• The output data is retained when "1 or 11" is set in Pr.495 Remote output selection.
NOTE
• Inrush current equal to or higher than the 24 V external power supply specification may flow at power-ON. Confirm that the
power supply and other devices are not affected by the inrush current and the voltage drop caused by it. Depending on the
power supply, the overcurrent protection may be activated to disable the power supply. Select the power supply and
capacity carefully.
• When the wiring length between the external power supply and the inverter is long, the voltage often drops. Select the
appropriate wiring size and length to keep the voltage in the rated input voltage range.
• In a serial connection of several inverters, the current increases when it flows through the inverter wiring near the power
supply. The increase of the current causes voltage to drop further. When connecting different inverters to different power
supplies, use the inverters after confirming that the input voltage of each inverter is within the rated input voltage range.
Depending on the power supply, the overcurrent protection may be activated to disable the power supply. Select the power
supply and capacity carefully.
• When an external 24 V power supply is used, "E.SAF" may appear if the power supply start-up time is too long (less than 1.5
V/s).
• Do not touch the option board while the 24 V external power is supplied (when conducted). Doing so may cause an electric
shock or burn.
