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. Do not

handle the Digital Temperature Controller in ways that exceed the

ratings.

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 Digital Temperature Controllers, or

mounting Digital Temperature Controllers above each other may

cause heat to build up inside the Digital 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 Digital

Temperature Controller.

Do not block the ventilation holes on the Digital Temperature

Controller.

4. Be sure to wire properly with correct signal name and polarity of

terminals.

5. Use the specified size of crimped terminals (M3, width of 5.8 mm

or less) to wire the E5CC, E5EC, E5AC, E5DC, or E5

@C-T. To

connect bare wires to the terminal block of the E5CC, E5EC,

E5AC, E5DC, or E5

@C-T, use copper braided or solid wires with

a gage of AWG24 to AWG18 (equal to a cross-sectional area of

0.205 to 0.823 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.

Use the specified size of crimped terminals (M3.5, width of 7.2 mm

or less) to wire the E5CC-U. To connect bare wires to the terminal

block of the E5CC-U, use copper braided or solid wires with a

gage of AWG24 to AWG14 (equal to a cross-sectional area of

0.205 to 2.081 mm2). (The stripping length is 5 to 6 mm.) Up to two

wires of the same size and type, or two crimped terminals can be

inserted into a single terminal.

Use the specified size of crimped terminals (M3, width of 5.8 mm

or less) to wire the E5GC.*

To connect bare wires to the terminal block of the E5GC, use

copper braided or solid wires with a gauge of AWG24 to AWG18

(equal to a cross-sectional area of 0.205 to 0.823 mm2). (The

stripping length for Digital Temperature Controllers with screw

terminal blocks is 6 to 8 mm. The stripping length for Digital

Temperature Controllers with screwless clamp terminal blocks is 8

to 12 mm.)

Up to two wires of the same size and type, or two crimped

terminals can be inserted into a single terminal. When connecting

two wires into one terminal of a Digital Temperature Controller with

a screwless clamp terminal block, use ferrules with a diameter of

0.8 to 1.4 mm and an exposed conductor length of 8 to 12 mm that

two wires are crimped for a ferrule.*

* The Digital Temperature Controller with screwless clamp

terminals underwent UL testing with one braided wire connected.

6. Do not wire the terminals that are not used.

7. Use a commercial power supply for the power supply voltage input

to a Digital Temperature Controller with AC input specifications.

Do not use the output from an inverter as the power supply.

Depending on the output characteristics of the inverter,

temperature increases in the Digital Temperature Controller may

cause smoke or fire damage even if the inverter has a specified

output frequency of 50/60 Hz.

8. 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.

9. Use this product within the rated load and power supply.

10.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.

11.Make sure that the Digital 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.

12.When executing self-tuning with E5

@C, turn ON power to the load

(e.g., heater) at the same time as or before supplying power to the

product. If power is turned ON to the product before turning ON

power to the load, self-tuning will not be performed properly and

optimum control will not be achieved.

13.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.

14.Use a soft and dry cloth to clean the product carefully. Do not use

organic solvent, such as paint thinner, benzine or alcohol to clean

the product.

15.Design the system (e.g., control panel) considering the 2 seconds

of delay that the product's output to be set after power ON.

16.The output may turn OFF when you move to the initial setting level.

Take this into consideration when performing control operations.

17.The number of non-volatile memory write operations is limited.

Therefore, use RAM write mode when frequently overwriting data

during communications or other operations.

18.Always touch a grounded piece of metal before touching the

Digital Temperature Controller to discharge static electricity from

your body.

19.Use suitable tools when taking the Digital Temperature Controller

apart for disposal. Sharp parts inside the Digital Temperature

Controller may cause injury.

20.For compliance with Lloyd’s standards, the E5CC, E5CC-U,

E5EC, and E5AC must be installed under the conditions that are

specified in Shipping Standards.

21.For the Digital Temperature Controller with two Setup Tool ports

(E5EC/E5AC/E5DC/E5GC), do not connect cables to both ports at

the same time. The Digital Temperature Controller may be

damaged or may malfunction.

22.Do not place heavy object on the Conversion Cable, bend the

cable past its natural bending radius, or pull on the cable with

undue force.

23.Do not disconnect the Communications Conversion Cable or the

USB-Serial Conversion Cable while communications are in

progress. Damage or malfunction may occur.

24.Do not touch the external power supply terminals or other metal

parts on the Digital Temperature Controller.

25.Refer to the E5

@C Digital Temperature Controllers User’s Manual

(Cat. No. H174) for information on the communications distances

and cables for the E5

@C.

For details on the E5

@C-T, refer to the E5

@C-T Digital

Temperature Controllers Programmable Type User’s Manual (Cat.

No. H185).

26.Do not bend the communications cables past their natural bending

radius. Do not pull on the communications cables.

27.Do not turn the power supply to the Digital Temperature Controller

ON or OFF while the USB-Serial Conversion Cable is connected.

The Digital Temperature Controller may malfunction.

28.Make sure that the indicators on the USB-Serial Conversion Cable

are operating properly. Depending on the application conditions,

deterioration in the connectors and cable may be accelerated, and

normal communications may become impossible. Perform

periodic inspection and replacement.

29.Connectors may be damaged if they are inserted with excessive

force. When connecting a connector, always make sure that it is

oriented correctly. Do not force the connector if it does not connect

smoothly.
