REMARKS
*1. Make connection in accordance with the instruction manual of the computer to be
used with. Fully check the terminal numbers of the computer since they change with
the model.
*2. The inverters may be affected by reflection depending on the transmission speed or
transmission distance. If this reflection hinders communication, provide a termination
resistor. When the RS-485 connector is used for connection, a termination resistor
cannot be fitted, so use a distributor. Connect the termination resistor to only the
inverter remotest from the computer. (Termination resistor: 100 )
