Safety Precautions
Refer to Safety Precautions for All Temperature Controllers.
!CAUTION
* A class 2 power supply is one tested and certified by UL as having
the current and voltage of the secondary output restricted to specific
levels.
Precautions for Safe Use
Be sure to observe the following precautions to prevent malfunction
or adverse affects on the performance or functionality of the product.
Not doing so may occasionally result in faulty operation.
1. This product is specifically designed for indoor use only.
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 and store the product within the rated ambient temperature
and humidity.
Gang-mounting two or more Temperature Controllers, or
mounting Temperature Controllers above each other may cause
heat to build up inside the Temperature Controllers, which will
shorten their service life. In such a case, use forced cooling by
fans or other means of air ventilation to cool down the
Temperature Controllers.
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 the specified size of crimp terminals for wiring (M3.5, width of
7.2 mm or less). For open-wired connections use stranded or solid
copper wires with a gauge of AWG24 to AWG14 (equal to a cross-
sectional area of 0.205 to 2.081 mm
2
). (The stripping length is 5 to
6 mm.) Up to two wires of the same size and type or two crimp
terminals can be connected to one terminal. Do not connect more
than two wires or more than two crimp terminals to the same
terminal.
6. Do not wire the terminals that are not used.
7. To avoid inductive noise, keep the wiring for the product’s terminal
block away from power cables carry high voltages or large
currents. Also, do not wire power lines together with or parallel to
product wiring. Using shielded cables and using separate conduits
or ducts is recommended.
Attach a surge suppressor or noise filter to peripheral devices that
generate noise (in particular, motors, transformers, solenoids,
magnetic coils, or other equipment that have an inductance
component).
When a noise filter is used at the power supply, first check the
voltage or current, and attach the noise filter as close as possible
to the product.
Allow as much space as possible between the product and
devices that generate powerful high frequencies (high-frequency
welders, high-frequency sewing machines, etc.) or surge.
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 Temperature 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 must be provided close to the product.
The switch or circuit breaker must 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 the system (e.g., control panel) considering the 2 seconds
of delay that the product'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.
Therefore, use RAM write mode when frequently overwriting data
during communications or other operations.
16.Always touch a grounded piece of metal before touching the
Temperature Controller to discharge static electricity from your
body.
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.
Do not use the Temperature Controller or the USB-
Serial Conversion Cable if it is damaged. Doing so may
occasionally result in minor electric shock or fire.
Never disassemble, modify, or repair the product or
touch any of the internal parts. Minor electric shock, fire,
or malfunction may occasionally occur.
CAUTION - Risk of Fire and Electric Shock
a) More than one disconnect switch may be required to
de-energize the equipment before servicing the
product.
b) Caution: To reduce the risk of fire or electric shock, do
not interconnect the outputs of different Class 2
circuits. *
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
conditions.
Tighten the terminal screws to the rated torque of
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 product may occasionally make
control operations impossible or prevent alarm outputs,
resulting in property damage. To maintain safety in the
event of malfunction of the product, take appropriate
safety measures, such as installing a monitoring device
on a separate line.
Do not allow pieces of metal or wire cuttings to get inside
the USB-Serial Conversion Cable connector for the
Support Software. Failure to do so may occasionally
result in minor electric shock, fire, or damage to
equipment.
Do not allow dust and dirt to collect between the pins in
the connector on the USB-Serial Conversion Cable.
Failure to do so may occasionally result in fire.
