NOTE
• When mounting/removing the plug-in option, hold the sides of the option. Do not press on the parts on the 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.
• Only one option can be used. 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 that the option unit is mounted due to improper installation, etc., the protective
function (E.1 to E.3) is activated. A different indication will appear according to the mounted position (option connector
1 to 3).
