Operating Environment Precautions4
!Caution After programming (or repr ogrammi ng) using the IOWR instruction, confir m
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 CP1H CPU Units automatically back up the user program and parameter
data to flash memor y when these are written to the CPU Unit. I/O memory
(including the DM Area , counter present values and Completion Flags, an d
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 ba ttery. If there is a batter y error, the contents of these
areas may not be accurate af ter a power interruption. If the con tents of 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.

• 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. Doing so may break the cables.
• When replacing p arts, be sure to confi rm that the rating of a new par t is
correct. Not doing so may result in malfunction or burning.
• Before touching the Unit, be su re to firs t to uc h a grounde d m etal li c obj ec t
in order to discharge a ny static buildup. Not doing so may result in malfunction or damage.
• Do not touch the Expansion I/ O Unit Conn ec tin g Cable while the power is
being supplied in order to prevent malfunction due to static electricity.
• Do not turn O FF the power supply to the Uni t while data is being tran sferred.
• When transporting or storing the product, cover the PCBs with electrically
conductive materials to prevent LSIs and ICs from being damaged by
static electricity, and also keep the product within the specified storage
temperature range.
• Do not touch the mounted par ts or the rear surface of PCBs because
PCBs have sharp edges such as electrical leads.
• Double-check the pin numbers when assembling an d wiring t he connectors.
• Wire correctly according to specified procedures.
• Do not connect pin 6 (+5V) on the RS-232C Opti on Board 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 conne cting cables specified in this manual to connect
the Units. Using commerc ially avai lable RS-232C computer cables may
cause failures in external devices or the CPU Unit.
xxvi
Application Precautions5
• Check that data link tables an d parameters are p roperly set before star ting operation. Not doing so may result in un expe cted operation. Even if
the tables and parameters are properly set, confirm that no adverse
effects will occur in the system before running or stopping data links.
• Transfer a routing table to the CPU Unit only after confirming that no
adverse effects will be caused by restarting CPU Bus Units, which is automatically done to make the new tables effective.
• The user program and param eter a r ea data i n th e C PU Uni t i s backed up
in the built-in flash memory. The BKUP indicator will light on the fr ont of
the CPU Unit when the backup operation i s in progress. Do not tur n 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 accessed. Doin g so may cor rupt the data in the Memory Cassette. The 7-segment LED will light to indicate writing progress while the
Memory Cassette is being accessed. Wait for the LED display to go out
before turning OFF the power supply to the PLC.
• Before replacing the batter y, supply power to the CPU Unit for at least 5
minutes and then complete battery repla cement within 5 minutes of tu rn
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 Units, Spec ia l I/O
Units, and CPU Bus Units: AWG22 to AWG18 (0.32 to 0.82 mm
• UL standards required that batteries be replaced only by experienced
technicians. Do not allow unqualified pe rsons 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 s ubject the
battery to str ong shocks or defor m the barr y by apply ing pressu re. Doing
any of these may result in leakage, ruptur e, heat gene ration, or ig nit ion of
the battery. Dispose of any battery that has been dropped on the f loor 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 turne d
ON before the power to the control system is turned ON. If the PLC power
supply is turned ON afte r the c ontrol power su pply, temporary errors may
result in control system signals bec ause the outpu t ter minals on DC Output Units and other U nits will mo mentar ily tur n ON when power is tur ned
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.
• 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 conditi ons when this
occurs. (When operation stops for a fatal error, including those produced
with the FALS(007) instruction, all outputs from Outpu t Unit will be turned
OFF and only the internal output status will be maintained.)

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.

6-4Relay Output Noise Reduction Methods
The CP1H PLCs conforms to the Commo n Emissi on Stand ards (EN61131- 2)
of the EMC Directives. However, noise generated by relay output switching
may not satisfy these Standards. In such a ca se, a noise filter must be connected to the load side o r other appropriate counter measures must be provided external to the PLC.
Countermeasures taken to satisfy the standards vary depending on the
devices on the load side, wiring, co nfi guration of mac hi nes, etc . Following are
examples of countermeasures for reducing the generated noise.
Countermeasures
Countermeasur es are not required if the f requency of load switching for the
whole system with the PLC included is less than 5 times per minute.
Countermeasures are required if the frequency of load switching for the whole
system with the PLC included is more than 5 times per minute.
NoteRefer to EN61131-2 for more details.
Countermeasure Examples
When switching an inductive load, co nne ct a n su r ge pr ot ec tor, diodes, etc., in
parallel with the load or contact as shown below.

a time lag between the moment the circuit is opened and the moment the load
is reset.
If the supply voltage is 24 or 48 V , insert
the surge protector in parallel with the
load. If the supply voltage is 100 to
200 V, insert the surge protector
between the contacts.
The capacitance of the c apacitor must
be 1 to 0.5 µF per contact current of
1 A and resistance of the resistor must
be 0.5 to 1 Ω per contact v oltag e of 1V.
These values, however, vary with the
load and the characteristics of the
relay. Decide these values from experiments, and take into consideration that
the capacitance suppresses spark discharge when the contacts are separated and the resistance limits the
current that flows into the load when
the circuit is closed again.
The dielectric strength of the capacitor
must be 200 to 30 0 V. If the circ uit i s an
AC circuit, use a capacitor with no
polarity.

This time lag, betw een the m om ent the
circuit is opened and the moment the
load is reset, caused by this method is
longer than that caused by the CR
method.
YesYesThe varistor method prevents the impo-
sition of high voltage between the contacts by using the constant voltage
characteristic of the varistor. There is
time lag between the moment the cir-
Inductive
load
cuit is opened and the moment the load
is reset.
If the supply voltage is 24 or 48 V , insert
the varistor in parallel with the load. If
the supply voltage is 100 to 200 V,
insert the varistor between the contacts.
The reversed dielectric strength value
of the diode must be at least 10 times
as large as the circuit voltage value.
The forward current of the diode must
be the same as or larger than the load
current.
The reversed dielectric strength value
of the diode may be two to three times
larger than the supply voltage if the
surge protector is applied to electronic
circuits with low circuit voltages.
