another block.
Two power connectors of the FX
2NC-EX, FX2NC-16EX-T and FX2NC/FX3UC Series special extension
blocks are connected in parallel inside the block, and there is no distinction between the power inlet side
and the power outlet side. Either connector can be used for wiring. At shipment from the factory, a resin
cover is attached to the lower connector. Use the upper connector first. Remove the resin cover from the
lower connector only when performing crossover wiring for another block.

2NC-EX-DS and FX2NC-16EX-T-DS do not have a power connector, and receive power from
the input connector. It is not necessary to remove the resin cover.)
