[Wiring Instructions]
 Connectors for external connection must be crimped or pressed with the tool specified by the
manufacturer, or must be correctly soldered.
If the connection is incomplete, it may cause the module to short circuit, catch fire, or
malfunction.
 Shut off the external power supply for the system in all phases before connecting the AUI cable.
 When connecting a cable with connector to the module, connect the connector part to the
module securely.
 Make sure to place the communication and power cables to be connected to the module in a
duct or fasten them using a clamp. If the cables are not placed in a duct or fastened with a
clamp, their positions may be unstable or moved, and they may be pulled inadvertently.
This may damage the module and the cables or cause the module to malfunction because of
faulty cable connections.
 Tighten the terminal screws using the specified torque. If the terminal screws are loose, it may
cause the module to short-circuit, malfunction or fall off. If the terminal screws are tightened
excessively, it may damage the screws and cause the module to short-circuit, malfunction or fall
off.
 When disconnecting the cable from the module, do not pull the cable by the cable part.
For the cable with connector, hold the connector part of the cable.
For the cable connected to the terminal block, loosen the terminal screw.
Pulling the cable connected to the module may result in malfunction or damage to the module or
cable.
 Prevent foreign matter such as dust or wire chips from entering the module.
Such foreign matter can cause a fire, failure, or malfunction.
 A protective film is attached to the top of the module to prevent foreign matter, such as wire
chips, from entering the module during wiring.
Do not remove the film during wiring.
Remove it for heat dissipation before system operation.
 Correctly solder coaxial cable connectors. Incomplete soldering may result in malfunction.
