◆ 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 specication 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 sucient 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 specied 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 specied 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
◆ Maintenance & inspection must be carried out by qualied 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.
◆ Get with the guide and ensure safety before online modication, forcible output, and RUN/
STOP operation.
◆ Disconnect the power supply before installing/removing the extension card.
