Note Crimp-type terminals must be used for terminal connections, and the screws
must be tightened securely. Use M3 screws and tighten them to a torque of
0.5 N S m.

To minimize output wiring noise, ground the output signal line to the output de-
vice.
3-3-4 Output Wiring Considerations
When wiring outputs, apply the following points to avoid noise interference and
optimize Analog Output Unit performance.
• Use shielded twisted-pair cable for external connections.
• Route output cables separately from the AC cable, and do not run the Unit’s
cables near a main circuit cable, high voltage cable, or a non-PC load cable.
• If there is noise interference from power lines (if, for example, the power supply
is shared with electrical welding devices or electrical discharge machines, or if
there is a high-frequency generation source nearby) install a noise filter at the
power supply output area.
• When the power supply to the PC is turned on or off, momentary voltage or
current may be output from the output terminal.
