Connect mains to the terminals at the right lower side of the cabinet. Please refer to the schematics shipped with your sat-nms ACU2-ODU for detailed pin description. As standard, you can connect 3ph mains for load circuit (short break) and 1ph for control circuit (UPS). If you only have 3ph short break available, it is possible to us e short break mains for control circuit as well. Just connect L1 and N of 3ph mains to UPS input U-L1 and U-N in this case.
In this cabinet, terminals of type ‘XTV’ of phoenix contact are used for mains connection. To connect a cable, just remove isolation (attach a wire end ferrule if necessary) and put it into the terminal, take care that the actuator is pressed down before doing this. As soon as the cable is deep enough in the terminal, the clamp of the terminal closes automatically. To remove a cable, just press down the actuator until it snaps, and pull the cable out.
