Installation Guidelines

• Ensure the power is disconnected from the FLEX I/O base and the module before installation or removal.
• Mount the module on a standard 35mm DIN rail. Ensure the module is securely seated in the terminal base.
• Maintain proper clearance around the module to allow for adequate ventilation and heat dissipation.
• Use shielded cables for I/O wiring to minimize electromagnetic interference (EMI).
• Ensure all wiring connections are tight and follow local electrical codes for AC circuit protection.
• Handle with care to prevent electrostatic discharge (ESD) damage to the internal circuitry.
