• Wire the power cords of the PS-A, I/O
devices, and power supply devices sepa-
rately.
• To improve noise immunity, it is recom-
mended to attach a ferrite core to the power
cord.
• Isolate the main circuit (high voltage, large
current) line, I/O signal lines, and power
cord, and do not bind or group them
together.
• To prevent damage from lightning, connect
a lightning surge absorber.
• Ground the lightning surge
absorber (E1) and the PS-A
(E2) separately.
• Select a lightning surge
absorber which will not exceed
the allowable circuit voltage,
even when the voltage rises to
the maximum.
