2.3 Mounting procedures 

 

C100 

 

When the controllers are mounted on 
panel with 1 to 5 mm in thickness

 

Since the mounting brackets are already 
installed  on  the  controller,  insert  the 
controller  into  the  panel  front  without 
removal of the brackets. 

 

 

When the controllers are mounted on 
panel with 5 to 9 mm in thickness

 

Remove  the  mounting  brackets  from  the 
controller with a slotted screwdriver.   
Engage each mounting bracket with holes 
marked  with 5-9 on the housing and then 
insert the controller into the panel from the 
panel front.

 

 

 

 

C400/410/700/900 

1. 

Prepare 

the 

panel 

cutout 

as 

specified in 2.2 Dimensions

2. 

Insert  the  instrument  through  the 
panel cutout. 

3. 

Insert  an  upper  mounting  bracket 
along  the  bracket  insertion  groove 
from  the  back,  and  then  engage  a 
projection  at  the  bracket  end  with  a 
recess  at  the  groove  front  and  also 
insert metal fitting legs into slots. 

4. 

Tighten  a  bracket  setscrew  from  the  rear  of  the  bracket  with  Phillips 
screwdriver. Do not overtighten the bracket setscrew. 

5. 

The other  mounting  bracket  should  be  installed  the  same  way  described 
in 3. and 4

 

C900  is  used  in  the  above  figures  for  explanation,  but  the  same 
mounting procedures also apply to C400/410/700. 

 

3. WIRING 

 
 
 
 
 
 

 

3.1 Wiring Cautions 

  For thermocouple input, use the appropriate compensation wire. 

  For RTD input, use low resistance lead wire with no difference in resistance 

between the three lead wires. 

  To avoid noise induction, keep input signal wire away from instrument 

power line, load lines and power lines of other electric equipment. 

  Signal connected to Voltage input and Current input shall be low voltage 

defined as “SELV” circuit per IEC 60950-1. 

  If there is electrical noise in the vicinity of the instrument that could affect 

operation, use a noise filter. 
-  Shorten  the  distance  between  the  twisted  power  supply  wire  pitches  to 

achieve the most effective noise reduction. 

-  Always  install  the  noise  filter  on  a  grounded  panel.  Minimize  the  wiring 

distance  between  the  noise  filter  output  and  the  instrument  power  supply 
terminals to achieve the most effective noise reduction. 

- Do not connect fuses or switches to the noise filter output wiring as this will 

reduce the effectiveness of the noise filter. 

 
 
 
 
 

 

  Allow approximately 5 to 6 seconds for contact output when the instrument 

is turned on. Use a delay relay when the output line is used for an external 
interlock circuit. 

  Power supply wiring must be twisted and have a low voltage drop. 

  This instrument with 24 V power supply is not provided with an overcurrent 

protection device. For safety install an overcurrent protection device (such 
as fuse) with adequate breaking capacity close to the instrument. 
-  Fuse  type:  Time-lag  fuse  (Approved  fuse  according  IEC60127-2  and/or 
 

UL248-14) 

- Fuse rating: Rated current: 0.5 A 

  For an instrument with 24 V power supply input, supply power from “SELV”   

circuit defined as IEC 60950-1. 

  A suitable power supply should be considered in end-use equipment.  The 

power  supply  must  be  in  compliance  with  a  limited-energy  circuits 
(maximum available current of 8 A). 

 

 

 

Mounting bracket

Hole for 5 to 9 mm

Hole for 1 to 5 mm

 

 

 

Mounting bracket 

   

 

To prevent electric shock or instrument failure, do not turn on 
the  power  until  all  wiring  is  completed.  Make  sure  that  the 
wiring is correct before applying power to the instrument.
