WARNING
Do not attempt to take any Unit apart while the power is being supplied.
Doing so may result in electric shock.
Do not touch any of the terminals or terminal blocks while the power is being
supplied.
Doing so may result in electric shock.
Provide safety measures in external circuits (i.e., not in the Programmable Controller), including the following items, to ensure safety in the system if an
abnormality occurs due to malfunction of the PLC or another external factor
affecting the PLC operation.
Not doing so may result in serious accidents.
• Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits.
• The PLC will turn OFF all outputs when its self-diagnosis function detects any error
or when a severe failure alarm (FALS) instruction is executed. 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 outputs may remain ON or OFF due to deposition or burning of the output

CP1E CPU Unit Hardware User’s Manual(W479)
CautionCaution
Be sure to sufficiently confirm the safety at the destination when you transfer
the program or I/O memory or perform procedures to change the I/O memory.
Devices connected to PLC outputs may incorrectly operate regardless of the operating mode of the CPU Unit.
With an E-type CPU Unit or with an N/NA-type CPU Unit without a Battery, the contents of the DM Area (D) * , Holding Area (H), the Counter Present Values (C), the
status of Counter Completion Flags (C), and the status of bits in the Auxiliary Area (A)
related to clock functions may be unstable when the power supply is turned ON.
*This does not apply to areas backed up to EEPROM using the DM backup function.
If the DM backup function is being used, be sure to use one of the following methods
for initialization.
1. Clearing All Areas to All Zeros
Select the Clear Held Memory (HR/DM/CNT) to Zero Check Box in the Startup
Data Read Area in the PLC Setup.
2. Clearing Specific Areas to All Zeros or Initializing to Specific Values
Make the settings from a ladder program.
If the data is not initialized, the unit or device may operate unexpectedly because of
unstable data.
Execute online edit only after confirming that no adverse effects will be caused
by extending the cycle time.
Otherwise, the input signals may not be readable.
Tighten the screws on the terminal block of the AC power supply section to the
torque specified in the user’s manual.
The loose screws may result in burning or malfunction.
Do not touch the power supply section when power is being supplied or immediately after the power supply is turned OFF.

Caution
Pay careful attention to the polarities (+/-) when wiring the DC power supply.
A wrong connection may cause malfunction of the system.
When connecting the PLC to a computer or other peripheral device, either
ground the 0-V side of the external power supply or do not ground the external
power supply at all.
Otherwise the external power supply may be shorted depending on the connection
methods of the peripheral device. DO NOT ground the 24 V-side of the external
power supply, as shown in the following diagram.

The DM Area (D), Holding Area (H), Counter Completion Flags (C), and Counter
Present Values (C) will be held by the Battery if a Battery is mounted in a CP1EN/NAD- CPU Unit. When the battery voltage is low, however, I/O memory
areas that are held (including the DM, Holding, and Counter Areas) will be unstable.
The unit or device may operate unexpectedly because of unstable data.
Use the Battery Error Flag or other measures to stop outputs if external outputs are performed from a ladder program based on the contents of the DM
Area or other I/O memory areas.
Sufficiently check safety if I/O bit status or present values are monitored in the
Ladder Section Pane or present values are monitored in the Watch Pane.
If bits are set, reset, force-set, or force-reset by inadvertently pressing a shortcut key,
devices connected to PLC outputs may operate incorrectly regardless of the operating mode.
Program so that the memory area of the start address is not exceeded when
using a word address or symbol for the offset.
For example, write the program so that processing is executed only when the indirect
specification does not cause the final address to exceed the memory area by using
an input comparison instruction or other instruction.
If an indirect specification causes the address to exceed the area of the start address,
the system will access data in other area, and unexpected operation may occur.

