(2) Set communication baud rate (the inverter parameter “f800”) to 9600, 19200 or 38400bps

(programmed by default setting at the factory).

(3) Turn off the input power to the inverter, wait until finishing discharge (See the inverter’s manual for

detail), and insure that the charge led on the inverter is no longer lit.

(4) Connect the cable delivered with the keypad between the communication connector of Remote

Keypad and that of the inverter. At this time, be careful not to apply excessive force to the

connectors.

(See the instruction manual of the inverter for connection to the communication port of the inverter.)

(5) After wiring, fix the wires on the surface of the wall in the panel board and so on.

(6) Turn on the inverter, and Remote Keypad starts-up automatically showing a lit panel in the display

window.

(7) Using in “COPY MODE”, check that the “COPY MODE” led is lit.

(8) In order to change from “REMOTE KEYPAD MODE” to the “COPY MODE”, turn off the power of

inverter and insure that the Remote Keypad is also turned off. Then, turn on the power of the

inverter (Remote Keypad) while holding down the [ENT] key of Remote Keypad.
