Precautions for Safe Use
8E5@C Digital Temperature Controllers User’s Manual (H174)
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 unex-
pected events. Use the product within the specifications.
•The product is designed for indoor use only. Do not use or store the product outdoors or in any of the
following locations.
Locations directly subject to heat radiated from heating equipment.
Locations subject to splashing liquid or oil atmosphere.
Locations subject to direct sunlight.
Locations subject to dust or corrosive gas (in particular, sulfide gas and ammonia gas).
Locations subject to intense temperature change.
Locations subject to icing and condensation.
Locations subject to vibration and large shocks.
•Use and store the Digital Controller within the rated ambient temperature and humidity.
Gang-mounting two or more Digital Controllers, or mounting Digital Controllers above each other may
cause heat to build up inside the Digital 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 Controllers.
•To allow heat to escape, do not block the area around the product. Do not block the ventilation holes
on the product.
•Be sure to wire properly with correct polarity of terminals.
•Use the specified size of crimped terminals (M3, width of 5.8 mm or less) for wiring. To connect bare
wires to the terminal block, use copper braided or solid wires with a gage of AWG24 to AWG18
(equal to a cross-sectional area of 0.205 to 0.8231 mm2). (The stripping length is 6 to 8 mm.) Up to
two wires of the same size and type, or two crimped terminals can be inserted into a single terminal.
•Do not wire the terminals that are not used.
•To avoid inductive noise, keep the wiring for the Digital Controller's terminal block away from power
cables that carry high voltages or large currents. Also, do not wire power lines together with or
parallel to Digital 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 Digital Controller.
Allow as much space as possible between the Digital Controller and devices that generate powerful
high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge.
•Use this product within the rated load and power supply.
•Make sure that the rated voltage is attained within 2 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.
•Make sure that the Digital 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.
•When executing self-tuning, turn ON power for the load (e.g., heater) at the same time as or before
supplying power to the Digital Controller. If power is turned ON for the Digital Controller before turning
ON power for the load, self-tuning will not be performed properly and optimum control will not be
achieved.

9
Precautions for Safe Use
E5@C Digital Temperature Controllers User’s Manual (H174)
•A switch or circuit breaker should be provided close to Digital Controller. The switch or circuit breaker
should be within easy reach of the operator, and must be marked as a disconnecting means for
Digital Controller.
•Wipe off any dirt from the Digital Controller with a soft dry cloth. Never use thinners, benzine, alcohol,
or any cleaners that contain these or other organic solvents. Deformation or discoloration may occur.
•Design the system (e.g., control panel) considering the 2 seconds of delay in setting the Digital
Controller’s output after the power supply is turned ON.
•The output will turn OFF when you move to the Initial Setting Level. Take this into consideration when
performing control.
•The number of non-volatile memory write operations is limited. Therefore, use RAM write mode when
frequently overwriting data, e.g., through communications.
•Use suitable tools when taking the Digital Controller apart for disposal. Sharp parts inside the Digital
Controller may cause injury.
•Do not connect cables to both the front-panel Setup Tool port and the top-panel Setup Tool port at the
same time. The Digital Controller may be damaged or may malfunction.
•Do not exceed the communications distance that is given in the specifications. Use the specified
communications cable.
•Do not turn the power supply to the Digital Controller ON or OFF while the USB-Serial Conversion
Cable is connected. The Digital Controller may malfunction.

Installation Precautions
10 E5@C Digital Temperature Controllers User’s Manual (H174)
Installation Precautions
zService Life
Use the Digital Controller within the following temperature and humidity ranges:
Temperature: −10 to 55°C (with no icing or condensation), Humidity: 25% to 85%
If the Digital Controller is installed inside a control board, the ambient temperature must be kept to
under 55°C, including the temperature around the Controller.
The service life of electronic devices like Digital Controllers is determined not only by the number of
times the relay is switched but also by the service life of internal electronic components. Component
service life is affected by the ambient temperature: the higher the temperature, the shorter the
service life and, the lower the temperature, the longer the service life. Therefore, the service life can
be extended by lowering the temperature of the Digital Controller.
When two or more Digital Controllers are mounted horizontally close to each other or vertically next
to one another, the internal temperature will increase due to heat radiated by the Digital Controllers
and the service life will decrease. In such a case, use forced cooling by fans or other means of air
ventilation to cool down the Digital Controllers. When providing forced cooling, however, be careful
not to cool down the terminals sections alone to avoid measurement errors.
zAmbient Noise
To avoid inductive noise, keep the wiring for the Digital Controller's terminal block wiring away from
power cables carrying high voltages or large currents. Also, do not wire power lines together with or
parallel to Digital 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 compo-
nent). 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 Digital Controller.
Allow as much space as possible between the Digital Controller and devices that generate powerful
high frequencies (high-frequency welders, high-frequency sewing machines, etc.) or surge.
zEnsuring Measurement Accuracy
When extending or connecting the thermocouple lead wire, be sure to use compensating wires that
match the thermocouple types.
When extending or connecting the lead wire of the platinum resistance thermometer, be sure to use
wires that have low resistance and keep the resistance of the three lead wires the same.
Mount the Digital Controller so that it is horizontally level.
If the measurement accuracy is low, check to see if input shift has been set correctly.

Installation Precautions
E5@C Digital Temperature Controllers User’s Manual (H174)
zWaterproofing
The degree of protection is as shown below. Sections without any specification on their degree of
protection or those with IP@0 are not waterproof.
Front panel: IP66
Rear case: IP20, Terminal section: IP00
When waterproofing is required, insert the Waterproof Packing on the backside of the front panel.
Keep the Port Cover on the front-panel Setup Tool port of the E5EC/E5AC securely closed. The
degree of protection when the Waterproof Packing is used is IP66. To maintain an IP66 degree of
protection, the Waterproof Packing and the Port Cover for the front-panel Setup Tool port must be
periodically replaced because they may deteriorate, shrink, or harden depending on the operating
environment. The replacement period will vary with the operating environment. Check the required
period in the actual application. Use 3 years or sooner as a guideline. If the Waterproof Packing and
Port Cover are not periodically replaced, waterproof performance may not be maintained. If a
waterproof structure is not required, then the Waterproof Packing does not need to be installed.

Precautions for Operation
12 E5@C Digital Temperature Controllers User’s Manual (H174)
Precautions for Operation
•It takes approximately two seconds for the outputs to turn ON from after the power supply is turned
ON. Due consideration must be given to this time when incorporating Digital Controllers into a control
panel or similar device.
•Make sure that the Digital 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.
•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 Controller. If power is turned ON for the Digital Controller before turning
ON power for the load, self-tuning will not be performed properly and optimum control will not be
achieved. When starting operation after the Digital Controller has warmed up, turn OFF the power
and then turn it ON again at the same time as turning ON power for the load. (Instead of turning the
Digital Controller OFF and ON again, switching from STOP Mode to RUN Mode can also be used.)
•Avoid using the Digital Controller in places near a radio, television set, or wireless installing. The
Digital Controller may cause radio disturbance for these devices.
