PRECAUTIONS IN USING THE QM4H
1. Avoid locations subject to flammable
or corrosive gases, excessive dust, oil,
vibrations, or excessive shocks.
2. Since the main-unit is made of
polycarbonate resin, avoid contact with or
use in environments containing methyl
alcohol, benzene, thinners, and other
organic solvents; and ammonia, caustic
sodas, and other alkaline substances.
3. Power supply superimposed surge
protector
Although a surge protector will withstand
standard-waveform voltage with the
values in the next table, anything above
this will destroy the internal circuit. You
or corrosive gases, excessive dust, oil,
vibrations, or excessive shocks.

3. Power supply superimposed surge
protector
Although a surge protector will withstand
standard-waveform voltage with the
values in the next table, anything above
this will destroy the internal circuit. You
should therefore use a surge absorber.

4. In order to maintain the characteristics,
do not remove the timer case.
5. When installing the panel, use the
supplied AQM4812 main-unit
mounting frame. Note that the AT8-DA4
is also available for sale separately.
6. If you change the operating voltage,
be sure not to allow leak current into
the timer.

7. Avoid leaving the unit powered
continuously. Leaving the unit
powered up with output set to ON
continuously for a long period of time
(about 1 month or more) will wear out
the electronic components. If you will
be keeping it powered continuously,
combine with a relay to create the
circuit shown below:
