Safety Precautions for All Temperature Controllers
Refer to the precautions of individual product for more specific details.
Warning
Operating Environment Precautions
1. Do not use the Temperature Controller in the following locations:
• Locations exposed to radiated heat from heating devices
• Locations subject to exposure to water or oil
The following products contain lithium batteries. Do not
disassemble, deform under pressure, heat to over
100°C, or incinerate these products. The lithium bat-
tery may ignite or explode. Applicable models: E5ZE,
E5LD, and E5LC.
• Locations subject to direct sunlight
• Locations subject to dust or corrosive gases (in particular,
sulfide gas and ammonia gas)
• Locations subject to severe changes in temperature
• Locations subject to icing or condensation
Caution
• Locations subject to excessive shock or vibration
2. Use and store the Temperature Controller within the rated
temperature or humidity range specified for each model.
When two or more Temperature Controllers are mounted hor-
izontally close to each other or vertically next to one another,
the internal temperature will increase due to the heat they
radiate and the service life of the products will decrease. In
such cases, forced cooling by fans or other means of air ven-
tilation will be required to cool down the Temperature Con-
trollers.
Do not touch any of the terminals while the power is
being supplied. Doing so may result in electric shock.
Do not allow pieces of metal or wire cuttings to get
inside the Temperature Controller. Doing so may
result in electric shock, fire, or malfunction.
Do not attempt to disassemble, repair, or modify the
Temperature Controller. Any attempt to do so may
result in electric shock, fire, or malfunction.
3. Allow enough space around the Temperature Controller to
ensure proper heat dissipation. Do no block the ventilating
holes.
4. Be sure to wire properly with correct polarity of terminals.
5. To wire the E5AN, E5EN, or E5CN using crimp terminals, use
crimp terminals designed for M3.5 screws and with a width of
7.2 mm max.
Do not use the Temperature Controller in locations
subject to flammable or explosive gases. Doing so
may result in an explosion.
The switching capacity and switching conditions will
significantly affect the longevity of the output relays.
Use the Temperature Controller within the rated load,
and do not use the Temperature Controller beyond the
number of operations specified under electrical life.
Using the Temperature Controller beyond its electrical
life may result in contact welding or burning.
7.2 mm max.
6. When wiring the E5GN, use a cable gauge of AWG24
(0.205 mm2) to AWG14 (2.081 mm2) for terminals 1 to 6, and
use a cable gauge of AWG28 (0.081 mm2) to AWG22
(0.326 mm2) for terminals 7 to 9. The exposed current-carry-
ing part to be inserted into terminals must be 5 to 6 mm.
7. After wiring is completed, do not pull on or bend a terminal
block lead wire with a force of 30 N or higher.
8. Do not connect anything to unused terminals.
9. Make sure that the power supply voltages and loads are
within specification and rating ranges before using the Tem-
perature Controller.
10. To avoid inductive noise, keep the wiring for the Temperature
Controller's terminal board away from power cables carrying
high voltages or large currents. Also, do not wire power lines
together with or parallel to Temperature Controller wiring.
Using shielded cables to separate pipes and ducts is recom-
mended.
Use Temperature Controller settings that are
appropriate for the controlled system. Failure to do so
may cause unexpected operation resulting in damage
to equipment or personal injury
Prepare a circuit with an overheating prevention alarm
and implement other safety measures to ensure safe
operation in the event of a malfunction. Loss of
operational control due to malfunction may result in a
serious accident.
Tighten the terminal screws to the following
torque:
M3.5 screws: 0.74 to 0.90 N·m
M3 screws: 0.40 to 0.56 N·m
E5GN: Terminals 1 to 6: 0.23 to 0.25 N·m
Terminals 7 to 9: 0.12 to 0.14 N·m
Attach surge absorbers or noise filters to peripheral devices
that generate noise (e.g., motors, transformers, solenoids,
magnetic coils, or other equipment that has an inductance
element). If using a noise filter with the power supply, be sure
to confirm the voltage and the current, and then mount the
power supply as near as possible to the Temperature Con-
troller.
Set up the Temperature Controller, along with its power sup-
ply, as far away as possible from devices that generate
strong, high-frequency waves, such as high-frequency weld-
ers and high-frequency machines, and from devices that gen-
erate surges.
