to prevent electric shock, fire or damage to instrument
and equipment.
This instrument must be used in accordance with the
specifications to prevent fire or damage to instrument
and equipment.
This instrument is not intended for use in locations
subject to flammable or explosive gases.
Do not touch high-voltage connections such as power
supply terminals, etc. to avoid electric shock.

2. MOUNTING
2.1 Installation Environment
(1) This instrument is intended to be used under the following
environmental conditions. (IEC61010-1)
[OVERVOLTAGE CATEGORY II, POLLUTION DEGREE 2]
(2) Avoid the following when selecting the mounting location.
Ambient temperature of less than 0 °C or more than 50 °C.
Ambient humidity of less than 45 % or more than 85 % RH.
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.
2.3 Mounting Procedures
1. Prepare the panel cutout as specified in
2. Insert the instrument through the panel cutout.
3. Insert the mounting bracket into the mounting groove of
the instrument. (Fig.1)
Push the mounting bracket forward with a blade screwdriver
4.
until the bracket is firmly secured to the panel. (Fig.2)
5. The other mounting bracket should be installed the same way described in 3 and 4.
When the instrument is individually mounted, always secure with two mounting brackets either top and bottom or right and left.
In addition, the mounting assembly also include two screws which can be used with the brackets to secure the instrument to the panel.
See Fig. 3.
The waterproof/dustproof option on the front of the instrument conforms to IP66 when mounted on the panel. For effective
waterproof/dustproof, the gasket must be securely placed between instrument and panel without any gap. If gasket is damaged,
contact your nearest RKC agent or sales office.
3. WIRING
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.
-
About four 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.
Power supply wiring must be twisted and have a low voltage drop.
For an instrument with 24V power supply, supply power from a SELV circuit.
This instrument is not furnished with a power supply switch or fuse. Therefore, if a fuse or power supply switch is required, install close to
the instrument. [Recommended fuse rating: Rated voltage 250 V, Rated current 1 A
For the current input specification, a resistor of 250Ω (±0.02 % ±10 ppm, 0.25 W or more) must be connected between the input terminals.
If this resistor is installed, close vertical mounting is not possible. This resistor must be provided by the customer.
The input and output terminals for the voltage pulse output are not isolated. Always use an isolating type SSR. If the grounded type sensor
is used, do not ground output wiring. Do not connect any output wires to the terminals with any other output wires.
3.1 Restrictions on Wiring
Always use recommended solderless terminal lugs or equal.
M3 × 6 (With 5.8 × 5.8 square washer)
Screw size:
Recommended tightening torque: 0.4 N･m
Applicable wire: Solid/twisted wire of 2 mm
Recommended dimension:
Recommended solderless terminals: Circular terminal with isolation
(M3 screw, width 5.5 mm, hole diameter 3.2 mm)
IMR01D01-E1
CAUTION
This is a Class A instrument. In a domestic environment,
this instrument may cause radio interference, in which case
the user may be required to take adequate measures.
This instrument is protected from electric shock by
reinforced insulation. Provide reinforced insulation between
the wire for the input signal and the wires for instrument
power supply, source of power and loads.
This instrument is designed for installation in an enclosed
instrumentation panel. All high-voltage connections such
as power supply terminals must be enclosed in the
instrumentation panel to avoid electric shock by operating
personnel.
All precautions described in this manual should be taken to
avoid damage to the instrument or equipment.
All wiring must be in accordance with local codes and
regulations.
To prevent instrument damage or failure, protect the power
line and the input/output lines from high currents with a
protection device such as fuse, circuit breaker, etc.
Prevent metal fragments or lead wire scraps from falling
inside instrument case to avoid electric shock, fire or
malfunction.

Tighten each terminal screw to the specified torque found
in the manual to avoid electric shock, fire or malfunction.
For proper operation of this instrument, provide adequate
ventilation for heat dispensation.
Do not connect wires to unused terminals as this will
interfere with proper operation of the instrument.
Turn off the power supply before cleaning the instrument.
Do not use a volatile solvent such as paint thinner to clean
the instrument. Deformation or discoloration will occur. Use
a soft, dry cloth to remove stains from the instrument.
To avoid damage to instrument display, do not rub with an
abrasive material or push front panel with a hard object.

Always connect external wires starting from the
lower terminals (No.1 to 6). Disconnect the wires
starting from the upper terminals (No.7 to 12).
When multiple instruments are vertically closely
mounted, do not connect two or more solderless
terminal lugs to one terminal.
If multiple instruments are vertically
closely mounted, it is necessary to
bend the terminal lugs when they are
connected to the lower terminals.
