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.Do not exceed the communications distance that is given in the

specifications and use the specified communications cable. 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.

30.Noise may enter on the USB-Serial Conversion Cable, possibly

causing equipment malfunctions. Do not leave the USB-Serial

Conversion Cable connected constantly to the equipment.

31.For the E5DC/E5DC-B, when you attach the Main Unit to the

Terminal Unit, make sure that the hooks on the Main Unit are

securely inserted into the Terminal Unit.

32.For the E5CC-U, when you attach the Main Unit to the socket,

make sure that the hooks on the socket are securely inserted into

the Main Unit.

33.Install the DIN Track vertically to the ground.

34.For the E5DC/E5DC-B, always turn OFF the power supply before

connecting the Main Unit to or disconnecting the Main Unit from

the Terminal Unit, and never touch nor apply shock to the

terminals or electronic components. When connecting or

disconnecting the Main Unit, do not allow the electronic

components to touch the case.

35.Observe the following precautions when you remove the terminal

block or pulling out the interior of the product of the E5GC.

• Always follow the instructions provided in the E5

@C Digital

Temperature Controllers User’s Manual (Cat. No. H174).

• Turn OFF the power supply before you start and never touch nor

apply shock to the terminals or electric components. When you

insert the interior body of the Digital Temperature Controller, do

not allow the electronic components to touch the case.

• Check for any corrosion on the terminals.

• When you insert the interior body into the rear case, confirm that

the hooks on the top and bottom are securely engaged with the

case.

36.Observe the following precautions when you wire the E5

@C-B.

• Always follow the wiring instructions provided in Wiring

Precautions for E5

@C-B (Controllers with Push-In Plus

Terminal Blocks)

on page 133.

• Do not wire anything to the release holes.

• Do not tilt or twist a flat-blade screwdriver while it is inserted into

a release hole on the terminal block. The terminal block may be

damaged.

• Insert a flat-blade screwdriver into the release holes at an angle.

The terminal block may be damaged if you insert the

screwdriver straight in.

• Do not allow the flat-blade screwdriver to fall out while it is

inserted into a release hole.

• Do not bend a wire past its natural bending radius or pull on it

with excessive force. Doing so may cause the wire to break.

• Do not use crossover wiring except for the input power supply

and communications.

• Do not use crossover wiring for the E5CC-B/E5EC-B except for

the input power supply and communications.

Do not use crossover wiring for the E5DC-B.

The E5CC, E5CC-B, E5CC-U, E5EC, E5EC-B, E5AC, and E5DC

comply with Lloyd's standards. When applying the standards, the

following installation requirements must be met in the application.

Also insert the Waterproof Packing on the backside of the front panel.

Application Conditions

Installation Location

The E5CC, E5CC-B, E5CC-U, E5EC, E5EC-B, E5AC, and E5DC

comply with installation category ENV1 and ENV2 of Lloyd's

standards. Therefore, they must be installed in a location equipped

with air conditioning. They cannot be used on the bridge or decks, or

in a location subject to strong vibration.

Service Life

1. Use the product within the following temperature and humidity ranges:

Temperature: -10 to 55°C (with no icing or condensation)

Humidity:

25% to 85%

If the product is installed inside a control board, the ambient

temperature must be kept to under 55°C, including the temperature

around the product.

2. The service life of electronic devices like Digital Temperature

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

Temperature Controller.

3. When two or more Digital Temperature 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 Temperature 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 Temperature Controllers. When

providing forced cooling, however, be careful not to cool down the

terminals sections alone to avoid measurement errors.
