Termination of direct burial wire is done as you would terminate any other set of wires. However, direct burial does not mean you can direct bury the terminations. The wire must be brought into a building by an approved method; or the wire must be brought into a box designed for burial, with the box accessible from the surface of the ground; or the wire must be brought into a piece of equipment that is partially buried and designed for that purpose.
In no case should the wire reach a depth of less than the minimum required depth for the installation without being protected by conduit. And in no case should the wire enter a building without conduit unless installing UF cable is allowed without conduit in the installation.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.
