Note
Information on the dimensioning of the fuses in the higher-level plant circuits
A fuse, which is designed for a tripping current of typical 6.3
A, is integrated in the power
supply of the IPC. Pulse current are also take
n into consideration by the "time lag" type. In
the case of fault, this fuse ensure the correct separation of the device from the power supply.
It is recommended to use a fuse of at least 6.3 A for the protection of the higher
-level power
n addition to the power requirement of the additional devices that are also
supplied through this circuit. The tripping characteristic of the higher
-level protection must
hereby take into consideration the starting currents of the IPC and those of the othe

The total output of the +5 V and +3.3 V voltage must be ≤ 100 W.
The total current of the +12 V voltage must be ≤ 25 A.
The inrush current of a plug-in module is:
● ≤ 210 A for 1.65 ms
8.4.5 Technical specifications of the telescopic rails
