Power Source Connection
Because the AC-operated version is a capacitive load, the solid-
state relay to be used must be rated at a dielectric strength two times
as that of the timer to switch the power source of the timer.
The H3M contains a capacitor-drop power circuit. Use a sinusoidal
power supply with a commercial frequency. Do not use power sup-
plies with a high frequency component (such as inverter power sup-
plies) for Timers with 100 to 240-VAC specifications. Using these
power supplies can damage internal circuits.
How to Change the Time Range
The H3M is provided with two time range selector switches. One is
on the lower right side A of the front panel and the other on the lower
left side. Change the positional combination of the time range selec-
tor switches with a flat-blade screwdriver as desired.
ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.

Caution
Be sure to turn the power off before changing the time specifi-
cation. Changing the time range while the timer is in operation
may result in a malfunction.
