• When removing the communication cable from the module, do not pull the cable. When
removing the cable with a connector, hold the connector on the side that is connected to the
modules.
Pulling the cable that is still connected to the module may cause malfunction or damage to the
module or cable.
• Always ground the shielded cable on the encoder side (relay box).
Otherwise, malfunction may occur.
• When wiring, be sure to verify the rated voltage of the product as well as the terminal layout. Fire
or failure may result if incorrect voltage is input or incorrect wiring is performed.
• Connecting terminals with incorrect voltage may result in malfunction or mechanical failure.
[STARTUP/MAINTENANCE PRECAUTIONS]
• Do not disassemble or modify the module.
Doing so could cause failure, malfunction, injury or fire.
• Be sure to shut off all phases of the external power supply used by the system before mounting
or removing the module.
Not doing so may cause failure or malfunction of the module.
• Do not mount/remove the module onto/from the base unit more than 50 times (IEC61131-2-
compliant), after the first use of the product. Failure to do so may cause the module to
malfunction.
• Do not touch the connector while the power is on.
Doing so may cause malfunction.
• Be sure to shut off all phases of the external power supply before cleaning or retightening the
terminal screws or module fixing screws.
Not doing so may cause failure or malfunction of the module.
If the screws are loose, it may cause the module to fallout, short circuits, or malfunction.
If the screws are tightened too much, it may cause damages to the screws and/or the module,
resulting in the module falling out, short circuits or malfunction.
