Ground wire resistance test information

Observe the instructions in the "Safety Rules for Installation and Repair" (ARTD-002.731.17 ...).

The ground wire resistance must be measured after every system intervention.

However, documentation of the measured values is required only during periodic safety checks.

If parts/components that can significantly influence the ground wire resistance (e.g. replacement of the power cable, replacement of the power-up module, replacement of multi-pole connection cables, which also create the ground wire connection between system parts (e.g. monitor cable or C-arm cable)) are replaced or if ground wire connections have been repaired, the ground wire resistance must be measured. The values must be documented and assessed in the ground wire resistance protocol.

NOTE		For evaluation purposes, the first measured value and the values
		documented during maintenance or safety checks must be com-
		pared to the measured values. A sudden or unexpected increase
		in the measured values may indicate a defect in the ground wire
		connections - even if the limit value of 0.2 ohms is not exceeded.
		(Ground wire or contacts).

The measurement must be performed according to DIN VDE 0751, Part 1 (see ARTD, Part 2). In this case, the ground wire resistance for all touchable conductive parts must be measured during the normal operating state of the system.

Make sure that control cables or data cables between the components of the system are not mistaken for a ground wire connection.

During the measurement, the power cable and additional connection cables, which also create the ground wire connection between system parts (e.g. monitor cable between the basic unit and monitor trolley,) must be moved section by section to detect cable breaks.

Ground wire resistance may not exceed 0.2 ohms.

System leakage current measurement information

NOTE		If parts in the primary circuit (e.g., power cable, line filter, power
		transformers, or complete power-on modules) are replaced during
		service work, the system leakage current measurement must be
		subsequently performed and recorded as a repeat measurement.
		However, the first measured value is to be newly determined and a
		new protocol is to be created under the following conditions:
		- Lack of system leakage current measurement documentation
		- Local line voltage or line frequency deviating from the line volt-
		age and line frequency values documented in the protocol (e.g., in
		the event of a site/operator change)
		- Use of a different procedure for measuring the system leakage
		current than the one documented in the protocol.
		For the purpose of traceability, reference to the new protocol must
		be made in the old protocol. The first measured value must be
		newly determined so that it can be documented and confirmed
		with a name and signature.

Observe the instructions in the "Safety Rules for Installation and Repair" (ARTD-002.731.17 ...).

WARNING Electrical voltage!

Noncompliance can lead to severe injury and even death.

The system leakage current measurement may be performed on units of protection class I only after the ground wire test has been passed.

First measured value

The first measured value was already determined and documented in the system leakage current protocol. The measuring procedure was also recorded.

The measurement was performed with the recorded line voltage, line frequency and measuring equipment.

Measurement

Perform the measurement according to DIN VDE 0751, Part 1 (see ARTD-002.731.17....), and record the determined value.

The measuring procedure indicated in the protocol must be used.

If the first measured value needs to be newly determined (see previous information), a measuring procedure can be selected (direct measurement or differential measurement).

Measurement of the system leakage current according to the differential current method (measurement setup according to (Fig. 2 / p. 15)) must be given preference, since this method is not dangerous to the person performing the measurement and other persons.

However, please note the minimum resolution of the system leakage current measuring instrument and any additional manufacturer's data restricting the use of the measuring device.

WARNING Electrical voltage!

Noncompliance can lead to severe injury and even death.

No housing parts of the system may be touched during direct measurement of the system leakage current (measurement setup according to (Fig. 3 / p. 16))

Third-person access to the system must be prevented.

The system must be switched on during the measurement. Measuring devices with automated measuring sequences must therefore be set to manual measurement.

The highest value must be entered in the system leakage current protocol.

This value must not exceed the permissible system leakage current values according to DIN VDE 0751-1/2001-10, Table F.1, line "system leakage current for units according to remarks 1 and 3" of 2.5 mA.

Measure and record the current line voltage. If the measured line voltage deviates from the nominal voltage, correct the measured value to the value corresponding to a measurement at the nominal value of the line voltage. This must also be documented.

Document the measuring procedure (differential measurement or direct measurement) and the measuring device used (designation and serial number).

In the case of repeat measurements, the measured value must also be evaluated.

NOTE		For evaluation purposes, the first measured value and the values
		documented during maintenance or safety checks must be com-
		pared to the measured values. A sudden or unexpected increase
		in the measured values may indicate that a fault has occurred in
		the primary power supply circuit (insulation damage, damage
		caused by humidity, defective interference suppressor, etc.) -
		even if the limit value of 2.5 mA is not exceeded.

Evaluation is not necessary in the case of a new determination.

The protocol sheet must be filed in the system folder or log book.
