlet conditions apply when performing the Mains on Applied Part test.

Normal Polarity;

Reversed Polarity.

LIMITS

For BF
applied parts: 5000 μA.
E.9 Patient Auxiliary Current
Patient Auxiliary currents are measured between any selected Applied Part connector and the remaining
Applied Part connectors. All measurements may have a true RMS response.
The following outlet conditions apply when performing the Patient Auxiliary 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 BF applied parts,
 100 μA in Normal Condition.

500 μA in Single Fault Condition.
NOTE: Make sure the safety analyzer is authorized and complies with the requirements of IEC61010-1.
Follow the analyzer manufacturer's instructions.
