The appliances are easy to connect and to disconnect. To connect two appliances next to each other (side by side), there is a connecting element on the underside of one of the appliances that holds the two appliances firmly together and can be easily attached by hand. The included connecting cable, which is also easy to fit, allows both raclettes to be operated simultaneously with one mains cable. However, two or three appliances can also be connected in series one behind the other. Here too, the cables can be easily connected by hand and without tools in no time at all.
