2. MOUNTING
2.1 Mounting Cautions
(1) This instrument is intended to be used under the following environmental conditions.
(IEC61010-1) [OVERVOLTAGE CATEGORY II, POLLUTION DEGREE 2]
(2) Use this instrument within the following environment conditions:
Allowable ambient temperature: 0 to 40 C
Allowable ambient humidity: 10 to 90 %RH
(Absolute humidity: MAX.W.C 29.3 g/m3dry air at 101.3kPa)
(3) Avoid the following conditions when selecting the mounting location:
Rapid changes in ambient temperature which may cause condensation.
Corrosive or inflammable gases.
Direct vibration or shock to the mainframe.
Water, oil, chemicals, vapor or steam splashes.
Excessive dust, salt or iron particles.
Excessive induction noise, static electricity, magnetic fields or noise.
Direct air flow from an air conditioner.
Exposure to direct sunlight.
Excessive heat accumulation.
(4) Mount this instrument in the panel considering the following conditions:
Provide adequate ventilation space so that heat does not build up.
Do not mount this instrument directly above equipment that generates large amount of heat (heaters,
transformers, semi-conductor functional devices, large-wattage resistors.)
If the ambient temperature rises above 40 C, cool this instrument with a forced air fan, cooler, etc.
Cooled air should not blow directly on this instrument.
In order to improve safety and the immunity to withstand noise, mount this instrument as far away as
possible from high voltage equipment, power lines, and rotating machinery.
High voltage equipment: Do not mount within the same panel.
Power lines: Separate at least 200 mm.
Rotating machinery: Separate as far as possible.
(5) If this instrument is permanently connected to equipment, it is important to include a switch or
circuit-breaker into the installation. This should be in close proximity to the equipment and within
easy reach of the operator. It should be marked as the disconnecting device for the equipment.
To prevent electric shock or instrument failure, always turn off the power before
mounting or removing the instrument.

2.3 Procedures of Mounting and Removing
Mounting procedures
1. Prepare the panel cutout as specified in
2.2 Dimensions.
2. Insert the AF110 through the panel cutout.
3. Insert the mounting bracket into the mounting from
the rear of the AF110 (Fig. 2.1).
4. Push the mounting bracket forward until the frame is
firmly secured to the panel
(Fig. 2.2).
When using the mounting screws
Removal procedures
1. Turn the power OFF.
2. Remove the wiring.
3. Pull the mounting bracket () while releasing the
hooks upward or downward () to remove the
mounting bracket (Fig. 2.3).
4. Pull out the instrument from the mounting cutout
while holding the front panel frame
of this instrument (Fig. 2.4).
It is possible to pull the AF110 out with the front
panel frame while releasing the hooks upward or
downward.
The front of the instrument conforms to IP66 [Specify when ordering] when mounted on the
panel. For effective Waterproof/Dustproof, the rubber packing must be securely placed
between instrument and panel without any gap. If rubber packing is damaged, please contact
RKC sales office or the agent.
Only turn one full
revolution after the
screw touches the
panel.

3. WIRING
3.1 Wiring Cautions
To avoid noise induction, keep communication 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.

Shorten distance between pitches
Noise
filter OUT
About 6 seconds are required as preparation time for output every time 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.
For an instrument with 24 V power supply, supply power from a SELV circuit.
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).
This instrument is not provided with a power supply switch or fuse. Therefore, a fuse and power
supply switch are required, install close to the instrument.
Recommended fuse rating:Rated current:0.5 A
Fuse type: Time-lag fuse
(Approved fuse according IEC 60127-2 and/or UL 248-14 and min.
interrupting rating 8 A at 24 V DC)
All wiring must be in accordance with local codes and regulations.
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.

When connecting or disconnecting the connectors, do not force it too far to right and left or up and
down, but move it on the straight. Otherwise, the connector pins may be bent, causing instrument
failure.
When disconnecting a connector, hold it by the connector itself. Disconnecting connectors by
yanking on their cables can cause breakdowns.
To prevent malfunction, never touch the contact section of a connector with bare hands or with
hands soiled with oil or the like.
