(e) Taking rated current or inrush current into consideration when
wiring the power supply, be sure to connect a breaker or an
external fuse that have proper blown and detection.
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

).
