Safety Precautions
Refer to Safety Precautions for All Timers.
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
supplies with a high frequency component (such as inverter power
supplies) 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
selector switches with a flat-blade screwdriver as desired.
Be sure to turn the power off before changing the time specification.
Changing the time range while the timer is in operation may result in
a malfunction.

Connections
Connecting the Operating Power Supply
If using an AC power supply, connect it between terminals 2 and 7. If
using a DC power supply, connect the positive line to terminal 7 and
the negative line to terminal 2. An AC power supply can be
connected without considering polarity, but the DC power supply
lines must be connected as specified.
Other Precautions
• A DC power supply must have 50% or less ripple and the average
• A P3G-08 Socket can be used instead of a US-08 Socket to reduce
voltage must be within the rated supply voltage specification.
