Control Voltage Supply
Note: The control sections are supplied via the terminal connectors
24V and 0V at the power section (24V supply).
Note: The isolated inputs/outputs at X31 and X32 are not supplied
via the connections of the 24V supply of the power section. A
separate voltage supply is required for these inputs/outputs.
Note: Overvoltage of more than 33 V has to be discharged by
means of the appropriate electrical equipment of the machine
or installation.
This equipment includes:
• 24V power supply units that reduce incoming overvoltages
to the allowed value.
• Overvoltage limiters at the control cabinet input that limit
existing 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 overvoltages by
inductive or capacitive coupling.
