Hi, do concealed fan coils in a twin split system require independent mains power?
or can you link across from the 1&2 terminals?

If being powered from a separate feed and as long as there is a local isolator to each one you will be okay.

If being fed from the condensing unit then check with the installation instructions. Separate local isolators still required.

if you look at the inside of the electrical box cover (indoor unit) it shows a 'common connection' with links across from 1 & 2 terminal numbers

normally you link from outdoor to 1st spur then out to 2nd spur- ensuring your comms s3 or no 3 is thru crimped- whats the model number ?
