Note!
The supply inputs of the bus coupler modules (main supply) and the power
supply modules are provided with internal fuses which protect them against
overvoltages.
The fuse is located in the main supply of the bus coupler module and in the
electronic module of the power supply module. If this fuse has tripped, the
main supply or the electronic module, respectively, needs to be replaced
(

0 I/O supply
The I/O supply must be secured externally using a fuse that corresponds to the maximum
current: fast fuse, or circuit breaker with a Z characteristic
1 Electronic supply
We recommend securing the electronic supply externally according to the maximum current:
fast fuse, or circuit breaker with a Z characteristic
