(f) Note on using the 24 VDC output of the A1S62PN power supply
module.
Do not connect multiple power supply modules to one

module in parallel. The power supply modules may be
heated, resulting in a fire or failure.
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 V AC, 200 V AC and 24 V DC 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 wires (including common
line) nor place them near each other. Provide 100mm (3.94 inch)
clearance between the wires if possible.
