●Warning Symbols
CAUTION
Do not touch terminals when voltage is applied.
Electric shock hazard
Do not allow metal fragments or lead wire scraps to fall inside this product. This may cause electric shock, fire
or malfunction.
Do not use this product where subject to flammable or explosive gas.
Doing so may cause explosion.
Never disassemble, repair or modify the product. This may cause electric shock, fire or
malfunction.
CAUTION - Risk of Electrical Shock
a) Devices are Open Type, Listed Process Control Equipment and must be mounted in an enclosure.
b) More than one disconnect switch may be required to de-energize the equipment before servicing.
c) Signal inputs are SELV, limited energy.
d) Caution - To reduce risk of fire or Electrical shock, Do not interconnect the outputs of different Class 2
circuits.
The life expectancy of the output relay varies considerably according to its the output relay within its rated load
and electrical life expectancy, if the output relay is used beyond its life expectancy, its contacts may become
fused or burned.
Use copper stranded or solid wire only. For terminals 1-6 use 24-14 AWG. For terminals 7-9 use 28-22 AWG.
Tightening torque: Terminals 1-6: 0.24N•m, 2 inch lbs(max), Terminals 7-9: 0.13N•m, 1.2 inch lbs(max)
Loose screws may cause malfunction.
Correctly set the settings on the temperature controller matched to the control target.If the settings are not
compatible with the control target, the product may operate in an unexpected manner, resulting in damage to
the product or an accident.
To maintain safety in the event of malfunction of the temperature controller, we recommend taking safety
measures, for example, installing an excessive temperature rise prevention alarm on a separate line. If
malfunction prevents control, this may result in a major accident.
WARNING: To reduce the risk of electric shock or fire, install in a Pollution Degree 2 environment (a
controlled environment relatively free of contaminants).

(1) Do not use this product in the following places:
• Places directly subject to heat radiated from heating equipment.
• Places subject to splashing liquid or oil atmosphere.
• Places subject to direct sunlight.
• Places subject to dust or corrosive gas (in particular, sulfide gas and
ammonia gas).
• Places subject to intense temperature change.
• Places subject to icing and condensation.
• Places subject to vibration and large shocks.
(2) Use/store within the rated temperature and humidity ranges.
Provide forced-cooling if required.
(3) To allow heat to escape, do not block the area around the product.
Do not block the ventilation holes on the product.
(4) Be sure to wire properly with correct polarity of terminals.
(5) Use AWG24 to AWG14 leads for terminal Nos. 1 to 6 and AWG28 to AWG
22 for terminal Nos. 7 to 9 (with lead cover peel back allowance of 5 or 6
mm).
(6) Do not wire the terminals which are not used.
(7) Allow as much space as possible between the controller and devices that
generate a powerful high-frequency or surge.
Separate the high-voltage or large-current power lines from other lines, and
avoid parallel or common wiring with the power lines when you are wiring to
the terminals.
(8) Use this product within the rated load and power supply.
(9) Make sure that the rated voltage is attained within two seconds of turning the
power ON.
(10) Make sure the controller has 30 minutes or more for warm up.
(11) When executing self-tuning, turn the load and the unit ON simultaneously,
or turn the load ON before you turn the controller ON.
(12) A switch or circuit breaker should be provided close to this unit.
The switch or circuit breaker should be within easy reach of the operator,
and must be marked as a disconnecting means for this unit.
(13) When you have removed the terminal block, never touch nor apply shock to
the terminals and the electronic components inside.
(14) Cleaning: Do not use paint thinner or the equivalent. Use standard grade
alcohol to clean the product.
●Installation
Individual mounting (mm)
When waterproofing is
required, be sure to mount
the controller separately.
Attach the waterproof
44.8 packing from the terminal
side and then insert the
controller to the panel.

• Insert the controller through the hole in the panel. Push
the adapter on from the rear and fasten temporarily, re-
moving any gap between the controller, panel and adap-
ter. Finally, secure two fixing screws alternately keeping
the torque to between 0.29 to 0.39 N•m.
• Make sure that the surrounding temperature does not exceed the
allowable operating temperature given in the specifications espe-
cially when two or more controllers are mounted.
• °C / °F : temperature unit
The temperature unit is displayed when
the displayed value is a temperature.
When this parameter is
set to "°C", "°c" is displayed,
and when set to "°F", "°f" is displayed.
