2. Mounting
Mounting Cautions :
(1) Use this instrument within the following ambient temperature and ambient humidity.
z Allowable ambient temperature: 0 to 50°C
z Allowable ambient humidity: 45 to 85% RH
(2) Avoid the following when selecting the mounting location.
z Rapid changes in ambient temperature which may cause condensations.
z Corrosive or inflammable gases.
z Direct vibration or shock to the mainframe.
z Water, oil, chemicals, vapour or steam splashes.
z Excessive induction noise, static electricity, magnetic fields or noise.
z Direct air flow from an air conditioner.
z Exposure to direct sunlight.
z Excessive heat accumulation.

Mounting Procedure
Mounting Cautions :
(1) Use this instrument within the following ambient temperature and ambient humidity.
z Allowable ambient temperature: 0 to 50°C
z Allowable ambient humidity: 45 to 85% RH
(2) Avoid the following when selecting the mounting location.
z Rapid changes in ambient temperature which may cause condensations.
z Corrosive or inflammable gases.
z Direct vibration or shock to the mainframe.
z Water, oil, chemicals, vapour or steam splashes.
z Excessive induction noise, static electricity, magnetic fields or noise.
z Direct air flow from an air conditioner.
z Exposure to direct sunlight.
z Excessive heat accumulation.
Mounting Procedures
(1) Prepare the panel cutout as specified in 2.2 Dimensions.
(2) Insert the instrument through the panel cutout.
(3) Insert the mounting bracket into the mounting groove
of the instrument. (As Fig.1)
(4) Pull till chick sounds to the direction shown by the arrow.
(As Fig.2)
(5) The other mounting bracket should be installed the same
way described in 3.To 4.
3. WIRING
Wiring Cautions :
(1) For thermocouple input, use the specified compensation wire.
(2) For RTD input, use leads with low resistance and having no resistance differences among the 3 leads.
(3) Conduct input signal wiring away from instrument power, electric equipment power and load lines to avoid noise
induction.
(4) Conduct instrument power wiring so as not to be influenced by noise from the electric equipment power. If the
instrument may be affected by external noise, a noise filter should be used.
* shorten the distance between twisted power supply wire pitches. The shorter the distance between the pitches,
the more effective for noise reduction.
* Install the noise filter on the panel which is always grounded and minimize the wiring distance between the noise
filter output side and the instrument power terminals.
* Do not install fuses and/or switches on the filter output signal since this may lessen filter effect.
(5) For wiring, use wires conforming to the domestic standard of each country.
(6) About 4 to 5 seconds is required as the preparation time for contact output after power on. Use the delay relay
when the output line is used for an external interlock circuit.
(7) This instrument has no power supply switch nor fuses. Therefore, install the fuse close to the instrument and the switch,
if required.
* Recommended fuse rating: Rated voltage; 250 V Rated current; 1A * Fuse type; Time-lag fuse
(8) Do not excessively tighten the terminal screws. In addition, use the solder less terminal appropriate to the screw size.
(9) To the instrument with power supply of 24V, please be sure to supply the power from SELV circuit
Terminal Configuration :
(1) All the under hookups are only for reference.
(2) For wiring, please according to the hookup label which was glued
on the plastic case of controller.
