Precautions for Safe Use

Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse affects on the
performance and functions of the product. Not doing so may occasionally result in unexpected events.
(1) The product is designed for indoor use only. Do not use the product outdoors or in any of the following locations.
•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 specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring. To connect bare wires to the
terminal block, use copper braided or solid wires with a rated temperature of over 70°C and a gauge of AWG24 to
AWG14 (equal to a cross-sectional area of 0.205 to 2.081 mm ). (The stripping length is 5 to 6 mm.) Up to two wires
2

of same size and type, or two crimped terminals can be inserted into a single terminal.
(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 ON the power using a switch or relay
contact. If the voltage is applied gradually, the power may not be reset or output malfunctions may occur.
(10) Make sure that the Controller has 30 minutes or more to warm up after turning ON the power before starting
actual control operations to ensure the correct temperature display.
(11) 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.
(12) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.
(13) Design system (control panel, etc) considering the 2 second of delay that the controller’s output to be set after
power ON.
(14) The output may turn OFF when shifting to certain levels. Take this into consideration when performing control.
(15) The number of non-volatile memory write operations is limited.

Warning Symbols
CAUTION
Do not touch the terminals while power is being supplied.
Doing so may occasionally result in minor injury due to electric shock.
Do not allow pieces of metal, wire clippings, or fine metallic shavings or filings from installation to enter the
product. Doing so may occasionally result in electric shock, fire, or malfunction.
Do not use the product where subject to flammable or explosive gas. Otherwise, minor injury from explosion
may occasionally occur.
Never disassemble, modify, or repair the product or touch any of the internal parts. Minor electric shock, fire,
or malfunction may occasionally occur.
If the output relays are used past their life expectancy, contact fusing or burning may occasionally occur.
Always consider the application conditions and use the output relays within their rated load and electrical life
expectancy. The life expectancy of output relays varies considerably with the output load and switching
Tighten the terminal screws to between 0.74 and 0.90 N·m. Loose screws may occasionally result in fire.

Set the parameters of the product so that they are suitable for the system being controlled. If they are not
suitable, unexpected operation may occasionally result in property damage or accidents.
A malfunction in the Temperature Controller may occasionally make control operations impossible or prevent alarm outputs, resulting in
property damage. To maintain safety in the event of malfunction of the Temperature Controller, take appropriate safety measures, such
as installing a monitoring device on a separate line.
