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 and store the Digital Temperature Controller 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
Digital 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 specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring. Use wires with a gage of
AWG24 to AWG14 (equal to cross-sectional areas of 0.205 to 2.081 mm
2
). (The stripping length is 5
to 6 mm.)
6) Do not wire the terminals which are not used.
7) To avoid inductive noise, keep the wiring for the Digital Temperature Controller's terminal block away
from power cables carry high voltages or large currents. Also, do not wire power lines together with or
parallel to Digital Temperature Controller 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 temperature controller.
Allow as much space as possible between the Digital Temperature Controller 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 the power ON.
10) Make sure the controller has 30 minutes or more for warm up.
11) When using self-tuning, turn ON power for the load (e.g., heater) at the same time as or before
supplying power to the Digital Temperature Controller. If power is turned ON for the Digital Temper-
ature Controller before turning ON power for the load, self-tuning will not be performed properly and
optimum control will not be achieved.
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) Always turn OFF the power supply before pulling out the interior of the product, and never touch nor
apply shock to the terminals or electronic components. When inserting the interior of the product, do
not allow the electronic components to touch the case.
14) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.
