Have installed the transformer today and he made a good impression. The terminal compartment is as described by others, a little tight, but that's completely normal for such devices. 3x1,5²mm My NYM-J I can connect it well. What you should think the dimensions seen in the picture from smaller than they actually are. When unpacking I firstonce somewhat truncated, but as space had no relevance for me it was ok. It should also be noted that the transformer is warm. If he (. A small wooden box, etc. Ex) in very confined spaces is used, it should be taken care of possibly passive ventilation, or be placed outside the transformer.
