NOTE
• When mounting/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.
• Caution must be applied to mounting screws falling off when removing and mounting the plug-in option.
• The priorities of vector control compatible plug-in options are defined as follows: FR-A8AL > FR-A8APS > FR-A8APR
> FR-A8AP. The vector control compatible plug-in options with lower priority do not function.
• Two or more of the same options cannot be connected. When multiple options are mounted, priority is given to option
connectors 1, 2 and 3 on the inverter in this order, and options having a lower priority do not function.
• When the inverter cannot recognize the option unit due to improper installation, etc., or when a fault occurs in the
option or encoder, the protective function (E.1 to E.3 or E.OP1 to E.OP3) is activated and the inverter cannot be
operated. A different indication will appear according to the mounted position (option connector 1 to 3).