• Do not pull on the cables or bend the cables beyond their natural limit. Doing either of these may
break the cables.
• Do not place objects on top of the cables or other wiring lines. Doing so may break the cables.
Handling
• To initialize the DM Area, back up the initial contents for the DM Area to backup memory using
one of the following methods.
• Set the number of words of the DM Area to be backed up starting with D0 in the Number of CH
of DM for backup Box in the Startup Data Read Area.
• Include programming to back up specified words in the DM Area to built-in EEPROM by turning
ON A751.15 (DM Backup Save Start Bit).
• Check the ladder program for proper execution before actually running it on the Unit. Not checking
the program may result in an unexpected operation.
• The ladder program and parameter area data in the CP1E CPU Units are backed up in the built-in
EEPROM backup 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 and a memory error
will occur the next time the power supply is turned ON.
• With a CP1E CPU Unit, data memory can be backed up to the built-in EEPROM backup memory.
The BKUP indicator will light on the front of the CPU Unit when backup is in progress. Do not turn
OFF the power supply to the CPU Unit when the BKUP indicator is lit. If the power is turned OFF
during a backup, the data will not be backed up and will not be transferred to the DM Area in RAM
the next time the power supply is turned ON.
• Before replacing the battery, supply power to the CPU Unit for at least 30 minutes and then complete battery replacement within 5 minutes. Memory data may be corrupted if this precaution is
not observed.
• The equipment may operate unexpectedly if inappropriate parameters are set. Even if the appropriate parameters are set, confirm that equipment will not be adversely affected before transferring the parameters to the CPU Unit.
• After replacing the CPU Unit, make sure that the required data for the DM Area, Holding Area, and
other memory areas has been transferred to the new CPU Unit before restarting operation.
• Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in malfunction, fire, or electric shock.
• 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.
• Changing the operating mode of the PLC (including the setting of the startup operating mode).
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• When replacing parts, be sure to confirm that the rating of a new part is correct. Not doing so may
result in malfunction or burning.
CP1E CPU Unit Hardware User’s Manual(W479)

• Do not touch the Expansion I/O Unit Connecting Cable while the power is being supplied in order
to prevent malfunction due to static electricity.
• Do not turn OFF the power supply to the Unit while data is being transferred.
• When transporting or storing Units or Board, static electricity can destroy LSIs or ICs. Cover the
PCBs with a conductive material and maintain the specified storage temperature.
• Do not touch circuit boards or the components mounted to them with your bare hands. There are
sharp leads and other parts on the boards that may cause injury if handled improperly.
• Double-check the pin numbers when assembling and wiring the connectors.
• 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 battery 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.
• Dispose of the product and batteries according to local ordinances as they apply.
• UL standards require that only an experienced engineer can replace the battery. Make sure that
an experienced engineer is in charge of battery replacement. Follow the procedure for battery
replacement given in this manual.
• The following precaution must be displayed on all products that contain a lithium primary battery
(containing at least 6 ppb of perchlorate) and that will be exported to or transported through the
State of California in the USA.
Perchlorate Material - special handling may apply. See
http://www.dtsc.ca.gov/hazardouswaste/perchlorate
A CP1W-BAT01 or CJ1W-BAT01 lithium primary battery (containing at least 6 ppb of perchlorate)
can be mounted in a CP1E-N/NAD- CPU Unit. Display the precaution given above on your
product’s packaging box or shipping box if the product contains a CP1W-BAT01 or CJ1W-BAT01
Battery and is exported to or through the State of California in the USA.
• This product is EMC compliant when assembled in a complete PLC system. Refer to the applicable manual for grounding, cable selection, and any other conditions for EMC compliance.
• This is a Class A product for use in industrial environments. In residential environments it may
cause radio interference, in which case the user may be required to take adequate measures to
reduce interference.
External Circuits
• Always configure the external circuits to turn ON power to the PLC before turning ON power to the
control system. 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 terminals remain ON as a result of internal circuit failures, which can occur in relays, transistors, and other elements.
• 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 stops for a fatal error, including those produced with the FALS instruction, all outputs from PLC will be turned OFF and only the internal output status in the CPU Unit will be maintained.)

Regulations and Standards
Conformance to EC Directives
Applicable Directives
• EMC Directives
• Low Voltage Directive
Concepts
EMC Directives
OMRON devices are electrical components that are designed to be built into equipment and manufacturing systems. OMRON devices that comply with EMC Directives also conform to the related
EMC standards*, so that they can be more easily built into other devices or the overall machine.
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.
* The applicable EMC (Electromagnetic Compatibility) standard is EN61131-2.
Low Voltage Directive
Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75 to 1,500 VDC meet the
required safety standards for the PLC (EN 61131-2).
Conformance to EC Directives
The CP1E PLCs comply with EC Directives. To ensure that the machine or device in which the
CP1E PLC is used complies with EC Directives, the PLC must be installed as follows:
• The CP-series PLC must be installed within a control panel.
• CP-series 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 panel
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.
• A SYSMAC CP-series PLC is a class A product (for an industrial environment). In residential
areas it may cause radio interference, in which case the user may be required to take adequate
measures to reduce interference.
