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/C410/C700/C900
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/C410/C700.
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.
• 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.
• Power supply wiring must be twisted and have a low voltage drop.
• About 5 to 6 seconds are required as preparation time for contact output
every time the instrument is turned on. Use a delay relay when the output
line, is used for an external interlock circuit.
• This instrument is not furnished with a power supply switch or fuses.
Therefore, if a fuse or power supply switch is required, install close to the
instrument.
- Fuse type: Time-lag fuse
- Recommended fuse rating: Rated voltage 250 V Rated current: 1 A
• For an instrument with 24 V power supply, supply power from a SELV
circuit.
