« Le câblage frontal demande trop d'espace »

Since we’re not exclusively a controller manufacturer, we need the complete width from the smallest to the largest cross-section. On the high current terminal blocks, we connect up to 160 A with stranded wires and single conductors.

We’re familiar with the different variants, but we avoid them ourselves as far as possible, since they make the connection situation worse for the electricians. So, when planning the switchgear combination, we always use the normal terminal block to calculate the terminal block space and really only use double-deck terminal blocks in exceptional situations.

I think that’s basically a good solution. However, with the larger input modules, I find the sealing problematic, since it takes up too much space for terminal blocks with front-entry wiring. From my point of view, side-entry wiring would be a significant improvement, since it’s easier to seal the line entry from the front. For this reason, we run the supply cables to a screw-clamp terminal block so we don’t lose too much space in the depth dimension. Besides that, we don’t use screw-clamp terminal blocks.

From not needing a second product, as we clearly only want pluggable connection.

That’s true! For expansion, we use the second slot and simply leave the existing jumper plugged in. That’s great, because it lets us expand easily even while the system is running. If we had to remove the inserted jumper, it wouldn’t be as easy.

Almost exactly the way you show in your catalogs! Our labeling spans three lines. On the bottom line we number the terminal blocks, on the middle one we indicate the X number and on the top one the load. We now have almost ten smart printers in use. We use a separate printer for each medium so we don’t have to adjust it.

We use a printer for labeling the terminal blocks, for example. Another example is the labeling of individual markers; we even use those to mark third-party products. We print the silver labels for door installations on an additional Smart Printer. In my opinion, there’s no better way to clearly label terminal blocks. You’ve provided a fantastic solution, and your marking system is also the reason we switched to WAGO.

I also like the fact that, with the Smart Printer, we can check whether the calculated terminal block space is really sufficient within a few seconds. To do this, we just leave the marking strip off before assembly. Then whoever’s in charge can just hold the strip up to the control cabinet and immediately see whether the planning was correct. In the past, sometimes we’d place the terminal blocks, and after 80 percent of the work was done, we’d realize that the available space was insufficient. And this verification mechanism involves no extra effort for us, since we’d have to print out the marking strip anyway.

We use the Excel import function, but only to a very limited extent, since we often don’t get the data from the planning stage at all. When we’re the ones drawing the diagram, that’s all set and works just fine. But with most of the circuit diagrams we get from outside sources, we have to copy it manually in the workshop.
