[Wiring Precautions]
[Starting and Maintenance Precautions]
CAUTION
●
Check the rated voltage and terminal layout before wiring to the module, and
connect the cables correctly. Applying a voltage or inputting a current that
exceeds the absolute maximum input of the module, connecting a power
supply with a different voltage rating, or wiring the cables incorrectly may
cause a fire or failure.
●
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.
●
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 control lines or communication cables together with the
main circuit lines or power cables. 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. Loosen the screws of connector before disconnecting the cable.
Failure to do so may result in damage to the module or cable or malfunction
due to poor contact.
WARNING
●
Do not touch any terminal while power is on. Doing so will cause electric
shock or malfunction.
●
Shut off the external power supply for the system in all phases before
cleaning the module or retightening the terminal screws or module mounting
screws. Failure to do so may cause the module to fail or malfunction.
Undertightening can cause drop of the screw, short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short
circuit, or malfunction.
