The connection of 24V
DC
to X11 is required for the power supply of the control unit.
ATTENTION!
Device damage due to overload!
If the 24 V
DC
power supply is looped to multiple devices over the terminal, the terminal may be damaged by a current that is
too high.
▪ Make sure that the current over the terminal does not exceed the value 15A (UL: 10A).
