Thanks Richard and Marty.
My Durst just has a cable run from the lamp to the 2 pin plug. Maybe the previous owner changed the plug to fit the timer connection.
To avoid cutting and rewiring I need something like this:

I am in Berlin next week so may have a look for an adapter there.
However, it makes sense to cut the 2 pin plug off and fit a new IEC plug as recommended by Richard. I am more likely to use the stopclock for all my printing than return to the Baeuerle.
