1.5 Safety information and protective measures
WARNING Risk of death, injuries or material damage
Non-compliance can lead to death, injuries or material damage.
Please observe:
¹the product-specific safety information in these instruc-
tions
¹the general safety information in the document
TD00-000.860.01... and
¹the safety information according to ARTD part 2.
WARNING X-ray radiation!
Non-compliance can lead to illness, irreversible damage to body
cells and genetic material, severe injuries and death.
When working on the unit which requires release of radiation, the
radiation protection guidelines and the radiation protection rules
according to ARTD-002.731.02... must be observed.
Observe the following:
¹Use available radiation protection equipment.
¹Wear radiation protective clothing (lead apron).
¹Keep distance to radiation source as large as possible.
¹Only release radiation if necessary.
¹Set radiation as low as possible (low kV and mAs val-
ues).
¹Release radiation as briefly as possible.
X¹Checks that require radiation to be released are marked
by the radiation warning symbol displayed on the left.

DANGER When working on the open unit there is a risk of electrical shock!
Non-compliance can lead to injuries or death.
Observe the following:
¹The capacitor bank can still be charged. Do not attempt
to work on the system while this condition exists.
¹After switching off the system, approximately 450 VDC
(350 VDC for Serial No. < 10100) may still be present in
the system even after disconnecting the line voltage
plug. Within 10 minutes this voltage will drop to approxi-
mately 10 V.
¹Always measure the actual voltage present with the DVM
at test points -VCC and + VCC on the D 960 inverter
board or (more accessible) on the D 970 capacitor board
at the + connection point of capacitor C3 and on the right
side of fuse F3 (Fig.2/p.9).
¹LEDs V1 ... V10 on D 970 go out at a significantly higher
voltage level and are therefore not reliable safety indica-
tors.
¹If a fuse on the D 970 has responded, high voltage may
still be present at the affected capacitor even after a pro-
longed period of time.
¹The capacitor discharge circuit utilizes the D925 board,
CS and LS relays. If connectors X3 or X9 on D 925 or D
950 are not inserted or if there is a defect in the circuit,
the C-bank will not discharge. This can cause life-threat-
ening voltage to be present in the system even after a
prolonged period of time.
¹Also refer to the Polymobil Plus Service instructions
SPR8-125.061... "Replacing the capacitor bank".
•Connect the Polymobil Plus only to a line voltage supply (line voltage receptacle) that
complies with the requirements of VDE 0107 or corresponds to the local national regu-
lations.
•Disconnect the Polymobil Plus at the line voltage OFF switch on the operating console
and disconnect the line voltage plug prior to performing any service work.
•Remove or insert boards with the generator switched OFF only; observe ESD guide-
lines when handling boards.

1.7 Information on the protective conductor resistance test
Observe the information in the “Safety rules for installation and maintenance”
(ARTD-002.731.17...).
The protective conductor resistance is to be measured, documented and evaluated during
maintenance.
NOTE For evaluation, the value first measured and values documented
during previous maintenance or safety checks are to be compared
to the measured values. A sudden increase of the measured val-
ues, even if the limit value of 0.2 Ohm is not exceeded, indicates
errors in the protective conductor connection (protective conduc-
tor or contacts).
Measurement is to be carried out according to DIN VDE 0751, part 1 (see ARTD part 2).
In doing so, the protective conductor resistance to all conductive and accessible parts is
to be measured in the normal operating status of the unit.
Make sure that control or data cables between components of the unit do not simulate a
protective conductor connection.
During measurement, the power supply cable and additional connection cables with inte-
grated protective conductor are to be moved section by section in order to detect breaks
in the cables.
The protective conductor resistance must not exceed 0.2 Ohm.

disconnected from power, in compliance with DIN VDE 0751-1/2001-10, Fig. C2.

The values that were determined are to be logged and evaluated in the report “Protective
conductor resistance / report” by indicating the measuring points.
In addition, the measuring procedure and the measuring device used (designation and
serial number) are to be documented.
NOTE The report “Protective conductor resistance / report” is filed in the
“Certificates” register in the system folder.
NOTE If documentation of protective conductor resistance measure-
ments is missing, a new report must be created.
A new report “Protective conductor resistance / report” is included
in the SPR8-125.034.02.02 startup instructions. Detach this report
from these instructions, complete it and file it in the “Certificates”
register in the system folder. For a first determination, the deter-
mined values are to be logged as values measured for the first
time. Evaluation is not required in this case.

