Functional and electrical safety checks: Electrical safety tests
8-14 Dash 3000/4000/5000 2000966-542D
Patient (sink) leakage current test (mains voltage on the applied
part)
This procedure only applies to Class I (grounded/earthed) equipment,
and measures the leakage current from a mains voltage source into the
ECG/RESP connector or the SpO2 connector.
The patient connector test body shorts all signals in the connector
together. Refer to the instructions contained with the safety analyzer to
perform this test. Connect the ECG/RESP Test Body to the green
connector of the device under test.
Refer to the instructions contained with the safety analyzer to perform
each test.
NOTE
*The MD represents the network and voltage measuring instrument
and its frequency characteristics per IEC 60601-1.
** Per IEC 60601-1, the impedance to protect the circuitry and the
person performing the test, but low enough to accept currents higher
than the allowable values of the LEAKAGE CURRENT to be
measured.
1. Configure leakage tester as follows:
Polarity – NORMAL
Neutral – CLOSED
GND (Earth) – CLOSED
WARNING
Shock hazard. The following step causes high voltage at
the test body. Do not touch the test body.
Closed
(Keep cable length as
short as possible.)
