xiv
Always heed these precautions. Failure to abide by the following precautions
could lead to serious or possibly fatal injury.
• Always connect to a ground of 100 Ω or less when installing the ID Sen-
sor systems. Not connecting to a ground of 100 Ω or less may result in
electric shock.
• Always turn OFF the power supply to the PC before attempting any of the
following. Not turning OFF the power supply may result in malfunction or
electric shock.
• Mounting or dismounting Power Supply Units, I/O Units, CPU Units,
Memory Cassettes, or any other Units.
• Assembling the Units.
• Setting DIP switches or rotary switches.
• Connecting cables or wiring the system.
• Connecting or disconnecting the connectors.
the PC or the system, or could damage the PC or PC Units. Always heed
these precautions.
• Always use the power supply voltages specified in the operation manuals.
An incorrect voltage may result in malfunction or burning.
• Take appropriate measures to ensure that the specified power with the
rated voltage and frequency is supplied. Be particularly careful in places
where the power supply is unstable. An incorrect power supply may result
in malfunction.
• Install external breakers and take other safety measures against short-cir-
cuiting in external wiring. Insufficient safety measures against short-cir-
cuiting may result in burning.
• Do not apply voltages to the Input Units in excess of the rated input volt-
age. Excess voltages may result in burning.
• Do not apply voltages or connect loads to the Output Units in excess of
the maximum switching capacity. Excess voltage or loads may result in
burning.
• Disconnect the functional ground terminal when performing withstand
voltage tests. Not disconnecting the functional ground terminal may result
in burning.
• Be sure that all the mounting screws, terminal screws, and cable connec-
tor screws are tightened to the torque specified in the relevant manuals.
Incorrect tightening torque may result in malfunction.
• Use crimp terminals for wiring. Do not connect bare stranded wires
directly to terminals. Connection of bare stranded wires may result in
burning.
• Double-check all wiring and switch settings before turning ON the power
supply. Incorrect wiring may result in burning.
• Be sure that the terminal blocks, Memory Units, expansion cables, and
other items with locking devices are properly locked into place. Improper
locking may result in malfunction.
• Check switch settings, the contents of the DM Area, and other prepara-
tions before starting operation. Starting operation without the proper set-
tings or data may result in an unexpected operation.
• Check the user program for proper execution before actually running it on
the system. Not checking the program may result in an unexpected oper-
ation.
• Confirm that no adverse effect will occur in the system before attempting
any of the following. Not doing so may result in an unexpected operation.
