When using a single programmable controller, a 10A breaker
or an external fuse are recommended for wiring protection.

(f) Note on using the 24 VDC output of the A1S62PN power
supply module.
If the 24 VDC output capacity is insufficient for one power
supply module, supply 24 VDC from the external 24 VDC
power supply as shown below:

(g) 100 VAC, 200 VAC and 24 VDC wires should be twisted as
dense as possible. Connect the modules with the shortest
distance.
Also, to reduce the voltage drop to the minimum, use the
thickest wires possible (maximum 2mm
(h) Do not bind 100VAC and 24VDC wires together with main
circuit (high tension and large current) wires or I/O signal line
(including common line) nor place them near each other.
Provide 100mm (3.94 inches) clearance between the wires if
possible.
