Safety Information and Precautions

Safety information and precautions are identified into two grades: Warning and Caution. Please make
sure to operate properly with adequate safety assurance.
: Indicates the improper operation which, if not avoided, may cause death or serious injury;
WARNING
: Indicates the improper operation which, if not avoided, may cause moderate or minor
CAUTION
injury, as well as equipment damage.
In some cases, even failure to follow "Cautions" may also lead to serious consequences. Please make
sure to follow both warnings and cautions; otherwise, it may cause death or serious injury, as well as
product and relevant equipment and system damage.
Please keep this guide well so that it can be read when necessary and forward this guide to the end user.
During control system design
◆ Provide a safety circuit outside the PLC so that the control system can still work safely once external
WARNING
power failure or PLC fault occurs.
Add a fuse or circuit breaker because the module may smoke or catch fire due to long-time
◆
overcurrent caused by operation above rated current or load short-circuit.
An emergency stop circuit, a protection circuit, a forward/reverse operation interlocked circuit, and a
◆
CAUTION
upper position limit and lower position limit interlocked circuit must be set in the external circuits of the
PLC to prevent damage to the machine.
To ensure safe operation, for output signals related to critical accidents, please design external
◆
protection circuit and safety mechanism;
◆ Once the PLC CPU detects abnormality in the system, all outputs may be closed; however, when a
fault occurs in the controller circuit, the output may not be under control. Therefore, it is necessary to
design an appropriate external control circuit to ensure normal operation;
◆ If the PLC's output units such as relays or transistors are damaged, the output may fail to switch
between ON and OFF states according to the commands;
The PLC is designed to be used in indoor electrical environment (overvoltage category II). The
◆
power supply must have a system-level lightning protection device, assuring that overvoltage due to
lightning shock can't be applied to the PLC's power supply input terminals, signal input terminals and
output terminals and so forth, so as to avoid damage to the equipment.
During installation
Installation must be carried out by the specialists who have received the necessary electrical training
◆
WARNING
and understood enough electrical knowledge.
Disconnect all external power supplies of the system before module assembly/disassembly and wiring.
◆
Failure to do so may result in electric shock, module fault or malfunction.
Do not use the PLC where there are dust, oil smoke, conductive dust, corrosive or combustible gases,
◆
or exposed to high temperature, condensation, wind & rain, or subject to vibration and impact. Electric
shock, fire and malfunction may also result in damage or deterioration to the product.
The PLC is open-type equipment that must be installed in a control cabinet with lock (cabinet housing
◆
protection > IP20). Only the personnel who have received the necessary electrical training and
understood enough electrical knowledge can open the cabinet.
◆ Prevent metal filings and wire ends from dropping into ventilation holes of the PLC during installation.
CAUTION
Otherwise it may result in fire, fault and malfunction.
Ensure there are no foreign matters on the ventilation surface. Failure to comply may result in poor
◆
ventilation, which may cause fire, fault and malfunction.
◆ Ensure the module is connected to the respective connector securely and hook the module firmly.
Improper installation may result in malfunction, fault or fall-off.
During wiring
Wiring must be carried out by personnel who have received the necessary electrical training and
◆
WARNING
understood enough electrical knowledge.
◆ Disconnect all external power supplies of the system before wiring. Failure to comply may result in
electric shock, module fault or malfunction.
Install the terminal cover attached to the product before power-on or operation after wiring is
◆
completed. Failure to comply may result in electric shock.
◆ Perform good insulation on terminals so that insulation distance between cables will not reduce after cables
are connected to terminals. Failure to comply may result in electric shock or damage to the equipment.
Prevent metal filings and wire ends from dropping into ventilation holes of the PLC at wiring. Failure
◆
CAUTION
to comply may result in fire, fault and malfunction.
The external wiring specification and installation method must comply with local regulations. For
◆
details, see the wiring section in this guide.
To ensure safety of equipment and operator, use cables with sufficient diameter and connect the
◆
cables to ground reliably.
◆ Wire the module correctly after making clear of the connector type. Failure to comply may result in
module and external equipment fault.
Tighten bolts on the terminal block in the specified torque range. If the terminal is not tight, short-
◆
circuit, fire or malfunction may be caused. If the terminal is too tight, fall-off, short-circuit, fire or
malfunction may be caused.
If the connector is used to connect with external equipment, perform correct crimping or welding with
◆
the tool specified by manufacturer. If connection is in poor contact, short-circuit, fire or malfunction
may be caused.
◆ A label on the top of the module is to prevent foreign matters entering the module. Do not remove the
label during wiring. Remember to remove it before system operation, facilitating ventilation.
Do not bundle control wires, communication wires and power cables together. They must be run with
◆
distance of more than 100 mm. Otherwise, noise may result in malfunction.
Select shielded cable for high-frequency signal input/output in applications with serious interference
◆
so as to enhance immunity to interference of the system.
During maintenance & inspection
Maintenance & inspection must be carried out by personnel who have the necessary electrical
◆
WARNING
training and experience.
◆ Do not touch the terminals while the power is on. Failure to comply may result in electric shock or
malfunction.
Disconnect all external power supplies of the system before cleaning the module or re-tightening
◆
screws on the terminal block or screws of the connector. Failure to comply may result in electric
shock.
Disconnect all external power supplies of the system before removing the module or connecting/
◆
removing the communication wirings. Failure to comply may result in electric shock or malfunction.
Get acquainted with the guide and ensure safety before online modification, forcible output, and RUN/
◆
CAUTION
STOP operation.
◆ Disconnect the power supply before installing/removing the extension card.
At disposal
Treat scrapped module as industrial waste. Dispose the battery according to local laws and
◆
CAUTION
regulations.

*1. Shielded cables need to be used.
*2. When the two-wire system is used in wiring, the INB and INb channels need to be
shorted. In this case, resistors on the cable affect the measurement value.
*3. Cables with low wire resistance in which there is no resistance difference among the
three wires need to be used.
*4 The module should be mounted on a well-grounded metal bracket, and the metal
shrapnel at the bottom of the module must be in good contact with the bracket.

■ Wiring Precautions

Do not bundle the cable together with AC cable, main lines, high voltage cable and so
forth; otherwise, it may result in an increased noise, surge and induction.
Apply single-point grounding for the shielding of shielded cable and solder sealed cable.
Tubed and solderless crimp terminal cannot be used with a terminal block. It is
recommended that a marking sleeve or insulation sleeve be used to cover the cable
connector part of the crimp terminals.
