Precautions for Safe Use
Power Supply and Wiring
• Never connect AC power to this product. Connecting an AC power source may cause a mal-
function.
• The recommended power supply is S8VS-
24 (made by OMRON) or S8VK-G-
24
(made by OMRON).
• Keep the power supply wires as short as possible (Max.10 m).
• Use the cables and crimping terminals with the specified dimensions.
Do not directly connect an electric wire to the terminal lock that is simply twisted.
• Recommended wire size: AWG16 to 13 (1.31 to 2.63 mm
2
)
• Terminal screw: M4 (Tightening torque: 1.4 N·m)
• Crimping Terminal
• After wiring, replace the terminal cover.
Ground
• The controller power circuit is not insulated from its internal circuit.
• When grounding the 24 V DC power supply’ s positive terminal, do not ground the controller’
s FG terminal or the PLC’ s FG terminal. [
,
] Since the PC’ s shell and the SG (0 V) are
connected inside the PC, current would run through the route shown in the figure below and
cause burnout.
• As in the case with a PC, you can safely ground the controller’ s FG terminal without a prob-
lem when there is no possibility that the SG (0 V) and the FG will short-circuit. For information
about the PLC wiring, check the specifications of your PLC before wiring.
• Be sure to use a pedestal when connecting a camera to the controller. [
] As the shell of the
camera is the SG (0 V), it can cause short-circuiting between the SG (0 V) and the FG if a
pedestal is not used.
• To avoid receiving an electric shock when grounding a positive terminal, do not touch the SG
(0 V) (camera, power supply terminal).
