Introduction
This chapter describes the methods and precautions for installing and wiring Web server CPU modules.
Before starting installation and wiring, be sure to read “Safety Precautions” in the beginning of this manual and
understand precautions described under Warning and Caution.
Installation Location
• Turn off the power to the Web server CPU module before starting installation, removal, wiring,
maintenance, and inspection of the Web server CPU module. Failure to turn power off may cause electrical
shocks or fire hazard.
• Emergency stop and interlocking circuits must be configured outside the Web server CPU module. If such a
circuit is configured inside the Web server CPU module, failure of the Web server CPU module may cause
disorder of the control system, damage, or accidents.
• Special expertise is required to install, wire, program, and operate the Web server CPU module. People
without such expertise must not use the Web server CPU module.
Warning
• Prevent metal fragments and pieces of wire from dropping inside the Web server CPU module housing. Put
a cover on the Web server CPU modules during installation and wiring. Ingress of such fragments and chips
may cause fire hazard, damage, or malfunction.
• Do not touch the connector pins with hand, otherwise electrostatic discharge may damage the internal
elements.
• Keep the Web server CPU module wiring away from motor lines.
Caution
The Web server CPU module must be installed correctly for optimum performance.
The Web server CPU module is designed for installation in a cabinet. Do not install the Web server CPU module outside
a cabinet.
The environment for using the Web server CPU module is “Pollution degree 2.” Use the Web server CPU module in
environments of pollution degree 2 (according to IEC 60664-1).
Make sure that the operating temperature does not drop below 0°C or exceed 55°C. If the temperature does exceed
55°C, use a fan or cooler.
Mount the Web server CPU module on a vertical plane as shown at
right.
To eliminate excessive temperature build-up, provide ample
ventilation. Do not install the Web server CPU module near, and
especially above, any device which generates considerable heat, such
as a heater, transformer, or large-capacity resistor. The relative
humidity should be above 30% and below 95%.
The Web server CPU module should not be exposed to excessive dust,
dirt, salt, direct sunlight, vibrations, or shocks. Do not use the Web
server CPU module in an area where corrosive chemicals or
flammable gases are present. The modules should not be exposed to
chemical, oil, or water splashes.
