Spanish term or phrase: llave de enclavamiento
The text is talking about occupational safety when working on and around wind turbines. This section is about working on the medium- and low-voltage cubicles. There are actually several terms that have got me foxed, but I'll ask them in separate questions.

"Para dejar sin tensión una instalación, en primer lugar, abrir todas las fuentes de tensión y comprobar la ausencia de la misma. Después se llevará a cabo la puesta a tierra y cortocircuitará. A continuación utilizará la *llave de enclavamiento* y pondrá la señalización. Por último colocará la llave en su lugar correspondiente de la cota de trafo."

I've found 'llave de enclavamiento' as 'lock-grip wrench' (Routledge), but I think here it must be talking about something like the locking/interlocking key/lever, on the signal box. I'm not sure whether both 'llaves' are referring to the same thing.
