Installation Guidelines
Ensure the PLC system power is disconnected before installing or removing the module from the I/O base.
Verify that the module is securely seated in the designated slot of the TI 505 rack to ensure proper backplane communication.
Use appropriate wire gauges for terminal connections and ensure all screws are tightened to prevent loose contacts.
Maintain proper spacing for ventilation to prevent overheating, as relay modules can generate heat under continuous load.
Follow standard ESD (Electrostatic Discharge) precautions when handling the module to protect internal components.
