You only need to look at 2.7.1 in the standard to see what needs to be done.

If you are considering a fuse you may need to consider using two on
both ‘live’ and ‘neutral’ with a suitable warning. This is due to
‘EU’ mains plug connectors being un-polarised. So the mains plug can
be inserted either way around, allowing the live and neutral to the
appliance to be reversed. There is also AFAIK no set convention as to
whether sockets have the live wired to the left or right hole in the
wall socket.
Fusing in the appliance will limit the available power in the event of
a fault or disconnect the power in the event of a class I device with
‘earth fault’ from the ‘live’ side. Sounds fairly like ‘must’ to me
regardless of what the standard says! :-) Do a documented risk
assessment of the product and draw your own conclusions...

*Subject:* [PSES] Fuse in device is mandatory or not?
Consider a device connected by a plug to 230VAC by an EU plug (2 pin +
ground).
Must sucha device (EN60950-1) have an internal fuse? Or can it rely on
fuses which is a part of the house installation?
