2.3 Obligations of the manufacturers of complete systems
 Tasks for system development, installation and commissioning of electric systems
may only be performed by trained and experienced staff, see Chapter 2.2 Staff
qualifications.
 The manufacturer of the complete system must ensure that no defective or faulty
control units are used. In case of failure or malfunctions, the control unit must be
replaced immediately.
 The manufacturer of the complete system must ensure that the circuity and
programming of the control unit do not lead to a safety-relevant malfunction of the
complete system in case of a failure or malfunction.
 The manufacturer of the complete system is responsible for the correct
connection of all the peripherals (such as cable profiles, plugs, crimps, correct
selection/connection of sensors/actuators).
 The control unit may not be opened.
 No changes and/or repairs may be performed on the control unit.
 If the control unit falls down, it may no longer be used and must be returned to
MRS to be checked.
 The manufacturer of the complete system must inform the end customer about all
potential dangers.
The manufacturer must also take the following aspects into consideration
when using the control unit:
 Control units with wiring suggestions provided by MRS do not constitute a
systematic responsibility for complete systems.
 Safe operation cannot be guaranteed for control units used as prototypes or
samples in the complete system.
 Faulty circuitry and programming of the control unit may lead to unforeseen
signals to the outputs of the control unit.
 Faulty programming or parameter setting of the control unit may lead to dangers
during operation of the complete system.
 It must be ensured when the control unit is released that the supply of the electric
system, of the final stages and of the external sensor supply are shut down jointly.
 Control units without factory-made software programmed more than 500 times
may not be used in complete systems any longer.
