*1. Do not use the inverter output as a power supply.
*2. Usable up to single-phase full-wave rectification power supply.
*3. 12 V DC is for the H3Y-2 and H3Y-2-0 series only.
*4. When continuously using at an ambient operating temperature of 50°C, use at 90 to 110% of the power supply voltage (95 to 110% for 12 V DC).
*5. For reliable recovery, set to 10 V AC for 100 to 120 V AC, 20 V AC for 200 to 230 V AC, and 10 V DC or less for 100 to 110 V DC.
*6. With DC power-supply-voltage type only, the product is equipped with a counter electromotive force prevention diode.
