The life of the inverter is influenced by the ambient temperature.
The ambient temperature should be as low as possible within the
permissible range.
Incorrect wiring may lead to damage of the inverter. The control signal
lines must be kept fully away from the main circuit lines to protect them
from noise.
The built-in EMC filter can reduce the noise.
In this inverter, a DC reactor and common mode choke are built in to
suppress harmonics and to improve the power factor.
Must be within the permissible power supply specifications of the inverter.
Must be selected carefully since an inrush current flows in the inverter at
power ON.
Install this to ensure safety.
Do not use this to start and stop the inverter. Doing so will shorten the life
of the inverter.
Install this to suppress harmonics and to improve the power factor.
An AC reactor (FR-HAL) (option) is required when installing the inverter
near a large power supply system (1000 kVA or more). Under such
condition, the inverter may be damaged if you do not use a reactor.
Select a reactor according to the applied motor capacity.
Suppresses the power supply harmonics significantly. Install this as
required.
Provides a large braking capability. Install this as required.
, BU )
  Allows the inverter to provide the optimal regenerative braking capability.
Install this as required.
, MT-BR5 )
 
A USB (Ver. 1.1) cable connects the inverter with a personal computer.
A USB memory device enables parameter copies and the trace function.
Install this to reduce the electromagnetic noise generated from the
inverter. The noise filter is effective in the range from about 0.5 MHz to 5
MHz.
A wire should be wound four turns at maximum.
Connect a squirrel-cage induction motor.
Connect this for an application where a PM motor is driven by the load
even while the inverter power is OFF. Do not open or close the contactor
while the inverter is running (outputting).
When PM sensorless vector control is selected, a PM motor can be
driven.
