● Operating point, currents and voltages
● Log file with fault messages
● Copy of the CompactFlash card
● If possible, hard copies from the plotter or screenshots
● Mounting location
Specify the equipment identifier. You can find the item code on the component and close to
the slot.
WARNING
Danger when components are incorrectly replaced
Incorrectly replacing components can result in death, serious injury, or material damage.
● Only replace components that are described in the following sections. All other
components may only be replaced by Siemens service personnel. In this case, contact the
Service Center.
9.7.1 Replacing the AVT combination module
WARNING
Danger caused by high voltages at the AVT combination module and the precision measuring
resistors
The AVT combination modules and measuring resistors are at hazardous voltage levels.
Touching these components can result in death, severe injury and significant material
damage.
● Never touch the AVT combination modules or measuring resistors under any
circumstances.
WARNING
Danger when making changes to the design of the voltage or ground fault detection
Changes to the voltage or ground fault detection, e.g. to the measuring resistors, are
potentially lethal. This can result in substantial property damage, physical injuries and death.
● Do not change the design of the voltage or the ground fault detection.
