Installation Guidelines
- Ensure the controller and I/O power are disconnected before installing or removing the module to prevent electrical shock or damage to the backplane.
- Mount the module on a standard DIN rail or panel mount as per CompactLogix system requirements.
- Use appropriate wire gauges (22-14 AWG solid or 22-16 AWG stranded) and ensure all connections are tightened to the manufacturer's torque specifications.
- Maintain proper clearance for ventilation to prevent overheating, as the module relies on passive cooling.
- Route signal wiring away from high-voltage power cables and sources of electromagnetic interference (EMI) to ensure signal integrity.
- Follow standard ESD (Electrostatic Discharge) handling procedures when touching the module circuitry.
