Notes on equivalent leakage current measurement
0
Applicability and regulations for regional companies
0
The equivalent leakage current must be measured where applicable under the require-
ments of DIN VDE 0751 Part 1. Outside of the scope of application of DIN VDE 0751, the
following rules are to be adhered to for the regional companies: (also see ARTD part 2,
Security Rules for Assembly and Maintenance).
The national regulations apply primarily for the regional companies. In the event that there
are no existing regulations, the following provisions should be adhered to in the interest of
the safety of customers, patients, employees and third parties as well as the company.
First measured value
0
The equivalent leakage current measurement was performed at the factory and the mea-
sured value was entered in test protocol 1b. The measurement was made at the line volt-
age and line frequency recorded in test protocol 1b. The test protocol 1b is filed in the log
book, register 3. When the line voltage and line frequency match, the value recorded in
test protocol 1b is to be transferred as the initial measured value to the equivalent leakage
current/protocol.
If the local line voltage or line frequency deviates from the delivery state of the ARCADIS
Orbic, the values listed in test protocol 1b are invalid. The values are to be labeled invalid.
(Check the comment "values invalid" and confirm with name, date, and signature). The
equivalent leakage current measurement must be repeated. Perform the measurement
according to DIN VDE 0751, part 1 (see ARTD, part 2), and record the determined value
as the initial measured value. This value must not exceed the maximum value of 2 mA for
equivalent leakage currents for devices according to IEC 601 part 1/VDE 0750 part 1. The
initial measured value is to be entered in the equivalent leakage current protocol
age current measurement / p. 39)
. Comply with the measuring arrangement according to
. The system must be switched on during the measurement. When the
Bender safety tester is used, this must therefore be set to manual measurement. Sepa-
rate the page with the protocol from these instructions and file it in the log book, system
folder.
Repeat measurement
0
When service or repair work is performed on the primary power supply circuit (e.g.,
repairs to the power-on circuit or replacement of the line filter), the equivalent leakage cur-
rent measurement must be repeated. Comply with the measuring arrangement according
to
. The system must be switched on during measurement. When the
Bender safety tester is used, this must therefore be set to manual measurement. The val-
ues measured in the repeat measurement may not exceed the threshold value of 2 mA as
specified in VDE 0751, Part 1 (see also ARTD, part 2). In addition, they may not exceed
the initial measured value by more than 50%. The system must be repaired if the limit is
exceeded. Document the measured value in the equivalent leakage current protocol.
