A Network Installation - Omron CS1W-ETN01 Operation Manuals

Basic Installation Precautions
• Take the greatest care when installing the Ethernet System, being sure to follow ISO 8802-3 specifications. You
must obtain a copy of these specifications and be sure you understand them before attempting to install an
Ethernet System. Unless you are already experienced in installing communications systems, we strongly rec-
ommend that you employ a professional to install your system.
• Do not install Ethernet equipment near sources of noise. If noise-prone environments are unavoidable, be sure
to take adequate measures against noise interference, such as installing network components in grounded met-
al cases, using optical links in the system, etc. Further information on measures that can be taken against noise
is given later in this section.
Recommended Products
The following products are recommended for use with the CS1W-ETN01 Ethernet Unit.
Coaxial Cable Installation Precautions
Basic Precautions
• As a rule, always lay coaxial cables indoors. Laying coaxial cables outdoors requires special measures that
should be performed only by a professional. If coaxial cable must be used outdoors, request the work from a
professional.
• Attach a terminator to each end of the coaxial cable.
• Cover all exposed metal portions of the coaxial cable except ground points with protective covers or PVC tape to
prevent contact with grounds or other metal objects.
• Ground the external shield of the coaxial cable to 100 W or less using AWG 14 wire (cross-sectional area of 2
2
mm ) or better and a ground cable length of 20 m or less. Ground each segment of the network at one location
only. Do not use the same ground for other equipment.
• The physical properties (e.g., minimum bending radius) of coaxial cable vary with the manufacturer. Follow all
recommendations and specifications of the manufacturer.
Environmental Precautions
• Do not install coaxial cables together with power cables.
• Do not install coaxial cable near sources of noise.
• Do not install coaxial cable in environments subject to excessive dirt, dust, oil mist, etc.
• Do not install coaxial cable in environments subject to high temperatures or high humidity.
Terminator Installation Precautions
• You must attach a Terminator to each end of the coaxial cable for communications to be possible.
• Insulate Terminators when attaching them to be sure they do not come into contact with metal objects.
