Power Supply and Ground
Wire the power supply and the ground to their respective terminals. Tighten the screws to a torque of
between 0.49 N·m. After wiring, confirm that the wiring is correct.
Crimp Terminals and Cables
The terminal block uses M3 terminal screws.
Use appropriate crimp terminals for M3 screws, as shown below.
Ground (Earth) Wiring
Always connect a ground wire to the Controller's ground terminal.To avoid grounding problems,
do not share the ground wire with any other devices or wire the ground to the building's steel
framing.
Use a grounding point that is as close as possible and keep the ground wire as short as possible.
