4-2 Wiring

When performing wiring, observe the following points:
1) Warning for wiring
Never touch any part of charged circuits as terminals and exposed metal portion while the power is turned ON.
It may result in an electric shock to the operator.
Turn OFF the power before mounting, dismounting, wiring, maintaining or checking, otherwise, electric shock, erratic
operation or troubles might occur.
Place the emergency stop circuit, interlock circuit or the like for safety outside the PLC. A failure of PLC might break or
cause problems to the machine.
2) Cautions for wiring and mounting
Follow the directions of the operating instructions when mounting the product. If mounting is improper, the product might
drop or develop problems or erratic operations.
Be sure to install the electrical wiring correctly and securely, observing the operating instructions and manual.
Wrong or loose wiring might cause fire, accidents, or failure.
Select a wire size to suit the applied voltage and carrying current, and carry out wiring according to the operating
instructions and manual. Poor wiring might cause fire, erratic operation or failure.
Periodically make sure the terminal screws and mounting screws are securely tightened. Operation at a loosened status
might cause fire or erratic operation.
Before touching the PLC, touch any metallic object which is connected to the ground to discharge static electricity.
Excessive static electricity may cause malfunction or fault.
3) Cautions for checking wiring
Sufficiently make sure of safety before program change, forced output, starting, stopping or anything else during a run.
Engage the loader connector in a correct orientation, otherwise, an erratic operation might occur.
4) Cautions after wiring
Remove the dust-cover seals of modules after wiring, otherwise, fire, accidents, failure or fault might occur.
