The optical fiber connection supports the line to instruct enhance
the reliability of network effectively.
Suppose: If you make your own cable, we suggest labeling the two
sides of the same line with the same letter (A-to-A and B-to-B,
shown as below, or A1-to-A2 and B1-to-B2).

Relay contact:
The relay consists of the two middle contacts of the terminal block
on IT-ES308-IU-2F’s top panel. The two terminal block connector
are used to detect both power faults and port faults. The two wires
attached to the Fault contacts form an open circuit when:
(1) IT-ES308-IU-2F have lost power from one of the DC power
inputs, One of the ports for which the corresponding Port alarm DIP
Switch is set to ON is not properly connected.
If neither of these two conditions occur, the alarm circuit will be
closed.
Power Input:
IT-ES308-IU-2F have redundant power input, provides one terminal
block (4 bits) for PWR1 and PWR2 input. The redundant power can
be used single and used two self-governed power to supply to the
system, PWR1 and PWR2 input at the same time, when neither of
these two power fails, the other power acts as a backup, and
automatically supplies power needs, ensure running Ethernet
reassuring .

Switch Settings:
Provide 10 bits switch for function setting. 1～8 alarm enable
switch setting. ON show enable, 9 show PWR1 alarm setting .10
show PWR 2 alarm setting. ON show alarm state.
Installation：
Before installation, confirm that the work environment meet the
installation require, including the power needs and abundant space.
Whether it is close to the connection equipment and other
equipment are prepared or not.
Installation require as below
1. Avoid in the sunshine, keep away from the heat fountainhead or
the area where in intense EMI.
2. Examine the cables and plugs that installation requirements.
3. Examine whether the cables be seemly or not (less than 100m)
according to reasonable scheme.
4. Screw, nut, tool provide by yourself.
5. Power need: Redundant, dual 24VDC (12VDC~48VDC)
6. Environment: -40 to 75°C
Storage Temperature: -45°C to 85°C
Relative humidity 10% to 95%
DIN-Rail Installation
In order to use in industrial environments expediently,
IT-ES308-IU-2F adopt 35mm DIN-Rail installation, the installation
steps as follows:
1. Examine the DIN-Rail attachment
2. Examine DIN Rail whether be firm and the position be suitability

9
or not.
3. Insert the top of the DIN-Rail into the slot just below the stiff
metal spring.
4. The DIN-Rail attachment unit will insert into place as shown
below.
Wiring Requirements：
Be sure to disconnect the power cord before installing and/or wiring
your Ethernet Switch.
Calculate the maximum possible current in each power wire and
common wire. Observe all electrical codes dictating the maximum
current allowable for each wire size. If the current goes above the
maximum ratings, the wiring could overheat may causing serious
damage to your equipment. You should also pay attention to the
following items:
1. Use separate path to route wiring for power and devices. If power
wiring and device wiring paths must cross, make sure the wires
are perpendicular at the intersection point.
2. NOTE: Do not run signal or communications wiring and power
wiring in the same wire conduit. To avoid interference, wires
with different signal characteristics should be routed separately.
3. You can use the type of signal transmitted through a wire to
determine which wires should be kept separate. The rule of

10
thumb is that wiring that shares similar electrical characteristics
can be bundled together.
4. Keep input and output wiring separated. It is strongly advised
that you label wiring to all devices in the system when necessary.
