CAUTION
D
Do not connect phase-advancing capacitors or LC/RC noise filters to the output cir-
cuits.
The Inverter can be damaged or internal parts burnt if these devices are connected.
NO TAG
D
Do not connect electromagnetic switches or contactors to the output circuits.
If a load is connected while the Inverter is operating, surge current will cause the overcurrent
protection circuit inside the Inverter to operate.

D
Disconnect the load (machine, device) from the motor before autotuning.
The motor may turn, possibly resulting in injury or damage to equipment. Also, motor
constants cannot be correctly set with the motor attached to a load.
