Electrical safety This chapter contains tests on the electrical safety. Perform the tests according to IEC 62353 or IEC 60601-1 (depending on the national guidelines. In Germany, for example, standard DIN EN 62353 applies).

3.1

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

No.0806_0000007435

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!

Electrical safety

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 With devices that are connected to other devices by means of a data cable, this connection must be disconnected prior to performing the electrical safety check, in order to avoid incorrect 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.

Application components for measurement of leakage current from application component

NOTE Only conduct the leakage current test from the applied part if the Neoflow measurement option is available. With the optional MCable Mainstream CO2 sensor, no measurement of the patient leakage current is performed due to the galvanic isolation in the sensor head and the sensor having no metallic contacts. As a substitute, a visual inspection is performed in the Condition test chapter.

Tester Device under test Applied part, device-specific test adapters for tester Configurable connection sockets for applied parts (A - K) Conductor Neutral conductor Protective earth

• Prepare the test setup. • (Applied part) Connect the device-specific test adapter on one end to the device under test and on the other end to the tester's configurable port "A" for applied parts (paying attention to the configuration!). • Follow the instructions on the tester.

The 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.

NOTE The reference value (initial measured value) must always be transmitted!

NOTE If the measured values are between 90% and 100% of the permissible limit value, the reference value and the previously measured values of the recurrent test should be applied to assess electrical safety! Test Result Test Result

Electrical safety according to IEC 60601-1 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 An optional multiple socket-outlet, if any, must be included in the individual tests (medical electrical system).

NOTE With devices that are connected to other devices by means of a data cable, this connection must be disconnected prior to performing the electrical safety check, in order to avoid incorrect measurements.

3.2.1

Visual inspection Prerequisites

The following preconditions must be met for the visual check: – The medical device is switched off. – Make sure the power plug is unplugged. – The pipeline supply tubing has been removed.

Test

– The ratings of the V-unit power fuse links conform to the specifications imprinted on the power supply unit label. – The mains power cable and cable retainer of the V-Unit are not dirty or damaged. Condition checked.

• 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.

Patient leakage current

NOTE Perform the patient leakage current test only if the Neo-Flow measurement option is fitted. 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 test" section.

• 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.

For symmetrical mains plugs that have no preferential position in the socketoutlet, the patient 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.
