WARNING
The SR1, 3, 4 series digital controllers are control instruments
designed for industrial use to control temperature, humidity and
other physical values. Avoid using it for control of devices upon
which human life is dependant. When used, adequate and
effective safety measures must be taken. No warranty is valid in
the case of an accident arising from the use of this product
without having taken such safety measures.
Be sure to turn off power while performing wiring. Failure to
do so could result in electric shock. After wiring, do not touch
terminal elements or other charged parts. Failure to do so could
result in electric shock.
Never remove the controller from its case. Doing so could
result in electric shock.
CAUTION
Be sure to follow the instruction manual when operating this
device. If the SR1,3,4 series is used in a manner not specified
in this manual, the protection provided by the SR1,3,4 series
may be impaired.
Do not use this instrument other than specified.
Using the instrument other than specified may result in trouble
with the instrument or may cause a fire.
Voltage/current of a load to be connected to the output terminal
should be within a rated range.
Do not blo
ck the draft hole or allow dust and the like to stick to
the case of the instrument for heat discharge.
A rise in temperature or insulation failure may result in a
reduction of the life of the product and/or problems with it or
may cause a fire.
Do not operate keys on the front panel with a hard or sharply
pointed object. Operate the keys only by softly touching them
by your fingertips.
When cleaning the instrument, wipe it gently with a dry cloth.

overheating protection device and the like.
The alert mark on the plate affixed to the instrument:
On the terminal nameplate affixed to the case of this
instrument, the alert mark is printed. This is to warn you
of the risk of electric shock which may result if the charger is
touched while being energized.
As a means to turn the power off, a switch or a breaker should
be installed in the external power circuit to be connected to the
power terminal of the instrument.
As a means to turn the power off, a switch or a breaker (which
confirms with IEC 60947) should be installed in the external
power circuit to be connected to the power terminal of the
instrument.
Since the instrument does not have a built-in fuse, do not forget
to install a fuse in the power circuit to be connected to the
power terminal.
Fuse rating/characteristics: 250V AC 0.5A/medium lagged or
lagged type.
Use a fuse which conforms with IEC 60127.
