[Wiring Precautions]
CAUTION
• 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.
Pulling the cable connected to the module may result in malfunction or damage to the module or
cable.
• Individually ground the shielded cables on the encoder side (relay box) with a ground resistance
of 100
or less.
Failure to do so may cause 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.
[Startup and Maintenance Precautions]
WARNING
• Do not touch any terminal while power is on.
Doing so will cause electric shock or malfunction.
• Shut off the external power supply (all phases) used in the system before cleaning the module or
retightening the connector screws or module fixing screws.
Failure to do so may result in electric shock or 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.
CAUTION
• Do not disassemble or modify the module.
Doing so may cause failure, malfunction, injury, or a fire.
• Shut off the external power supply (all phases) used in the system before mounting or removing
the module.
Failure to do so may cause the module to fail or malfunction.
• After the first use of the product, do not mount/remove the module to/from the base unit more
than 50 times (IEC 61131-2 compliant).
Exceeding the limit of 50 times may cause malfunction.
• Before handling the module, touch a conducting object such as a grounded metal to discharge
the static electricity from the human body.
Failure to do so may cause the module to fail or malfunction.
