Selecting the breaker / magnetic contactor
Check the model name of the inverter and the converter unit you purchased. Appropriate peripheral devices must be selected
according to the capacity.
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 built-in EMC filter of the converter unit 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.
Suppresses the noise radiated from the power supply side of the converter
unit.
Connect between the inverter and a personal computer with a USB (ver.
1.1) cable.
Use a USB memory device to copy parameter settings or use 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 to 5 MHz.
Connect a squirrel-cage induction motor.
