[Wiring Precautions]
● Shut off the external power supply (all phases) used in the system before wiring. Failure to do so may
result in electric shock or cause the module to fail or malfunction.
[Wiring Precautions]
● Ground the shield cable for the pulse input on the encoder side (relay box) with a ground resistance of
100 or less. Failure to do so may cause malfunction.
● Individually ground the FG terminal of the programmable controller with a ground resistance of 100
or less. Failure to do so may result in electric shock or malfunction.
● Check the rated voltage and terminal layout before wiring to the module, and connect the cables
correctly. Connecting a power supply with a different voltage rating or incorrect wiring may cause a fire
or failure.
● Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can
cause a fire, failure, or malfunction.
● Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled,
resulting in damage to the module or cables or malfunction due to poor contact.
● Do not install the communication cables together with the main circuit lines or power cables. Keep a
distance of 100mm or more between them. Failure to do so may result in malfunction due to noise.
● Do not install the control lines together with the main circuit lines or power cables. Keep a distance of
150mm or more between them. Failure to do so may result in malfunction due to noise.
● 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.
● When an overcurrent caused by an error of an external device or a failure of the programmable
controller flows for a long time, it may cause smoke and fire. To prevent this, configure an external
safety circuit, such as a fuse.
● Connectors for external devices must be crimped with the tool specified by the manufacturer, or must
be correctly soldered. Securely connect the connector to the module.
● Mitsubishi programmable controllers must be installed in control panels. Wiring and replacement of a
module must be performed by qualified maintenance personnel with knowledge of protection against
electric shock. For wiring methods, refer to "INSTALLATION AND WIRING" in this manual.
