English to Dutch Tech/Engineering Safety

I am confused with the following terminology:

Power to lock
Power to open

FAIL SAFE: Ruststroom (open door stroomonderbreking)
FAIL SECURE: arbeidstroom (open door stroom impuls)

I am not quite sure what the difference is between this terminology.
I thought their meaning was the same, but they are used together in the same sentence, i.e. they must refer to different states.

In Dutch, do we use
"Power to Lock" = Stroom om te vergrendelen?
"Power to open" = Stroom om te openen?

This comes from a document on safety locks.

Thank you very much!!!
