Note
Information on the dimensioning of fuses in higher
-level system circuits
A fuse that is designed for a typical trip
ping current of 6.3
A is integrated in the power supply
unit of the IPC. The pulse currents during startup are also taken into account by the
"time lag"
type. In the case of a fault, this fuse ensures the correct disconnection of the device from the
power
supply system.
It is recommended that a fuse of at least 6.3
A, plus the power demand of the other devices
that are also supplied via this c
ircuit, be used for protection of the higher-level power supply
circuit. The tripping characteristic of the higher
-level protection must take into account the
starting currents of both the IPC and the other devices.
