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 copper stranded or solid wires to connect bare wires.

Recommended Wire

*1. Please use Ferrules with UL certification (R/C).

Use the specified size of crimped terminals to wire the E5CC,

E5EC, E5AC, E5DC, and E5GC (models with screw terminal

blocks) and the E5

@C-T and E5CC-U (plug-in models).

Recommended Crimped Terminal Size

For the E5

@C-B(Push-In Plus model), connect only one wire to

each terminal.

For other models, up to two wires of same size and type, or two

crimp terminals, can be inserted into a single terminal.

When connecting two wires to one terminal on an E5GC Digital

Temperature Controller with a screwless clamp terminal blocks,

use two crimped ferrules with a diameter of 0.8 to 1.4 mm and an

exposed conductor length of 8 to 12 mm.

*2. The E5GC Digital Temperature Controller with screwless

clamp terminal blocks 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-B,

E5EC-B, E5CC-U, E5EC, E5AC, and E5DC must be installed

under the conditions that are specified in Shipping Standards.

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

(E5EC/E5EC-B/E5AC/E5DC/E5DC-B/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. The Digital Temperature Controller may be

damaged.
