func-
tions
Instantaneous
overcurrent
protection
Stops at approx. 250% of rated output current
Overload
protection
Stops in 1 min at approximately 150% of rated output current
Overvoltage
protection
Stops when main-circuit DC voltage is approximately 820 V
Undervoltage
protection
Stops when main-circuit DC voltage is approximately 400 V
Momentary power
interruption
compensation
(selection)
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.
Cooling fin
overheating
Detects at 110°C ± 10°C
Grounding
protection
Protection at overcurrent detection level
Charge indicator
(RUN indicator)
Lit when the main circuit DC voltage is approximately 50 V or less.

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.
