Functions of various switches are shown in Table 2.9
Before proceeding to the transfer of various switches, turn OFF the power and wait at least five minutes for
inverters of 22kW or below, or at least ten minutes for inverters of 30kW or above. Make sure that the LED
monitor and charging lamp are turned OFF. Further, make sure, using a multimeter or a similar instrument,
that the DC link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC
or below)
Otherwise an electric shock could happen.

< digital input terminals drain / source switch >
• For the digital input terminals MI1 ~ MI9, FWD, REV drain / source switches for jumper
selection.
• The factory state is SINK side .
<RS-485 Communication termination resistors switch (RS-485 Communicate Port 2
(Terminal block))>
• Set shorted cap to ON for RS-485 communication when connecting the inverter to the
terminal.
<RS-485 Communication termination resistors switch (RS-485 Communicate Port 1 (for
connection with the keypad))>
Set it to OFF (Factory state) when connecting keypad,
•Set shorted cap to ON for RS-485 communication when connecting the inverter to the
terminal.
< voltage / current output switch of terminal AFM >
Select the AFM output specification switch. Change the function parameters 00.29 when
switching short circuit jumper.
< function switch of terminal AUI >
Select the analog voltage input setting or PTC / NTC thermistor input. Change function
parameters 04.26 when switching short circuit jumper.
