Install the duct for wiring if necessary. But, if the distance between upper part or

In case of installing on the upper PLC, the height of wiring duct should be less
than 80mm for good ventilation.
In case of installing on the lower PLC, consider minimum radius of the cable.
In case the equipment is installed in front of the PLC (inside the door) to avoid
the effect of radiant noise or the heat, separate it from the PLC of distance more than
