Instantaneous
overcurrent protection
Stops at approx. 250% of rated output current
tions
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
Undervoltage protection Stops when main-circuit DC voltage is approximately
200 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 fin overheating Detects at 110°C ± 10°C
Grounding protection Protection at rated output current level
Charge indicator (RUN
indicator)
Lit when the main circuit DC voltage is approximately
50 V or less.
