Chronological order of 24 V supply and mains voltage
Before mains voltage or DC bus voltage is applied to the components, they
have to be supplied by the 24 V supply.
Looping through the control voltage
You are only allowed to loop through the control voltage between the compo-
nents, if the sum of current consumptions ΣI
smaller than the current carrying capacity of the connection point.

Output voltages of the 24 V power supply units have to be within the
allowed voltage range
Interconnect 0 V reference conductors of the individual 24 V power supply
units with low impedance
Always switch 24V power supply units on and off synchronously
