Replacing the AVT combination module

High voltages on the AVT combination module and the precision 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.
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.
Removing the AVT combination module
1. Follow "the five safety rules (Page 15)".
2. Detach the cable connections
3. Remove the four fixing screws
Installing the AVT combination module
1. Use the screws
