RECAUTIONS
• Read this user’s manual to make sure of correct operation before starting installation, wiring, operation, maintenance, and
inspection of the Web server CPU module.
• All Web server CPU modules are manufactured under IDEC’s rigorous quality control system, but users must add a backup or
failsafe provision to the control system when using the Web server CPU module in applications where heavy damage or personal
injury may be caused in case the Web server CPU module should fail.
• In this user’s manual, safety precautions are categorized in order of importance to Warning and Caution:
• Turn off power to the Web server CPU module before installation, removal, wiring, maintenance, and inspection of the Web server
CPU module. Failure to turn power off may cause electrical shocks or fire hazard.
• 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.
• 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.
• Install the Web server CPU module according to the instructions described in this user’s manual. Improper installation will result in
falling, failure, or malfunction of the Web server CPU module.
• The Web server CPU module is designed for installation in a cabinet. Do not install the Web server CPU module outside a cabinet.
• Install the Web server CPU module in environments described in this user’s manual. If the Web server CPU module is used in places
where the Web server CPU module is subjected to high-temperature, high-humidity, condensation, corrosive gases, excessive
vibrations, and excessive shocks, then electrical shocks, fire hazard, or malfunction will result.
• 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).
• Prevent the Web server CPU module from falling while moving or transporting the Web server CPU module, otherwise damage or
malfunction of the Web server CPU module will result.
• 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.
• Use a power supply of the rated value. Use of a wrong power supply may cause fire hazard.
• Use an IEC 60127-approved fuse on the power line outside the Web server CPU module. This is required when equipment
containing the Web server CPU module is destined for Europe.
• Use an IEC 60127-approved fuse on the output circuit. This is required when equipment containing the Web server CPU module is
destined for Europe.
• Use an EU-approved circuit breaker. This is required when equipment containing the Web server CPU module is destined for
Europe.
• Make sure of safety before starting and stopping the Web server CPU module or when operating the Web server CPU module to
force outputs on or off. Incorrect operation on the Web server CPU module may cause machine damage or accidents.
• If relays or transistors in the Web server CPU modules should fail, outputs may remain on or off. For output signals which may
cause heavy accidents, provide a monitor circuit outside the Web server CPU module.
• Do not connect the ground wire directly to the Web server CPU module. Connect a protective ground to the cabinet containing the
Web server CPU module using an M4 or larger screw. This is required when equipment containing the Web server CPU module is
destined for Europe.
• Do not disassemble, repair, or modify the Web server CPU modules.
• Dispose of the battery in the Web server CPU modules when the battery is dead in accordance with pertaining regulations. When
storing or disposing of the battery, use a proper container prepared for this purpose. This is required when equipment containing
the Web server CPU module is destined for Europe.
• When disposing of the Web server CPU module, do so as an industrial waste.
Warning notices are used to emphasize that improper operation may cause severe personal injury or death. Warning
Caution notices are used where inattention might cause personal injury or damage to equipment. Caution
