Two power connectors of each input extension
block are connected in parallel inside the block.
Accordingly, there is no discrimination between
the entrance side and the exit side of the
power supply. Either (upper or lower)
connector can be connected.
At shipment from the factory, a resin cover is
attached to the lower connector. Connect the
upper connector first. Remove the resin cover
from the lower connector when performing
crossover wiring for the later block.
