It is extremely important that a PLC and all PLC Units be used for the speci-
fied purpose and under the specified conditions, especially in applications that
can directly or indirectly affect human life. You must consult with your OMRON
representative before applying a PLC system to the above mentioned applica-
tions.
Never attempt to disassemble any Units or touch the terminal block while
power is being supplied. Doing so may result in serious electrical shock.
Do not apply voltages or currents outside the specified ranges to a Slice I/O
Unit. Doing so may cause a malfunction or fire.
Always turn OFF the I/O power supply to the I/O Unit before performing online
replacement or connecting/disconnecting wiring, including fixing a loose wire.
In addition, if external power is supplied to the terminal block for a Unit such
as a Relay Output Unit or AC Input Unit, turn OFF that power supply before
replacing the Unit. Not turning OFF these power supplies may result in false
output signals, false input signals, or electrical shock.
