Information On The Protective Conductor Resistance Test - Siemens ARCADIS Varic Start-Up Instructions

General information

Information on the protective conductor resistance test

Observe the instructions in the "Safety Rules for Installation and Repair"
(ARTD-002.731.17 ...).
The protective conductor resistance of 0.2 ohms must not be exceeded.
First measured value
In the case of systems thoroughly tested at the factory prior to delivery, the protective con-
ductor resistance test was already performed and the measured values were recorded in
the system test protocol.
The measurements were performed using the measuring procedures and measuring
equipment recorded in the system test protocol.
The test protocol is included with the accompanying documentation.
If no covers were opened while installing the system and no additional components (e.g.
options) were installed or modified, the values recorded in the test protocol including the
measuring point (e.g. cover of the basic unit or cover of the image intensifier) can be
transferred to the protective conductor resistance protocol as the first measured values.
If the power plug was changed during system installation, covers were removed, or addi-
tional components were installed or modified, the values provided in the test protocol are
invalid.
The values must be labeled invalid. Cross out the values, enter the comment "invalid
value" and confirm this with name, date and signature.
The protective conductor test must be performed again after all work has been completed.
In the case of systems with no measured values for the protective conductor test recorded
in the system test protocol, the protective conductor test must be performed after all work
has been completed.
Measurement
The measurement must be performed in accordance with DIN VDE 0751, Part 1 (refer to
ARTD Part 2). The protective conductor 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 system components are not
mistaken for protective conductor connections.
During the measurement, the power cable and additional connection cable with the inte-
grated protective conductor (e.g., monitor cable between the basic unit and monitor cart)
must be moved section by section to detect cable breaks.
The protective conductor resistance must not exceed 0.2 ohms.
The values, including the measuring points, must be recorded as first measured values in
the protective conductor resistance protocol.
The measuring procedure and the measuring device used (designation and serial num-
ber) must also be documented.
