■ Safety Levels and De󶍾nitions
WARNING
: Indicates that failure to comply with the notice may result in severe
personal injuries or even death.
CAUTION
: The“CAUTION”sign indicates that failure to comply with the notice may result
in minor or moderate personal injury or damage to the equipment.
Please keep this guide well so that it can be read when necessary and forward this guide to the
end user.
Control system design
WARNING
◆ Provide a safety circuit outside the PLC so that the control system can still work safely once
external power failure or PLC fault occurs.
◆ Add a fuse or circuit breaker because the module may smoke or catch 󶍾re due to long-time
overcurrent caused by operation above rated current or load short-circuit.
CAUTION
◆An emergency stop circuit, a protection circuit, a forward/reverse operation interlocked circuit,
and a upper position limit and lower position limit interlocked circuit must be set in the
external circuits of PLC to prevent damage to the machine.
◆To ensure safe operation, for the output signals that may cause critical accidents, please design
external protection circuit and safety mechanism.
◆ Once 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 cannot 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.

Installation
WARNING
◆Installation must be carried out by the specialists who have received the necessary electrical
training and understood enough electrical knowledge.
◆Disconnect all external power supplies of the system before removing/installing the module.
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, 󶍾re 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.
CAUTION
◆ Prevent metal 󶍾lings and wire ends from dropping into ventilation holes of the PLC during
installation. Failure to comply may result in 󶍾re, fault and malfunction.
◆Ensure there are no foreign matters on ventilation surface. Failure to comply may result in poor
ventilation, which may cause 󶍾re, fault and malfunction.
◆Ensure the module is connected to the respective connector securely and hook the module
󶍾rmly. Improper installation may result in malfunction, fault or fall-o󶍽.
Wiring
WARNING
◆Wiring must be carried out by personnel who have received the necessary electrical training
and 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.

4
CAUTION
◆ Prevent dropping metal 󶍾lings and wire ends drop into ventilation holes of the PLC at wiring.
Failure to comply may result in 󶍾re, fault and malfunction.
◆ The external wiring speci󶍾cation 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 su󶎀cient diameter and connect
the cables to ground reliably.
◆Ensure that all cables are connected to the correct interface. Failure to comply may result in
module and external equipment fault.
◆ Tighten bolts on the terminal block in the speci󶍾ed torque range. If the terminal is not tight,
short-circuit, 󶍾re or malfunction may be caused. If the terminal is too tight, fall-o󶍽, short-circuit,
󶍾re or malfunction may be caused.
◆If the connector is used to connect with external equipment, perform correct crimping or
welding with the tool speci󶍾ed by manufacturer. If connection is in poor contact, short-circuit,
󶍾re 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. Remove it before operation for 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 system anti-interference ability.
Operation and Maintenance
WARNING
◆ Maintenance & inspection must be carried out by quali󶍾ed personnel.
◆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 communication wirings. Failure to comply may result in electric shock or malfunction.
CAUTION
◆ Get with the guide and ensure safety before online modi󶍾cation, forcible output, and RUN/
STOP operation.
◆Disconnect the power supply before installing/removing the extension card.
Disposal
CAUTION
◆Dispose of the product as industrial waste.

of the cable between the devices must not exceed 100 meters. Exceeding this
length will attenuate the signal and a󶍽ect communication.
■Technical requirements:
100% continuity test, no short circuit, open circuit, misalignment and poor contact.
Use a shielded cable as the EtherCAT bus for network data transmission, with the
following recommended speci󶍾cations:

NOTE
To protect the communication cable from any tension and to ensure
communication stability, 󶍾x the cable end which is near the device
before EtherCAT communication.
Con󶍾guration and use
1) When using this branch device, run all EtherCAT slaves (including the two
stations of this branch device) with an alias, so that an abnormal branch will
not a󶍽ect the others.
2) The data 󶍿ow priority of a 6-way branch device interface is X2>X3>X4>X5>X6, that is,
any slave on the X2 branch has priority over all slaves on the X3 branch.
3) The DC mode is enabled by default. That is, the branch device has been con󶍾gured
as an EtherCAT slave in DC mode.
4) The branch device allows cascade, and the allowable number of nodes is not
restricted by the device.
5) Each branch device occupies two EtherCAT slave station numbers.
Fault Indication and Solutions

indicator and take corresponding measures:
