[Design Precautions]
[Design Precautions]
WARNING
●When a communication failure occurs in the network, data in the master module are held. Check the
signals indicating the data link status of each station and configure an interlock circuit in the program
to ensure that the entire system will operate safely.
●Outputs may remain on or off due to a failure of the module. Configure an external circuit for
monitoring output signals that could cause a serious accident.
CAUTION
●Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.
●During control of an inductive load such as a lamp, heater, or solenoid valve, a large current
(approximately ten times greater than normal) may flow when the output is turned from off to on.
Therefore, use a module that has a sufficient current rating.
●The main switch, the switches of the subsequent circuits, the cable cross sections and the fuse
protection have to be configured according to IEC 61010. The current demand must be calculated
separately for each slave station.
●In the case of modules without fused external devices, all cables to the connected devices must be
fused corresponding to their conductor cross-section (DIN VDE 0298 Part 4).
●To meet UL-specifications in accordance with UL 248-14, a UL-certified automatic fuse (e.g. ABB
Type S201-B16) or a 10A fuse with a medium time-lag (e.g. ESKA Part No.522.227) must be used.
●All connections of the slave stations are protected against voltage pulses and overcurrent in
accordance with IEC 61131-2, Zone B. The operator has to decide whether additional overvoltage
protection according to IEC 62305 is required. Voltages that exceed 30V may cause the destruction
of couplers and I/O modules.
WARNING Indicates that incorrect handling may cause hazardous conditions, resulting in
death or severe injury.
CAUTION Indicates that incorrect handling may cause hazardous conditions, resulting in
minor or moderate injury or property damage.

the system against unauthorized access, denial-of-service (DoS) attacks, computer viruses, and other
cyberattacks from external devices via the network, take appropriate measures such as firewalls,
virtual private networks (VPNs), and antivirus solutions.
WARNING
●Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.
CAUTION
●Use the module in an environment that meets the general specifications in this manual. Failure to do
so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.
●Do not directly touch any conductive parts and electronic components of the module. Doing so can
cause malfunction or failure of the module.
●Securely connect the cable connectors. Poor contact may cause malfunction.
●According to IEC 61340-5-1 and IEC 61340-5-2, ensure that the static electricity is discharged from
the human body before handling the module or connection cables. Failure to do so may cause the
module to fail or malfunction.
●Note, during insulation test, that the test voltage between 24V and 24G must not exceed 28.8V within
one channel. In addition, test voltages for all other connection points must not exceed 500V.
WARNING
●Shut off the external power supply (all phases) used in the system before wiring. Failure to do so may
result in electric shock or cause the module to fail or malfunction.
●Do not use the shield for equipotential bonding. Doing so can cause a serious accident.
[Precautions for using NZ2FTS2-4A]
●Be sure to supply all I/O cables from the same power source.

[Wiring Precautions]
CAUTION
●Individually ground the FG terminal of the programmable controller with a ground resistance of 100
ohms or less. Failure to do so may result in electric shock or malfunction.
●Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly. Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire
or failure.
●Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can
cause a fire, failure, or malfunction.
●Place the cables in a duct or clamp them. If not, dangling cables may swing or inadvertently be pulled,
resulting in malfunction or damage to modules or cables. In addition, the weight of the cables may put
stress on modules in an environment of strong vibrations and shocks.
●Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction
due to noise.

[Wiring Precautions]
CAUTION
●For the cable with connector, hold the connector part of the cable. Pulling the cable connected to the
module may result in malfunction or damage to the module or cable.
●When an overcurrent caused by an error of an external device or a failure of the programmable
controller flows for a long time, it may cause smoke and fire. To prevent this, configure an external
safety circuit, such as a fuse.
●Mitsubishi programmable controllers must be installed in control panels. Wiring and replacement of a
module must be performed by qualified maintenance personnel with knowledge of protection against
electric shock. For wiring methods, refer to "INSTALLATION AND WIRING" in this manual.
●To achieve specification according to UL 248-14, use a UL-approved Type-B automatic circuit breaker
(e.g. ABB Type S201-B16) or a fuse with a maximum of 10A protection (e.g. ESKA Part No.522.227).
If an improperly rated circuit protection is used, equipment may become damaged.
●Do not use auxiliary power supplies as well as signal inputs and outputs for supplying power to slave
stations. Doing so may cause a failure due to an overcurrent.
●If the power supply and ambient temperature exceed 8A and 55, use 1.5wire for the power
supply wiring. Failure to do so may cause a failure.
[Precautions for using NZ2FTS-60DA4]
●Terminals S 0-, S 1-, S 2-, and S 3- are connected to the supply potential (24G). Configure a circuit so
that no compensation current will flow through the module. Failure to do so may cause a failure of the
module.
[Precautions for using NZ2FTS2-4A]
●Ensure that the input frequency does not exceed 65Hz and the switching frequency does not exceed
15Hz. Failure to do so may cause a failure of the module.
●Be sure to install a slow fuse up to 4A at the input. Failure to do so may cause a failure of the module.
●When using the module in an environment where there is a risk of explosion, observe the following
precautions.
(1) Install the module in an environment without condensation, corrosives or conductive dust.
(2) If the switching voltage or input voltage exceeds 63V, prepare a transient protection device that
limits the peak voltage to 500V or less during transitions.
[Precautions for using NZ2FTS3-4R]
●When using the module in an environment where there is a risk of explosion, observe the following
precautions.
