*1. Do not use the output from an inverter as the power supply. Refer to Safety Precautions for All Timers for details on your OMRON website.
*2. With DC ratings, single-phase full-wave rectified power sources may be used.
*3. Only the H3Y-2-B Series include 12 VDC models.
*4. Use the Timer within 90% to 110% of the rated supply voltage (95% to 110% for 12 VDC) when using it continuously under an ambient
operating temperature of 50°C.
*5. Set the reset voltage as follows to ensure proper resetting.
100 to 120 VAC: 10 VAC max.
200 to 230 VAC: 20 VAC max.
100 to 110 VDC: 10 VDC max.
*6. Refer to Safety Precautions for All Timers on your OMRON website when combining the Timer with an AC 2-wire proximity sensor.
*7. A diode to prevent reverse voltages is provided only on models with a DC power supply.
