◆ Prevent metal filings and wire ends from dropping into The ventilation holes of the PLC during
installation. Otherwise it may result in fire, fault and malfunction.
◆
Ensure there are no foreign matters on 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.
Wiring
=GXTOTM
◆
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.

◆ Prevent dropping metal filings and wire ends drop into ventilation holes of the PLC at wiring.
Failure 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.
◆
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 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 system anti-interference ability.
