be used here.
The specifications for short-circuit protection (fuses, circuit
breakers or miniature circuit breakers) are available for the device
connections of the main circuit and of the auxiliary circuit.
In order to enable a holistic assessment of the protection of device
connections, the manufacturer is obliged to provide all relevant
information on short-circuit and overcurrent protection.
For example, if device connections for control supply voltage,
supply voltage or digital inputs and digital outputs are not
connected to self-limiting current or energy sources, you will find
the relevant information in the Equipment Manual or Technical
Data Sheet.
