Note
Establishing the connection for Basic Line Modules
Basic Line Modules do not contain auxiliary power modules. The 24 V DC voltage supply is
provided by connecting the 2-phase cable included in the Basic Line Module to the auxiliary
power module of the adjacent cabinet unit.
Hazardous electrical voltage caused by incorrect voltage assignment
When establishing connections to the auxiliary power supply system, you must ensure that
you do not interchange the power supplies! Errors or carelessness can result in serious
injury or damage to the components or system.
