Overview
The life of the inverter and the converter unit is influenced by the
surrounding air temperature.
The surrounding air temperature should be as low as possible within the
permissible range. This must be noted especially when the inverter is
installed in an enclosure.
Incorrect wiring may lead to damage of the inverter and the converter unit.
The control signal lines must be kept fully away from the main circuit lines
to protect them from noise.
The converter unit built-in EMC filter can reduce the noise.
Must be within the permissible power supply specifications of the converter
unit.
Must be selected carefully since an inrush current flows in the converter
unit 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 and the converter unit.
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 and the converter unit may be damaged if you do not
use a reactor.
Select a reactor according to the applied motor capacity.
Suppresses the noise radiated from the power supply side of the converter
unit.
Suppresses the power supply harmonics significantly. Install these options
as required.
When FR-HC2 is used, FR-CC2 is not required.
Allows the inverter to provide the optimal regenerative braking capability.
Install these options as required.
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
and the converter unit. The noise filter is effective in the range from about
0.5 MHz to 5 MHz.
Connect a squirrel-cage induction motor.
