*1 Specifi ed with the rated input voltage (100 or 200 VAC) and 100% load applied.
*2 Automatic recovery occurs after dropping. When output is interrupted, wait for 1 minute or
longer after the input is turned off, and then turn on the input for recovery.
*3 Output is cut off by an amplitude interrupting system. When output is interrupted, wait for 1
minute or longer after the input is turned off, and then turn on the input for recovery.
