· CAUTION
For safety’s sake and to maintain the proper functioning of the
product, you should not draw it out from its case.
If it is necessary to draw out the instrument, contact our office in
your neighborhood
(1) Machine the mounting hole by referring to the panel cutout
drawings in Section 2-3.
(2) Applicable thickness of the mounting panel is from 1.0 to 4.0
mm
(3) This product is provided with pawls which fix it when it is
pressed straight into the front panel.

(1) Wiring should be carried out according to the drawings in "2-5.
Terminal arrangement." Confirm that there is no wrong
connection
(2) Use crimp terminals which meet the M3.5 screw and are less than
7 mm in width.
(3) For thermocouple input, select a compensation wire suitable for
the particular type of thermocouple.
(4) For R.T.D. input, each lead should be less than 5
Ÿ
in resistance
and three leads should have the same resistance.
(5) The input signal line should be conducted safely apart from high
voltage power lines.
(6) Shield wiring (one-point grounding) works effectively against
static induction noise.
(7) Twisting the input signal wire at equal intervals is effective
against electromagnetic induction noise.
(8) For power lines, use wire or cable which is 1 mm
2
in size or
thicker and is equivalent to or higher in grade than 600V vinyl
insulated wire
(9) Earth wiring should be carried out with less than 100
Ÿ
ground
resistance by using wire which is 2 mm 2 or thicker.
(10) Noise filter: If the instrument appears to be easily affected by
power supply noise, use a noise filter for preventing malfunction.
The noise filter should be mounted on the grounded panel and
make wiring between the controller and the power terminal as
short as possible.
·
CAUTION
If the product is a thermocouple input specification, the cold junction is
exposed at the terminal No. 6 (for SR82) or the terminal No. 8
(for SR83/SR84)
Do not touch here with a screwdriver or anything when writing.

WARNING
• The product must be disconnected from its power source
during wiring operation so as to prevent electric shock.
• The protective conductor (earth) terminal must be grounded
prior to use. Otherwise, electric shock may result.
• Do not touch the wired terminals and charged devices while
power is on.