Failure to tighten terminal screws to the correct torque
may result in fire or malfunction.
Make sure there will be no adverse affects from the
device connected to the Temperature Controller
before using the hardware test mode. Devices
connected to the Temperature Controller may reach a
dangerous state during the test.
11. Make sure that the rated voltage is attained within two sec-
onds of turning the power ON.
12. Allow at least 30 seconds for the Temperature Controller to
warm up.
13. When using self-tuning, turn ON power for the load (e.g.,
heater) at the same time as or before supplying power to the
Temperature Controller. If power is turned ON for the Tem-
perature Controller before turning ON power for the load,
self-tuning will not be performed properly and optimum con-
trol will not be achieved.

C-1
Precautions for Correct Use
14. In order that power can be turned OFF in an emergency by
the person operating the Temperature Controller, install the
appropriate switches and circuit breakers, and label them
accordingly.
15. Turn OFF the power before drawing out the Temperature
Controller body. Do not touch or apply excessive force to the
terminals or electronic parts. When inserting the body, make
sure that electronic parts do not come in contact with the
case.
16. When the terminal block for the E5GN is detached, do not
touch or apply excessive force to any electronic parts.
17. Use alcohol to clean the Temperature Controller. Do not use
thinner or other solvent-based substances.
18. Inverters with an output frequency of 50/60 Hz are available,
but they may cause the internal temperature of Temperature
Controller to rise, possibly resulting in smoke or burning. Do
not use an inverter output to supply power to a Temperature
Controller.
● Service Life
1. Use the Temperature Controller within the specified temperature
and humidity ranges. If the product is installed inside a control
panel, the temperature around the Temperature Controller and
not the temperature around the control panel must be kept within
the specified temperature range.
2. The service life of electronic devices such as Temperature
Controllers is determined not only by the number of switching
operations performed by the relay, but also by the service life
of the internal electronic components. The service life of
these components depends on the ambient temperature: it
will be shorter if the ambient temperature is high and longer if
the ambient temperature is low. For this reason, the service
life of the product can be extended by keeping the internal
temperature of the Temperature Controller low.
3. If several Temperature Controllers are mounted side-by-side
or are arranged vertically, the heat generated by them may
cause the internal temperature of the products to rise, thus
reducing their service life. To prevent this, take steps to
ensure that the Temperature Controllers are cooled, such as
installing fans. When providing forced cooling, however, be
careful not to cool down the terminal sections alone to avoid
measurement errors.
● Measurement Accuracy
1. When extending the lead wires for thermocouples, use a com-
pensating conductor appropriate for the type of thermocouple
use.
2. When extending the lead wires for platinum resistance ther-
mometers, use lead wires with low resistance, and make the
resistance in the 3 lead wires equal.
3. The type of Temperature Sensor and the input type for the
Temperature Controller must be set the same.
4. There are two types of platinum resistance thermometers: Pt
and JPt. Accurate measurement will not be possible if the
input type for the Temperature Sensor is not set correctly.
5. Mount the Temperature Controller horizontally.
6. If significant errors occur, check to see if the input shift has
been set correctly.
● Waterproofing
Sections without any specification on their degree of protection or
those with IP@0 specifications are not waterproof.
● EN/IEC Compliance
Installing the following fuse in the power supply terminal block is rec-
ommended if the Temperature Controller is used in applications
requiring EN/IEC compliance.
Recommended fuse: A T2A, 250-VAC, time lag fuse with low break-
ing capacity
● Operating Precautions
1. It takes approximately five seconds for the outputs to turn ON
from the moment the power is turned ON. Due consideration
must be given to this time when incorporating Temperature Con-
trollers in a sequence circuit.
2. When using the self-tuning capability of the E5@N, E5@K, or
E5@J, supply power to the load (e.g., heater) at the same
time as or before supplying power to the Temperature Con-
troller. If power is turned ON for the Temperature 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 Temperature 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 Temperature Controller OFF and ON again,
switching from STOP mode to RUN mode can also be used in
this case.)
3. The reception of the Temperature Controller may be affected
if it is used close to radios, television sets or wireless
devices.
