Relay contact:
Relay access terminals located on the top panel, the terminal is a

set of device alarm relay normally open contact, no alarm in the
normal state when the open state, when there is no warning
message when it is closed. IT-ES308-IU-4F to support a relay
alarm output, external warning light or alarm buzzer, also can
add other digital acquisition device so that in the event of an
alarm to alert the operator when a timely manner.
Power Input:
IT-ES308-IU-4F 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:
Top panel provides four DIP switch function is set (ON to enable
effective), 1 (ISP) for the program to load the serial port
selection, 2 to restore the factory settings; 3, 4 are reserved.

Changing the DIP switch status, must re-power.
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-4F 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 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
thumb is that wiring that shares similar electrical
characteristics can be bundled together.
4. Keep input and output wiring separated. It is strongly advised

10
that you label wiring to all devices in the system when
necessary.
