Wiring
• Always connect a power supply that meets the given specifications.
Connecting an inappropriate power supply may cause fires.
• Wiring must be performed by qualified personnel.
Incorrect wiring may cause fires, product failure, or malfunctions.
• Do not accidentally leave foreign matter such as wire chips in the Module when wir-
ing.
This may cause fires, failures, and malfunctions.
• Always ground the FG terminal to a ground resistance 100 Ω or less.
Failure to ground the 260IF Module may result in electrical shocks or malfunctioning.
Select, separate, and lay external cables correctly.
• Consider the following items when selecting the I/O signal lines (external cables) to
connect the 260IF Module to external devices.
• Mechanical strength
• Noise interference
• Wiring distance
• Signal voltage, etc.
• Separate the I/O signal lines from the power lines both inside and outside the con-
trol panel to reduce the influence of noise from the power lines.
If the I/O signal lines and power lines are not separated properly, malfunctioning may result.
