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).

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.
