Figure 2-3-13 Connection example of PLC terminal (when analog signal is input from PLC)
1) Set SW7 at CM.
2) With this connection, the power is supplied from the PLC power supply to the external thermal O/L relay.
So, OH2 trip is activated by PLC power-off with the inverter turned on.
3) To prevent inverter trip with OH2 when the PLC power being turned off, do not select the THR terminal function and
use the inverter electronic thermal O/L relay.
5) Connection to PLC (When analog signal is input from PLC)
When SW7 is set at P24, poly switch (F1) activates a current limit to
turn the power off.
