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.