1.8 Information on the device leakage current measurement
NOTE During maintenance, the device leakage current measurement is
to be carried out and logged as repeated measurement.
However, under the following circumstances the value first mea-
sured is to be determined again and a new report is to be created:
- If documentation of device leakage current measurement is miss-
ing.
- If local mains voltage deviates from the mains voltage document-
ed in the report (e.g. in case of change of location / change of op-
erator).
- When using another measuring process for measuring the device
leakage current than that documented in the report.
For traceability, the newly created report is to be referenced in
writing on the old report. The reason for new determination of the
value which was first measured is to be documented and con-
firmed with name and signature.
Observe the instructions in the “Safety rules for installation and maintenance”
(ARTD-002.731.17...).
WARNING Electrical voltage!
Non-compliance can lead to severe injuries even resulting in
death.
¹The device leakage current measurement for devices of
protection class I may only be carried out after protective
conductor tests were carried out successfully.
First measured value
The first measured value was determined already and documented in the report “Device
leakage current / report”. The measuring method was also logged.
Measurement was carried out with the logged mains voltage and the logged measuring
devices.
Measurement
Measurement is to be carried out according to DIN VDE 0751, part 1 (see
ARTD-002.731.17...) and the determined value is to be logged.
The measuring method indicated in the report is to be used for this.
If the value first measured needs to be determined again (see instructions above), either
direct measurement or differential measurement can be selected.

Measuring the device leakage current according to the differential current method (mea-
suring setup according to (Fig.4/p.15)) is the preferred method, as the person carrying
out the measurement or other persons are not endangered during the measurement.
However, observe the minimum resolution of the leakage current measuring device and
additional manufacturer specifications which limit usage of the measuring device.

method in compliance with DIN VDE 0751-1/2001-10, Fig. C6 for protection class I.
Pos. 1 = System
Pos. 2 = Application part type B (if available)
Pos. 3 = Measurement setup (integrated into measuring device)
If direct measurement of the device leakage current is used (measuring setup according
to (Fig.5/p.16)), the system must be installed in an insulated way and must not be
touched during measurement.

WARNING Electrical voltage!
Non-compliance can lead to serious injuries or even death.
¹When measuring device leakage current directly, during
measurement, no housing parts of the unit must be
touched (Fig.5/p.16)).
¹Access to the unit by third parties must be prevented.
The unit must be switched on during measurement. Therefore, measuring devices with
automated measuring procedure must be set to manual measuring.
The highest value must be entered into the report “Device leakage current / report”.
This value must not exceed the permissible leakage current values according to DIN VDE
0751-1/2001-10, Table F.1, line “Device leakage current for units according to remarks 1
and 3”, of 2.5 mA.
The actual mains voltage is to be measured and logged. If the measured mains voltage
deviates from the nominal voltage, the measuring value is to be corrected to the value
which corresponds to a measurement with the nominal value of the mains voltage. This is
to be additionally documented.

The measuring method (differential measurement or direct measurement) and the mea-
suring device used (designation and serial number) are to be documented.
For repeated measurements, the measuring value is to be evaluated additionally.
NOTE For evaluation, the value first measured and the values document-
ed during previous maintenance or safety tests are to be com-
pared with the measured values. A sudden increase of the
measured values, even if the limit value of 2.5 mA is not exceeded,
indicates errors in the primary circuit of the mains voltage supply
(insulation damages, damages due to dampness, faulty suppres-
sor element or similar).
In case of new determination, evaluation is not required.
The report “Device leakage current / report” is to be filed in the “Certificates” register in the
system folder.
NOTE The report “Device leakage current / report” is filed in the “Certifi-
cates” register in the system folder.
NOTE If documentation of device leakage current measurement is miss-
ing, a new report must be created.
A new report “Device leakage current / report” is included in the
startup instructions SPR8-125.034.02.02. Detach the report from
this instruction, complete it and file it in the “Certificates” register
in the system folder. For a first determination, the determined val-
ues are to be logged as values measured for the first time. Evalu-
ation is not required in this case.
