Safety Precautions - IDEC FT1A Series User Manual

S P
AFETY RECAUTIONS
Read the SmartAXIS Pro/Lite User's Manual to ensure correct operation before starting installation, wiring, operation, maintenance, and
•
inspection of the SmartAXIS.
All SmartAXIS 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 SmartAXIS in applications where heavy damage or personal injury may be caused, in case the SmartAXIS should
fail.
In this user's manual, safety precautions are categorized in order of importance:
•
Warning
Warning notices are used to emphasize that improper operation may cause severe personal injury or death.
The SmartAXIS is not designed for use in medical equipment, nuclear power, railways, aviation, passenger vehicle equipment, or similar
•
applications requiring a high degree of reliability and safety. The SmartAXIS should not be used for such applications.
When using the SmartAXIS in applications (not described above) that require a high degree of reliability in terms of functionality and precision,
•
appropriate measures such as failsafe mechanisms and redundant mechanisms must be taken for the system containing the SmartAXIS.
Emergency stop and interlocking circuits must be configured outside the SmartAXIS.
•
If relays or transistors in the SmartAXIS output circuits should fail, outputs may remain at on or off state. For output signals which may cause
•
serious accidents, configure monitor circuits outside the SmartAXIS.
The SmartAXIS self-diagnostic function may detect internal circuit or program errors, stop programs, and turn outputs off. Configure circuits
•
so that the system containing the SmartAXIS is not jeopardized when outputs turn off.
Turn off power to the SmartAXIS before installation, removal, wiring, maintenance, and inspection of the SmartAXIS. Failure to turn power off
•
may cause electrical shocks or fire hazard.
Special expertise is required to install, wire, program, and operate the SmartAXIS. People without such expertise must not use the SmartAXIS.
•
Install the SmartAXIS according to the instructions described in SmartAXIS Pro/Lite user's manual. Improper installation will result in falling,
•
failure, or malfunction of the SmartAXIS.
Caution
Caution notices are used where inattention might cause personal injury or damage to equipment.
The SmartAXIS is designed for installation in a cabinet. Do not install the SmartAXIS outside a cabinet.
•
Install the SmartAXIS in environments described in the SmartAXIS Pro/Lite user's manual. If the SmartAXIS is used in places where the
•
SmartAXIS is subjected to high-temperature, high-humidity, condensation, corrosive gases, excessive vibrations, or excessive shocks, then
electrical shocks, fire hazard, or malfunction will result.
The environment for using the SmartAXIS is "Pollution degree 2." Use the SmartAXIS in environments of pollution degree 2 (according to IEC
•
60664-1).
Prevent the SmartAXIS from falling while moving or transporting the SmartAXIS, otherwise damage or malfunction of the SmartAXIS will result.
•
Wiring must use lead sizes that are appropriate for the applied voltage and current. Terminal screws must be tightened with the prescribed
•
tightening torque.
Prevent metal fragments and pieces of wire from dropping inside the SmartAXIS housing. Put a cover on the SmartAXIS 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 SmartAXIS. This is required when equipment containing the SmartAXIS is
•
destined for Europe.
Use an IEC 60127-approved fuse on the output circuit. This is required when equipment containing the SmartAXIS is destined for Europe.
•
Use an EU-approved circuit breaker. This is required when equipment containing the SmartAXIS is destined for Europe.
•
Make sure of safety before starting and stopping the SmartAXIS or when operating the SmartAXIS to force outputs on or off. Incorrect operation
•
of the SmartAXIS may cause machine damage or accidents.
Do not connect the ground wire directly to the SmartAXIS. Connect a protective ground to the cabinet containing the SmartAXIS using an M4 or
•
larger screw. This is required when equipment containing the SmartAXIS is destined for Europe.
Do not disassemble, repair, or modify the SmartAXIS modules.
•
The SmartAXIS contains electronic parts and batteries. When disposing of the SmartAXIS, do so in accordance
•
with national and local regulations.
