(1) To improve the unit's resistance to signal interference, install modules for low-voltage
signals toward the left of the unit, and modules for power signals toward the right.
Also, separate the wires of each.
(2) Allow at least 70mm clearance between the units and between other control
equipment to allow access for maintenance and ventilation.
(3) When installing the unit near high-voltage or high-power equipment, leave at least
200mm clearance, or shield the unit with a steel plate.
(4) Refer to the following table for the size of I/O cables.

However, for common lines, use a thicker size which takes account of the current
capacity. Also, for cables outside the panel, the use of cable of at least 1.25mm
recommended to keep the impedance low.
(5) The M3.5 screw is used as a terminal screw. Use an appropriate crimp-type terminal
with a width of 7mm (0.28 in) or less for the M3.5 screw.
