If the motors have an earth connection in their flex, then they are class I. (generally if its metal cased and not marked as class II then its best to assume class I)
So long as the earth of the circuit feeding the motors is included in the rooms EQ bonding, then you don't need anything else. The protective conductor feeding the motor itself will serve dual purpose as both earth and bonding connection.
Its likely its an induction motor, and will have a high inrush current. Hence the need for a higher rating of fuse than nominal[1] 10A that the
2.1kW rating would suggest.It might be worth tracking down the manual for the motor if you can to see if it actually specifies that the motor *must* have additional protection from a 16A device, or whether it is just highlighting that protection with a 13A fuse in a SFCU etc unlikely to hack it due to the high inrush.
If it specifies that it must be protected at 16A device, then it will make your task a little more interesting if you want to feed it from a spur on a 32A ring circuit. You would then probably have to use a MCB, or a HRC cartridge fuse in a suitable enclosure instead.
[1] Induction motors also tend to have non unity power factors, which can increase the actual maximum current drawn.
