Information on the ground wire resistance test 1
Observe the instructions in the safety rules for installation and repair
(ARTD-002.731.17 ...).
The ground wire resistance must be measured after every intervention in the system.
However, documentation of the measured values is required only during periodical
safety checks.
If parts/components that can decisively influence the ground wire resistance are replaced
(e.g. replacement of the mains cable, replacement of the ON/OFF assembly, replacement
of multi-core connection cables, which also make the ground wire connection between
parts of the system (e.g. monitor cable or C-arm cable)), or if ground wire connections
have been repaired, then the ground wire resistance must be measured. The values must
be documented and evaluated in the ground wire resistance protocol.
The measurement must be made according to DIN VDE 0751, Part 1 (see ARTD Part 2).
In this case the ground wire resistance in the normal operating condition to all conductive
touchable parts of the system must be measured.
Make sure that control cables or data cables between the system components do not imi-
tate a ground wire connection.
During the measurement the power cable and additional connection cables which also
make the ground wire connection between parts of the system (e.g. monitor cable
between C-arm chassis and monitor trolley) must be moved section by section to detect
broken conductors.
The ground wire resistance must not exceed 0.2 ohms.
Danger of infections due to pathogens!
Non-compliance can lead to severe injuries and even death.
This product can be contaminated by infected blood or other
bodily fluids.
Avoid all contact with blood or other bodily fluids!
Strictly observe the safety information in ARTD-002.731.37...
regarding prevention of infectious diseases during customer ser-
vice calls.
Evaluate the results by comparing the first measured value to the
corresponding values documented during preceding mainte-
nance procedures or safety checks.
A sudden or unexpected increase of the measured values,
even if the limit value of 0.2 ohms is not exceeded,
indicates errors in the ground wire connections.
(Ground wire or contacts).
