[Wiring Precautions]
WARNING
Shut off the external power supply for the system in all phases before installation and wiring.
After wiring, attach the included terminal cover to the module before turning it on for operation.
Failure to do so may result in electric shock.
[Wiring Precautions]
CAUTION
Use applicable solderless terminals and tighten them within the specified torque range. If any spade
solderless terminal is used, it may be disconnected when the terminal screw comes loose, resulting in
failure.
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.
Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100mm (3.94 inches) or more between them. Failure to do so may result in
malfunction due to noise.
Place the cables in a duct or clamp them. If not, dangling cables may swing or inadvertently be pulled,
resulting in damage to the module or cables or malfunction due to poor connection.
Tighten the terminal screw within the specified torque range.
Undertightening can cause short circuit, fire, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
Tighten the connector screws within the specified torque range. Undertightening can cause short circuit,
fire, or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit,
fire, or malfunction.
Install the connector to the module securely. Failure to do so may cause malfunction.
When disconnecting the cable from the module, do not pull the cable by the cable part. For a cable with
connector, hold the connector by hand and pull it out. For a cable connected to a terminal block, loosen
the terminal block screws first before removing the cable. Failure to do so may result in malfunction and
damage to the module or cable.
Before connecting the cables, check the type of interface to be connected. Connecting or erroneous
wiring to the wrong interface may cause failure to the module and external devices.
Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can
cause a fire, failure, or malfunction.
