INSTALLATION AND WIRING
2.2 Installation Procedure
1) Remove the inverter front cover.
2) Mount the hex-head screw for option
mounting into the inverter screw hole (on
earth plate). (size 5.5mm, tightening
torque 0.56N⋅m to 0.75N⋅m)
3) Securely fit the connector of the plug-in
option to the inverter connector along the
guides.
4) Securely fix the both right and left sides
of the plug-in option to the inverter with
the accessory mounting screws. If the
screw holes do not line-up, the connector
may not have been plugged snugly.
Check for loose plugging.
REMARKS
After removing two screws on the right and left
places, remove the plug-in option.
(The plug-in option is easily removed if the
control circuit terminal block is removed before.)

" " (option alarm) is displayed.
