Note: 1. Set the must-operate voltage higher than the must-release voltage by at least 5% of the rated value.
           2. Smoothing is required for the detected DC voltage.
           3. The maximum applied voltage is 120% of the rated value.
           4. Special models enabling a rated voltage of 220 V are available. The setting range for these models is 80% to
                110%.
