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

Connection of power cables

Power cable connection of the CPU module and I/O modules
The power must be supplied to the FX5UC CPU module, FX5-C32EX/D, and FX5-C32ET/D. Use
the power cable for CPU modules to supply the power to the FX5UC CPU module.
To supply the power to FX5-C32EX/D and FX5-C32ET/D, use two power connectors (upper and lower) on each module
for crossover wiring.
FX5-C32EX/DS and FX5-C32ET/DSS do not have power connectors. Supply the power to them using input connectors.

Classification Application
A Power cable for CPU modules
B Power cable for FX5-C32EX/D and FX5-C32ET/D
C Power crossover cable for FX5-C32EX/D and FX5-C32ET/D
• Wiring FX5-C32EX/D or FX5-C32ET/D to a subsequent stage
Since the two power connectors on each module of FX5-C32EX/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-C32EX/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.
