Auto Direct is my first source when I buy my automation products and have had no issues in the past with any of their product, however this safety relay really threw me for a loop when wiring and testing. Given it's a German device and the drop sheet is written in multiple languages, I get it that there's only so much they can include in the instructions. However one of the most important things needed to get this to work is barely mentioned and is not shown in any diagrams. There are 2 switches that need to be switched (depending on your application) in order for the relay to work. The said switches live under a cover on the top of the relay where the power and relay status LED's are located. There is no mention anywhere on how to access these switches. I was ready to throw the relay in the trash until I noticed the 4 grooves in the cover so you can pry the cover off with a small screwdriver. Very frustrating. Would I buy it again? Why yes, now that I know where the stinking switches live.
