[Wiring Precautions]
Completely turn off the externally supplied power used in the system when
installing or placing wiring.
Failure to do so may cause electric shocks or damage the product.
Always connect the FG terminals to the ground using class D (class 3) or
higher grounding exclusively designed for programmable controller.
Failure to do so may cause malfunctions.
When connecting cables to the terminal block for external power supply,
check the rated voltage and terminal layout of the product for correct wiring.
Connecting a power supply that is different from the rating or incorrectly
wiring the product could result in fire or damage.
Tighten the terminal screws with the specified torque.
If the terminal screws are loose, it could result in short circuits, fire, or
erroneous operation.
Solder coaxial cable connectors properly. Incomplete soldering may result in
malfunctioning.
Be sure there are no foreign substances such as sawdust or wiring debris
inside the module.
Such debris could cause fires, damage, or erroneous operation.
The module has an ingress prevention label on its top to prevent foreign
matter, such as wire offcuts, from entering the module during wiring.
Do not peel this label during wiring.
Before starting system operation, be sure to peel this label because of heat
dissipation.
Make sure to place the communication and power cables into a duct or
fasten them using a clamp. Failure to do so may damage the module or
cables by pulling a dangling cable inadvertently or cause the module to
malfunction due to bad connection.
When disconnecting the communication and power cables from the module,
do not pull a cable part by hand.
When disconnecting a cable with a connector, hold the connector connected
to the module by hand and pull it out to remove the cable. When
disconnecting a cable connected to a terminal block, loosen the screws on
the terminal block first before removing the cable. If a cable is pulled while
being connected to the module, it may cause the module to malfunction or
damage the module and cables.
