Control Voltage
Project planning 24V supply
For the 24V supply, take the data on the dimensioning of the pow‐
er supply unit into account (see index entry "24V supply → Notes
on project planning").

Overvoltage
Overvoltage greater than 33 V has to be discharged by means of
the appropriate electrical equipment of the machine or installation.
This includes:
● 24V power supply units that reduce incoming overvoltage to
the allowed value.
● Overvoltage limiters at the control cabinet input that limit ex‐
isting overvoltage to the allowed value. This, too, applies to
long 24V lines that have been run in parallel to power cables
and mains cables and can absorb overvoltage by inductive
or capacitive coupling.
Mains Voltage
The single-phase mains connection is not allowed!
