I did a remote on a RL140 single phase based on what others have already done here,
If you look in older message for 2020 you should find this thread. It based on the fact that the RL has an automatic position and with a $20 box item from amazon you can open and close this circuit that start and stop your RL. This #20 box item close and open the RL circuit based on its own connection to a standard 120v socket. If your festool remote can close and open a standard 120v outlet, you are good to go.
