22 CP1E CPU Unit Hardware User’s Manual(W479)
• 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.
• 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/NA
D - 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 applica-
ble 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, tran-
sistors, 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 out-
puts from PLC will be turned OFF and only the internal output status in the CPU Unit will be main-
tained.)
