*1. Do not use an inverter output as the power supply. Refer to your OMRON website for details.
*2. Refer to your OMRON website when using the Timer together with a 2-wire AC proximity sensor.
*3. This is longer than the minimum time for H3CR-A/H3CR-F. Be careful when using an instantaneous contact for the self-
holding circuit.
