Warning!
The connection diagram shown is merely an example which must be adapted
in the individual case depending on the application!
Note!
In extremely EMC-stressed environments, burners without fan motor or burners
equipped with fan control via auxiliary contactor should use an AGK25 to produce a
burden on terminal 3. If not observed, the burner is not reliably started up
