Training of customer support engineers 1
Due to the technology, used in this equipment, the setup, service and maintenance
is only allowed to be performed by a customer support engineer with a Work Permit for
MOBILETT Plus HP.
Text emphasis 1
Symbols 1
Checks and adjustments that must be performed with radiation ON are identified by the
radiation warning symbol.
The symbol means "Dangerous voltage".
Checks marked with this symbol are to be entered into the test certificate at the end of
these instructions.
The symbol means "Attention, consult the documentation".
This symbol means: equal to or less than.
Several of the sections in these instructions are for the USA only. These sections are
identified with this symbol.
“Warnings” are information provided with special emphasis when
there is apotential for personal injury or life-threatening danger
to the operator or patient.
“Cautions” are information provided with special emphasis when
there is apotential for danger or damage to the equipment.
“Notices” are information provided with special emphasis to facil-
itate proper use of the equipment or proper execution of a proce-
dure.

Safety information and protective measures 1
•When performing service work and tests adhere to:
-the product-specific safety information in the documents,
-as well as the general safety information contained in ARTD
Part 2.
•Connect the MOBILETT Plus HP only to line voltage (receptacle),
that corresponds to the installation requirements of VDE 0107 or
country-specific regulations.
•Remove or installboards only when the generator is switched
OFF. Adhere to the ESD guidelines.
•Checks and adjustments performed with radiation ON are
identified by the radiation warning symbol . During these
types of adjustments, radiation protective clothing must be
worn.

Protective measures batteries B10 and capacitors in power
conversion unit M10 and M11 1
•Disconnectthemains/supplycable.
•Remove the system uppercover.
•DischargethecapacitorsinM10 andM11withS10(D7)(refertoFig.1).
•Wait5minutes;thenremovetheleft,rightand frontcovers.

Comply with the information given in this section, before opening the system.
Never work with the system open if the batteries are still con-
nected and the capacitor is charged. If the batteries are con-
nected, the complete system is powered on!
The capacitors in M10 and M11 may still be charged even if the
system is switched OFF and the line voltage cable is
disconnected.
Life-threatening electric shock hazard exists.
The capacitors in M10 and M11 must be considered charged until
the protective measures listed in this section have been per-
formed.

If the voltage measured between CAPPOS and CAPNEG is 0V, the
measurement device could be defective or the wires between the
CAPPOS and CAPNEG test points on the capacitor bank could be
damaged. In this case, proceed as follows:

- MeasurethevoltageonthecapacitorsinM11 and check thatthevoltagelevelis<2V
DC.Ifnot,dischargethecapacitorswithR103,seeFig.5.
Fig. 5
Verify that U11 has not blown. If U11 was blown the capacitor in
M11 will not be discharged with S10. The capacitor in M11 must
then be discharged as stated below.
If the charging/discharging does not function, the power conver-
sion unit M10 and M11 must be considered “charged”.
In this case, use the Service Instructions to guide you in trouble-
shooting.
Use caution when performing measurements at the capacitors in
M10 and M11.
Use only the specified measurement devices (350 V DC).
