5.5 Connecting Methods for CPU Module and Extension Devices
Connection of power cables
Power cable connection of the CPU module, extension power supply module and I/O
modules
The power must be supplied to the FX5UC CPU module, FX5-C1PS-5V, FX5-C  EX/D, and FX5-C32ET/D.
Use the power cable for CPU modules to supply the power to the FX5UC CPU module and FX5-C1PS-5V.
To supply the power to FX5-C
 EX/D and FX5-C32ET/D, use two power connectors (upper and lower) on each module for
crossover wiring.
FX5-C
 EX/DS(-TS) and FX5-C32ET/DS  do not have power connectors. Supply the power to them using input connectors
or input terminal blocks.
The following products are provided with power cables.
• Wiring FX5-C  EX/D or FX5-C32ET/D to a subsequent stage
Since the two power connectors on each module of FX5-C  EX/D and FX5-C32ET/D are connected in parallel inside the
module, they have no difference and can be either an inlet port or outlet port for supplying the power. Thus, cables can be
connected to either of the connectors.
However, since the lower connector is covered with a resin cover at shipment from the factory, use the upper connector
preferentially. Remove the resin cover only when crossover wiring to a subsequent module is performed.
(FX5-C
 EX/DS(-TS) and FX5-C32ET/DS  do not have power connectors and the power is supplied from using input
connectors or input terminal blocks. Thus, removing the resin cover is not required.)
Precautions
To perform crossover wiring, supply the power from the preceding module to the subsequent module. The power cannot be
supplied from the subsequent module to the preceding module.

Resin cover
Since the lower connector is covered with a resin cover at
shipment from the factory, use the upper connector
preferentially. Remove the resin cover only when crossover
wiring to a subsequent extension module is performed.
