Application Precautions
Observe the following precautions when using the MULTIPLE I/O TERMINAL.
WARNING
Failure to abide by the following precautions could lead to serious or possibly
fatal injury. Always heed these precautions.
•
Always ground the system to 100
Ω
or less when installing the system to
protect against electrical shock.
•
Always turn OFF the power supply to the system before attempting any of the
following. Performing any of the following with the power supply turned ON
may lead to electrical shock:
•
Mounting or removing any Units (e.g., I/O Units, CPU Unit, etc.) or memory
cassettes.
•
Assembling any devices or racks.
•
Connecting or disconnecting any cables, connectors, or wiring.
Caution
Failure to abide by the following precautions could lead to faulty operation of or
damage to the MULTIPLE I/O TERMINAL. Always heed these precautions.
•
Use the Units only with the power supplies and voltages specified in the
operation manuals. Other power supplies and voltages may damage the
Units.
•
Take measures to stabilize the power supply to conform to the rated supply if it
is not stable.
•
Provide circuit breakers and other safety measures to provide protection
against shorts in external wiring.
•
Do not apply voltages exceeding the rated input voltage to Input Units. The
Input Units may be destroyed.
•
Do not apply voltages exceeding the maximum switching capacity to Output
Units. The Output Units may be destroyed.
•
Install all Units according to instructions in the operation manuals. Improper
installation may cause faulty operation.
•
Be sure to tighten Backplane screws, terminal screws, and cable connector
screws securely.
•
Do not attempt to take any Units apart, to repair any Units, or to modify any
Units in any way.
•
Do not use communications cables or I/O cables in parallel to or close to
high-tension, high-rate current carrying lines. Doing so may cause faulty
operation
