The input circuit of the device must correspond to one of the connection types listed. Select
the suitable connection type for the purpose.
You can find connection examples in the chapter "Connecting".
Local power supply conditions
Before connecting the SENTRON PAC3200, you must ensure that the local power supply
conditions agree with the specifications on the type plate.
The short code of the connection type must be entered in the device settings at startup. You
can find the instructions for parameterizing the connection type in the chapter "Starting up".
