[Wiring Precautions]
!
CAUTION
•
Before wiring the module, confirm the rated voltage and terminal arrangement of the product.
A fire or failure can occur if the power supply connected is different from the rating or wiring is
incorrect.
•
Tighten the terminal screws within the specified torque range.
Undertightening can cause a short circuit or misoperation.
Overtightening can cause a short circuit or misoperation due to damaged screws or module.
•
Ensure that foreign matters such as chips and wire off-cuts do not enter the module.
They can cause a fire, failure or misoperation.
•
Always secure the communication cables connected to the module, e.g. run them in conduits or
clamp them.
Not doing so can damage the module or cables due to dangling, moved or accidentally pulled
cables or can cause misoperation due to cable contact fault.
•
Do not hold the cable part when unplugging the communication cable connected to the module.
Disconnect the cable after loosening the screw in the part connected to the module.
If you pull the cable connected to the module, the module or cable can be damaged or
misoperation can occur due to cable connection fault.
[Startup/Maintenance Precautions]
!
DANGER
•
Do not touch the terminals while power is on.
Doing so can cause an electric shock or misoperation.
•
Before starting cleaning or terminal screw retightening, always switch power off externally in all
phases.
Not doing so can cause a module failure or misoperation.
Undertightening can cause a drop, short circuit or misoperation.
Overtightening can cause a drop, short circuit or misoperation due to damaged screws or module.
!
CAUTION
•
Do not disassemble or modify the module.
Doing so can cause a failure, misoperation, injury or fire.
•
Do not touch the conductive areas and electronic parts of the module.
Doing so can cause the module to misoperate or fail.
•
Do not change any switch setting while power is on.
Doing so can cause a failure or misoperation.
•
The module is made of resin. Do not drop it or subject it to strong impact.
Doing so can damage the module.
•
Always make sure to touch the grounded metal to discharge the electricity charged in the body,
etc., before touching the module.
Failure to do so may cause a failure or malfunctions of the module.
