All connectors are removable. 90-253VAC L 22-120VDC EARTH N Caution All units are equipped with 2 terminal blocks to dispatch the auxiliary power supply. One block for input and one block to make a bridge to the next unit by mean of a flat cable supplied in standard. To avoid electrical chocks, all these connectors must always be filled. If only one of the 2 terminal blocks is used (without giving supply to the next unit), the second block must be filled by the 3 points empty cap delivered in standard. Cable-layer should connect power supply wires and jumpers on both ends of the line of interfaces.
