Electrical safety of V-unit or ME system according to DIN EN 62353 (IEC 62353) NOTE The medical device under test conforms to the conditions of protection class I. With the MCable-Mainstream CO2 module M11.1 (CO2 sensor) (sensor connected) or the neonatal flow sensor the medical device conforms to type BF.
NOTE The tester, e.g. SECUTEST, must be correctly configured for all measurements. If implausible measurement results are obtained, such as a leakage current of 0.0 µA, check the tester configuration in addition to the test setup!
NOTE In testing to IEC 62353, the medical electrical device (ME device) or the medical electrical system (ME system) must be tested. ME systems must be treated like ME devices. An ME system is a combination of several devices, as specified by the manufacturer, of which at least one must be an ME device, which are interconnected by a functional connection or by means of a multiple socket outlet.
NOTE In the case of devices connected to other devices by a data cable, this connection must be disconnected prior to performing the electrical safety test, in order to avoid false measurements.
3.1.1
Visual inspection Prerequisites
The tester and the device under test are switched off.
WARNING Hazardous voltage. Touching live components can lead to serious injury or death. ► Disconnect the power cord from the AC outlet before checking the power fuse-links. Action Test
• Disconnect the power plug from the mains socket. – The power fuse-links of the device under test match the specifications on the rating plate. – The power cable and plug are not dirty or damaged. Condition checked.

• Establish the test setup. • Switch on the testing device. • Configure the testing device appropriately and follow its instructions. • Using the tip of the probe cable, scan each of the measuring points on the device under test listed under "Protective earth resistance measuring points" one after the other, moving the mains power supply cord along the entire length during the measurement. The resistance must not change when you do so.

Device leakage current
NOTE The equipment leakage current can be tested by the differential measurement method or the direct measurement method. In direct measurement, set up the device under test with insulation and scan all accessible conductive components using the probe (the protective earth is internally interrupted in the tester).

• Establish the test setup. • (Applied part) Connect one side of the test adapter to the device under test and the other side to the tester, configurable port "A" for applied parts (observe the configuration!). • Follow the instructions given by the tester.
The test must be performed twice on symmetrical mains plugs. In the second test the mains plug must be rotated through 180° before being plugged into the socket. In many test devices the mains plug rotation is simulated by means of a built-in selector switch. The higher measured value must be documented.

Test setup for protective conductor resistance
Item Designation 1 2 3 L N PE Action
Tester, e.g. SECUTEST, 7910594 Device under test Test probe with tip (e.g. SECUTEST accessories) Conductor Neutral conductor (Protective Earth) conductor
• Prepare the test setup. • Switch the tester on. • Configure the tester appropriately, and follow the instructions on the tester. • Using the tip of the test probe, scan the following points on the V-unit, moving the power cable section-by-section while doing so: – Power supply unit potential equalization pin

• Prepare the test setup. • Switch on medical device. • Follow the instructions on the tester.
NOTE For symmetrical mains plugs that have no preferential position in the socketoutlet, the earth leakage current test must be performed twice! The second test is performed with the plug rotated 180° in the socket. In many test devices the mains plug rotation is simulated by means of a built-in selector switch. The higher measured value must be documented. IEC 60-601-1 Test Result Test Result

Patient leakage current
NOTE A patient leakage current measurement is only performed in neo-flow measurement. With the MCable-Mainstream CO2 sensor option no patient leakage current measurement is performed, as the electrical isolation is in the sensor head and the sensor has no metallic contacts. A visual check is performed alternately in the "Condition tests" section.

Tester, e.g. SECUTEST, 7910594 Device under test Test plug, 7901772 Ports for applied parts Conductor Neutral conductor (Protective Earth) conductor
• Prepare the test setup. • Connect the Neo-Flow sensor cable to the V-unit. • Remove the Neo-Flow sensor. • Connect the test plug (7901772) to the Neo-Flow sensor socket and to the tester. • Start up the test specimen and perform patient leakage current measurements. • Follow the instructions on the tester.
