Combining the individual components
Chronological order of 24 V supply
and mains voltage
● Route lines of sufficient size to reduce load-dependent voltage drops.
● For looping through the control voltage, observe the maximum current
carrying capacity of the connection points. The maximum current carry‐
ing capacity limits the number of devices to which the control voltage
can be looped through.
A Number of devices is limited to 2 components with a current
consumption of ≤ 5 A / component
B Number of devices is limited to 3 components with a current
consumption of ≤ 3.3 A / component
C Third-party component (e.g., PLC, valve, etc.)
1) Connection to central ground point (e.g., PE earth-circuit con‐
nector)
Fig. 4-14: Installing the 24 V supply
If you use several 24 V power supply units:
● Output voltages of the 24 V power supply units must be with‐
in the permitted voltage range
● Interconnect reference conductors 0 V of the individual 24 V
power supply units with low impedance
● Always switch 24 V power supply units on and off synchro‐
nously
Before mains voltage or DC bus voltage is applied to the components, they
have to be supplied by the 24 V supply.
