NOTE
• When the junction connector is installed to the plug-in option, the option is fixed with the hooks of the connector. The
junction connector cannot be removed from the plug-in option.
• When removing the front cover for plug-in option from the inverter, note that the recessed neck screw cannot be removed
from the front cover for plug-in option.
• When the body screws of the inverter are removed to install the hexagon spacers (in Step 4 on
14), make sure that the control circuit board does not fall off due to the weight of cables.
• When installing/removing the plug-in option, hold the sides of the option. Do not press on the parts on the option circuit
board. Stress applied to the parts by pressing, etc. may cause a failure.
• Be careful not to drop mounting screws during the installation or removal of the plug-in option.
• When the inverter cannot recognize the option due to improper installation or any other reason, the protective function (E.1)
is activated and the inverter cannot be operated.
