2.2. 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 flu orescent
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 1.
» Relative humidity around the switch does not exceed 95 percent (non-condensing).
» 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 switch to con nected
devices can not exceed 100 meters (328 feet).
» Make sure airflow around the switch and respective vents is unrestricted. Without proper
airflow the switch can overheat. To prevent performance degradation and dam age to the
switch, make sure there is clearance at the top and bottom and around the exhaust vents.
2.3. Environment and Enclosure Guidelines
Review these environmental and enclosure guidelines before installation:
This equipment is intended for use in a Pollution Degree 2 industrial environment, in over-voltage
Category II applications (as defined in IEC publication 60664-1), at altitudes up to 9842 ft (3 km)
without derating.
This equipment is considered Group 1, Class A industrial equipment, according to IEC/ CISPR
Publication 11. Without appropriate precautions, there may be potential difficulties ensuring
electromagnetic compatibility in other environments due to conducted as well as radiated
disturbance.
This equipment is supplied as open-type equipment. It must be mounted within an enclo sure
that is suitably designed for those specific environmental conditions that will be present and
appropriately designed to prevent personal injury resulting from accessibility to live parts. The
enclosure must have suitable flame-retardant properties to prevent or minimize the spread of
flame, complying with a flame-spread rating of 5VA, V2, V1, V0 (or equivalent) if nonmetallic. The
interior of the enclosure must be accessible only by the use of a tool. Subsequent sections of this
publication might contain additional information regarding spe cific enclosure-type ratings that are
required to comply with certain product safety certifica tions.
2.3.1 Connecting Hardware
In this instruction, it will explain how to find a proper location for your Modbus Gateways, and how
to connect to the network, hock up the power cable, and connect to the managed Ethernet switch.
