WARNING
Electrical voltage!
Non-compliance can lead to severe injury and even death.
¹ The system leakage current measurement may be per-
formed on systems of protection class I only after the
protective conductor test has been passed.
First measured value
In the case of systems thoroughly tested at the factory prior to delivery, the system leak-
age current measurement was already performed at the factory and the measured value
was recorded in the system test protocol.
The measurement was performed using the line voltage and line frequency, the measur-
ing procedure, and the measuring equipment recorded in the system test protocol.
The test protocol is included with the accompanying documentation.
When the line voltage and line frequency match, the value recorded in the test protocol
must be used as the first measured value in the system leakage current protocol.
If the local line voltage or line frequency differs from the delivery state of the system or if
no measurement was performed and recorded at the factory, the system leakage current
must be measured.
If the local line voltage or line frequency differs from the delivery state of the system, the
values listed in the test protocol are invalid.
The values must be labeled invalid. The reason for newly determining the first measured
value must be documented and confirmed with date, name, and signature.
Adjust/program the system to the local line voltage/line frequency before the measure-
ment.
In the case of systems with no measured values for the system leakage current measure-
ment recorded in the system test protocol, the system leakage current measurement must
be performed after all work has been completed.
Measurement
Perform the measurement according to DIN VDE 0751, Part 1 (see ARTD-002.731.17....),
and record the determined value as the first measured value.
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
device and any additional manufacturer information restricting the use of the measuring
device.
