warranty repairs, you will be billed according to the cost of replacement materials,
service time and freight. Please consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. For example, CPU
speed, Advantech products used, other hardware and software used, etc. Note
anything abnormal and list any on-screen messages you get when the problem
occurs.
2. Call your dealer and describe the problem. Please have your manual, product,
and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return merchandize
authorization) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a fully-completed Repair and Replacement
Order Card and a photocopy proof of purchase date (such as your sales receipt)

Safety Precaution - Static Electricity
Static electricity can cause bodily harm or damage electronic devices. To avoid dam-
age, keep static-sensitive devices in the static-protective packaging until the installa-
tion period. The following guidelines are also recommended:
Wear a grounded wrist or ankle strap and use gloves to prevent direct contact
with the device before servicing the device. Avoid nylon gloves or work clothes,
which tend to build up a charge.
Always disconnect the power from the device before servicing it.
Before plugging a cable into any port, discharge the voltage stored on the cable
by touching the electrical contacts to the ground surface.

Installation

8 EKI-1242NR Series User Manual
2.1 Installation Guidelines
The following guidelines are provided to optimize the device performance. Review
the guidelines before installing the device.
Make sure cabling is away from sources of electrical noise. Radios, power lines,
and fluorescent lighting fixtures can interference with the device performance.
Make sure the cabling is positioned away from equipment that can damage the
cables.
Operating environment is within the ranges listed range, see “Specifications” on
page 2.
Relative humidity around the fieldbus gateway does not exceed 95 percent
(noncondensing).
Altitude at the installation site is not higher than 10,000 feet.
In 10/100 and 10/100/1000 fixed port devices, the cable length from the fieldbus
gateway to connected devices can not exceed 100 meters (328 feet).
Make sure airflow around the fieldbus gateway and respective vents are
unrestricted. Without proper airflow, the fieldbus gateway can overheat. To
prevent performance degredation and damage to the fieldbus gateway, make
sure there is clerance at the top and bottom and around the exhaust vents.
2.1.1 Connecting Hardware
In this instruction, it will explain how to find a proper location for your Fieldbus
Gateways, and how to connect to the network, hock up the power cable, and connect
to the EKI-1242NR Series.
2.2 Verifying Fieldbus Gateway Operation
Before installing the device in a rack or on a wall, power on the fieldbus gateway to
verify that the fieldbus gateway passes the power-on self-test (POST). To connect
the cabling to the power source see “Power Supply Installation” on page 16.
At startup (POST), the System LED blinks green, while the remaining LEDs are a
solidy green. Once the fieldbus gateway passes POST self-test, the System LED
turns green. The other LEDs turn off and return to their operating status. If the
fieldbus gateway fails POST, the System LED fieldbus gateways to an amber state.
After a successful self-test, power down the fieldbus gateway and disconnect the
power cabling.
The fieldbus gateway is now ready for installation on its final location.

EKI-1242NR Series User Manual 9
2.3 Installing the Fieldbus Gateway
2.3.1 DIN Rail Mounting
The DIN rail mount option is the quickest installation option. Additionally, it optimizes
the use of rail space.
The metal DIN rail kit is secured to the rear of the fieldbus gateway. The device can
be mounted onto a standard 35 mm (1.37”) x 7.5 mm (0.3”) height DIN rail. The
devices can be mounted vertically or horizontally. Refer to the following guidelines for
further information.
2.3.1.1 Installing the DIN-Rail Mounting Kit
1. Position the rear panel of the fieldbus gateway directly in front of the DIN rail,
making sure that the top of the DIN rail clip hooks over the top of the DIN rail, as
shown in the following illustration.
Make sure the DINrail is inserted behind the spring mechanism.
2. Once the DIN rail is seated correctly in the DIN rail clip, press the front of the
fieldbus gateway to rotate the fieldbus gateway down and into the release tab
on the DIN rail clip.
If seated correctly, the bottom of the DIN rail should be fully inserted in the
release tab.
Figure 2.1 Installing the DIN-Rail Mounting Kit
Note! A corrosion-free mounting rail is advisable.
When installing, make sure to allow for enough space to properly install
the cabling.
Warning! Do not install the DIN rail under or in front of the spring mechanism on
the DIN rail clip to prevent damage to the DIN rail clip or the DIN rail.

See the following figure for an illustration of a completed DIN installation proce-
dure.
Figure 2.2 Correctly Installed DIN Rail Kit
3. Grasp the bottom of the fieldbus gateway and slightly rotate it upwards. If there
is resistance, the fieldbus gateway is correctly installed. Otherwise, re-attempt
the installation process from the beginning.
2.3.1.2 Removing the DIN-Rail Mounting Kit
1. Ensure that power is removed from the fieldbus gateway, and disconnect all
cables and connectors from the front panel of the fieldbus gateway.
2. Push down on the top of the DIN rail clip release tab with your finger. As the clip
releases, lift the bottom of the fieldbus gateway, as shown in the following
illustration.
\
Figure 2.3 Removing the DIN-Rail

EKI-1242NR Series User Manual 11
2.3.2 Wall-Mounting
The wall mounting option provides better shock and vibration resistance than the DIN
rail vertical mount.
Before the device can be mounted on a wall, you will need to remove the DIN rail
plate.
1. Rotate the device to the rear side and locate the DIN mounting plate.
2. Remove the screws securing the DIN mounting plate to the rear panel of the
fieldbus gateway.
3. Remove the DIN mounting plate. Store the DIN mounting plate and provided
screws for later use.
4. Align the wall mounting plates on the rear side. The screw holes on the device
and the mounting plates must be aligned, see the following illustration.
5. Secure the wall mount plates with M3 screws, see the following figure.
Figure 2.4 Installing Wall Mount Plates
Once the wall mounting plates are secure on the device, you will need to attach the
wall screws (x4).
6. Locate the installation site and place the fieldbus gateway against the wall,
making sure it is the final installation location.
7. Use the wall mount plates as a guide to mark the locations of the screw holes.
8. Drill four holes over the four marked locations on the wall, keeping in mind that
the holes must accommodate wall sinks in addition to the screws.
Note! When installing, make sure to allow for enough space to properly install
the cabling.
