The life of the inverter 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. The control signal lines
must be kept fully away from the main circuit lines to protect them from
noise.
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 (500 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.
Install this to suppress harmonics and to improve the power factor.
Select a reactor according to the applied motor capacity.
When using a DC reactor, remove the jumper across terminals P/+ and P1
before connecting a DC reactor to the inverter.
Install this to reduce the electromagnetic noise generated from the inverter.
Install this to reduce the radio noise.
Suppresses the power supply harmonics significantly. Install this as
*1
required.
Provides a large braking capability. Install this as required.
Allows the inverter to provide the optimal regenerative braking capability.
Install this as required.
Connect between the inverter and a personal computer with a USB (ver.
1.1) cable.
Increases the braking capability. (0.4K or higher)
Install this to reduce the electromagnetic noise generated from the inverter.
The noise filter is effective in the range from about 0.5 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).
An IPM motor cannot be driven by the commercial power supply.
