The modules are supplied in a packaging together with a packing slip with instal-
lation instructions. Please read the complete packing slip carefully before unpack-
ing the module.
NOTICE

IEC 61340-5-1.
NOTICE
Fuse does not trip in the event of an error
Provide external fuses for the 24 V area of each module. The power supply unit
must be able to supply four times the nominal current of the external fuse, to en-

Switch off the I/O supply voltage at the relevant module. The communications
power that is supplied at the bus coupler/controller is still available.
For a bus coupler/controller, this means:
