Connection Of Power Cables - Mitsubishi Electric MELSEC iQ-F FX5U User Manual

Connection of power cables

Power cable connection of the I/O modules
The power must be supplied to the FX5-CEX/D, and FX5-C32ET/D.
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 and FX5-C32ET/DSS do not have power connectors. Supply the power to them using input connectors.
Input module (extension connector type)
FX5-CNV-IF
Use the following 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 and FX5-C32ET/DSS do not have power connectors and the power is supplied from using input connectors.
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.
