port 1
(1) Used to connect the keypad. The power to the keypad will be supplied from the inverter
through this connector.
(2) Also can be used to connect a computer, programmable controller, etc by RS-485
communication, after removing the keypad. (On terminating resistor, refer to “2.2.8
Operating slide switches”).

• Pins 1, 2, 7, and 8 are assigned as power supply source for the keypad. When
connecting this RJ-45 connector to other devices, do not use these pins.

* This terminal is used on the models with the destination codes -GA.
* SW6 is shared between RS-485 communications and CAN bus communications.
If both communications are used at the same time and the necessity of the terminating
resistor for each communication network is different (for example in the CAN bus is
located at either end of the network, but in the RS-485 network is located in the middle),
turn SW6 “OFF” and use an external terminating resistor where needed.
