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 modbus router does not exceed 95 percent
(noncondensing).

Altitude at the installation site is not higher than 10,000 feet.

In 10/100 fixed port devices, the cable length from the modbus router to
connected devices cannot exceed 100 meters (328 feet).

Make sure airflow around the modbus router and respective vents are
unrestricted. Without proper airflow, the modbus router can overheat. To prevent
performance degradation and damage to the modbus router, make sure there is
clearance 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 Modbus
Routers, and how to connect to the network, hock up the power cable, and connect to
the EKI-122xR-CE Series.
2.2 Verifying Modbus Router Operation
Before installing the device in a rack or on a wall, power on the modbus router to
verify that the modbus router passes the power-on self-test (POST). To connect the
cabling to the power source see “Power Supply Installation” on page 18.
At startup (POST), the System LED blinks green, while the remaining LEDs are a
solidy green. Once the modbus router passes POST self-test, the System LED turns
green. The other LEDs turn off and return to their operating status. If the modbus
router fails POST, the System LED modbus routers to an amber state.
After a successful self-test, power down the modbus router and disconnect the power
cabling.
The modbus router is now ready for installation on its final location.
