接线方法及注意事项 ndl2 dhc3l dzslsq 4

1. The signal input and the reset input switch or circuit should be as close as possible to the terminal of the timer.Keep the input line as short as possible.
2. Dhc3l-a is the input type of AC voltage of the accumulator signal, and AC/DC110 ~ 240V voltage can be input, but the reset signal of this type is shown in Figure (3). Only contact signals can be input.
3. The reset signal should not be switched on for a long time to avoid wasting the internal battery.
4. Contact input should be reliable.
▲ This product has built-in lithium battery, do not pressure deformation or overheating above 100℃, so as not to cause lithium battery rupture or burn out.
