Note 1. The power supply capacity is the capacity for the Inverter's rated output. It will vary depending
on the impedance at the input power supply. (This is due to fluctuations in the power factor.
The power factor can be improved by inserting an AC reactor.) There will also be variations in
the ratio between the rated current of the motor that is used and the rated output current of the
Inverter.
Note 2. The heat radiation is the electric power consumed in the Inverter at the Inverter's rated output.
Note 3. The 5.5- and 7.5-kW Inverters are closed wall-mounting models (NEMA1/IP20) as a stan-
dard, but they can be converted to panel-mounting (IP00) by removing the top and bottom
covers.

Protection by electronic thermal
Stops at approx. 250% of rated output current
Stops in 1 min at approximately 150% of rated output current
Stops when main-circuit DC voltage is approximately 820 V
Stops when main-circuit DC voltage is approximately 400 V
Stops for 15 ms or more. By setting the Inverter to momentary
power interruption mode, operation can be continued if power is
restored within approximately 0.5 s.
Detects at 110°C ± 10°C
Protection at overcurrent detection level
Lit when the main circuit DC voltage is approximately 50 V or less.
