The AVT combination modules are part of the actual value acquisition module. The installation
location is described in the layout diagram.
WARNING
High voltages
The AVT combination modules and measuring resistors are at hazardous voltage levels.
Touching actual value acquisition components, particularly measuring resistors or LEM
current transformers, can result in death, serious injury, or material damage.
● Do not touch AVT combination modules, LEM current transformers, or measuring resistors
under any circumstances.
● Do not make any changes to the design of the actual value acquisition.
