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 410 V

(160 V for single-phase 200-VAC model)
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 fan
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.
