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 
should therefore use a surge absorber.
• Surge waveform
[
±(1.2×50) µs uni-polar full wave voltage]
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:
12 to 48 V AC/DC
100 to 240 V AC/DC
1,000 V
6,000 V
