abnormality occurs due to malfunction of the PLC or another external factor
affecting the PLC operation. Not doing so may result in serious accidents.
xxiv
• Emergency stop circuit s, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits.
Safety Precautions 3
• The PLC will turn OFF all outputs when its self-diagnosis function detects
any error or when a severe f ailure alarm (FALS) instruction is execut ed.
Unexpected operation, however, may still occur for errors in the I/O control
section, errors in I/O memory, and errors that cannot be detected by the
self-diagnosis function. As a countermeasure for all these errors, external
safety measures must be provided to ensure safety in the system.
• The PLC or outputs may remain ON or OFF due to deposits on or burning
of the output relays, or destruction of the output transistors. As a countermeasure for such problems, external safety measures must be provided
to ensure safety in the system.
• When the 24-V DC output (service power supply to the PLC) is overloaded or short-circuited, the voltage may drop and result in the outputs
being turned OFF. As a countermeasure for such problems, external
safety measures must be provided to ensure safety in the system.
!WARNING Fail-safe measures must be taken by the customer to ensure safety in the
event of incorrect, missing, or abnormal signals caused by broken signal lines,
momentary power interruptions, or ot her causes. Not doing so may result in
serious accidents.
!WARNING Do not apply the voltage/current outside the specified range to this unit. It may
cause a malfunction or fire.
!Caution
Execute online edit only after confirming that no adverse effects will be cau sed
by extending the cycle time. Otherwise, the input signals may not be readable.
!Caution Confirm safety at the destination node before transferring a program to
another node or editing the I/O area. Doing either of these without confirming
safety may result in injury.
!Caution
Tighten the screws on the terminal block of the AC power supply to the torque
specified in this manual. The loose screws may result in burning or malfunctio n.
!Caution Do not touch anywhere near the power supply parts or I/O terminals while the

Operating Environment Precautions 4
!Caution After programming (or reprogra mming) using the IOWR instruction, confirm
that correct operation is possible with the new ladder program and data before
starting actual operation. Any irregularities may cause the product to stop
operating, resulting in unexpected operation in machinery or equipment.
!Caution The CP1L-EL/EM CPU Units automatically back up the user program and
parameter data to flash memory when these are written to the CPU Unit. I/O
memory (including the DM Area, counter present values and Completion
Flags, and HR Area), however, is not written to flash memory. The DM Area,
counter present values and Completion Flags, and HR Area can be held during power interruptions with a battery. If there is a battery error, the contents of
these areas may not be accu rate after a power interrupti on. If the co ntents o f
the DM Area, counter present values and Completion Flags, and HR Area are
used to control external outputs, prevent inappropriate outputs from being
made whenever the Battery Error Flag (A402.04) is ON.
4 Operating Environment Precautions
!Caution Do not operate and keep the control system in the following locations:
• Locations subject to direct sunlight.
• Locations subject to temperatures or humidity outside the range specified
in the specifications.

Application Precautions 5
• Do not connect pin 6 (+5V) on the RS-232C Option Board (CP1W-CIF01)
on the CPU Unit to any external device other than the NT-AL001 or
CJ1W-CIF11 Conversion Adapter. The external device and the CPU Unit
may be damaged.
• Use the dedicated connecting cables specified in this manual to connect
the Units. Using commercially available RS-232C computer cables may
cause failures in external devices or the CPU Unit.
• The user progr am an d pa ramet er ar ea d ata in the CPU Unit is b acked up
in the built-in flash memory. The BKUP indicator will light on the front of
the CPU Unit when the backup operation is in progress. Do not turn OFF
the power supply to the CPU Unit when the BKUP indicator is lit. The data
will not be backed up if power is turned OFF.
• Do not turn OFF the power supply to the PLC while the Memory Cassette
is being written. Doing so may corrupt the data in the Memory Cassette.
The BKUP indicator will light while the Memory Cassette is being written.
Wait for the BKUP indicator to go out before turning OFF the power supply to the PLC.
• Before replacing the battery, supply power to the CPU Unit for at least 5
minutes and then complete battery rep lacement within 5 minutes of turn
OFF the power supply. Memory data may be corrupted if this precaution is
not observed.
• Always use the following size wire when connecting I/O terminals:
2
AWG22 to AWG18 (0.32 to 0.82 mm
• Dispose of the product and batteries according to local ordinances as
they apply.
Have qualified specialists properly dispose of used batteries as industrial
waste.
).
• UL standards required that batteries be replaced only by experienced
technicians. Do not allow unqualified persons to replace batteries. Also,
always follow the replacement procedure provided in the manual.
• Never short-circuit the positive and negative terminals of a battery or
charge, disassemble, heat, or incinerate the battery. Do not subject the
battery to strong shocks or deform the barry by applying pressure. Doing
any of these may result in leakage, rupture, heat generation, or ignition of
the battery. Dispose of any battery that has been dropped on the floor or
otherwise subjected to excessive shock. Batteries that have been subjected to shock may leak if they are used.
• Always construct external circuits so that the power to the PLC it turned
ON before the power to the control system is turned ON. If the PLC power
supply is turned ON after the control power supply, temporary errors may
result in control system signals because the output terminals on DC Output Units and other Units will momentarily turn ON when power is turned
ON to the PLC.
• Fail-safe measures must be taken by the customer to ensure safety in the
event that outputs from Output Units remain ON as a result of internal circuit failures, which can occur in relays, transistors, and other elements.

Conformance to EC Directives 6
• If the I/O Hold Bit is turned ON, the outputs from the PLC will not be
turned OFF and will maintain their previous status when the PLC is
switched from RUN or MONITOR mode to PROGRAM mode. Make sure
that the external loads will not produce dangerous conditions when this
occurs. (When operation stop s for a fatal erro r, including tho se produced
with the FALS(007) instruction, all outputs from Output Unit will be turned
OFF and only the internal output status will be maintained.)
6 Conformance to EC Directives
6-1 Applicable Directives
•EMC Directives
• Low Voltage Directive
6-2 Concepts
EMC Directives
OMRON devices that comply with EC Directives also conform to the related
EMC standards so that they can be more easily built into other devices or the
overall machine. The actual products have been checked for conformity to
EMC standards (see the following note). Whether the products conform to the
standards in the system used by the customer, however, must be checked by
the customer.
EMC-related performance of the OMRON devices that comply with EC Directives will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel on which the OMRON devices are installed.
The customer must, therefore, perform the final check to confirm that devices
and the overall machine conform to EMC standards.
Note The applicable EMC (Electromagnetic Compatibility) standard is EN61131-2.
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 V AC and 75
to 1,500 V DC meet the required safety standards for the PLC (EN61131-2).
6-3 Conformance to EC Directives
The CP1L-EL/EM PLCs comply with EC Directives. To ensure that the
machine or device in which the CP1L-EL/EM PLC is used complies with EC
Directives, the PLC must be installed as follows:
1,2,3... 1. The CP1L-EL/EM PLC must be installed within a control panel.
2. You must use reinforced insulat ion or double insu lation for the DC po wer
supplies used for I/O Units and CPU Units requiring DC power. The output
holding time must be 10 ms minimum for the DC power supply connected
to the power supply terminals on Units requiring DC power.
3. CP1L-EL/EM PLCs complying with EC Directives also conform to
EN61131-2. Radiated emission characteristics (10-m regulations) may
vary depending on the configuration of the control p anel used, other devices connected to the control panel, wiring, and other conditions. You must
therefore confirm that the overall machine or equipment complies with EC
Directives.
