Because they are the outer rails depending upon which way the train is crossing and will become a direct short.

 

This becomes painfully obvious even with the relay when all 4 switches are set to diverge and it is used as a crossover and a train rolls in from the "flip" side.

douger:

Are you asking about non-derail or powering the diamond?

If you are asking about non-derail then you need only a short piece of track in front of the turnout with an isolated rail and a wire connected from the rail to the proper wire of the switch motor you want to throw (see https://ogrforum.com/t...02#37611054196794702)

If you are asking about powering the diamond you need to solder wires to the diamond rails, connect to a DZ1008 relay which is connected to the appropriate switch motor. Ross has diagrams for this.
