Danger
Reference
Prohibited
-Do not touch any inverter's terminal when it is energized even if the motor
is standstill, or you could get a shock.
-Do not operate switches with a wet hand or not put a wet cloth on the
inverter, or you could get a shock.
-Do not get near the alarm-stopped motor when the system is in retry
mode, or you could get an injury.
Take safety measures, for example, attaching a cover to the motor, to
protect persons against accidents when the motor unexpectedly restarts.
-Don't set the motor constant 3 (exciting inductance:) as 1/2 or less
value of default setting value. If the motor constant 3 (exciting
inductance :) is set as extremely small value, the stole prevention
function
will incorrect-operate and will raise output frequency.
-Don't set the stole prevention level() as extremely small value.
When the stole prevention level() is set as motor no-load current
or value lower than it, the stole prevention function always operates. And
if it is judged as regeneration mode, frequency will be raised.
Please do not set the stole prevention level() to 30% or less in
the usual usage.

Mandatory
-Do not turn on the power before attaching the front cover. When the
inverter is installed in a cabinet with the inverter's front panel detached,
always close the door of the cabinet before turning on the power.
Turning on the power with the cover or the door left opened could lead to
an electric shock.
-Turn off the operation signal before resetting the inverter after trouble, or
the motor unexpectedly restarts, causing injury to persons.

Mandatory
-Operate the motor always within the allowable operation range. (Refer to
the motor’s instruction manual for the allowable operation range.)
Failure to do so could cause injury to persons.

When selecting the sequence that automatically restarts the motor after
recovery from a momentary power failure (Applicable to inverters)
Warning
Reference
Mandatory
-Do not get near the motor or the machine.
The motor and the machine unexpectedly restart after recovery from a
momentary power failure.
-Stick caution labels to the inverter, the motor and the machine, to prevent
accidents due to an unexpected restart of them after recovery from a
momentary power failure.
