E5@C/E5@C-T
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
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

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.

Shipping Standards

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.
Precautions for Correct Use
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.
