Note: 1. There may be the influence of reflection depending on the transmission speed and/or
transmission distance. If this reflection hinders communication, provide a terminal
resistor. If the PU connector is used to make a connection, use a distributor as a
terminal resistor cannot be fitted. Connect the terminal resistor only to the inverter
remotest from the computer.(Terminal resistor: 100 Ω)
2. Make connections in accordance with the instruction manual of the computer used.
Fully check the terminal numbers of the computer as they differ between models.
