WARNING
 Prevent dropping objects into the AC drive during drive running.
Failure to comply may result in damage to the AC drive.
 Do not start or stop the AC drive by turning on or off the
contactor. Failure to comply may result in equipment damage.

injury or equipment damage.
 Do not repair or maintain the AC drive at power-on. Failure to
comply will result in electric shock.
 Repair or maintain the AC drive at least ten minutes after the
AC drive is powered off. This allows for the residual voltage in
the capacitor to discharge to a safe value. Failure to comply will
result in personal injury.
 Ensure that the AC drive is disconnected from all power supplies
before starting the repair or maintenance work.
 All the pluggable components must be plugged or removed only
after power-off.
 Set and check the parameters again after the AC drive is
replaced.
WARNING
 The rotating motor generally feeds back power to the AC drive.
As a result, the AC drive is still energized even if the motor
stops, and the power supply is cut off. Thus ensure that the AC
drive is completely disconnected from the motor before starting
the repair or maintenance work.

transient and steady-state leakage current to ground that may be generated at startup
and during running of the AC drive. You can select a specialized RCD with the function
of suppressing high harmonics or a general-purpose RCD with relatively large residual
current.
