Installation Guidelines
- Ensure the ControlLogix chassis is properly grounded before installing the module.
- The 1756-L73S must be installed in a standard ControlLogix chassis; ensure the module is fully seated and the locking latch is engaged.
- Always power down the chassis backplane before inserting or removing the processor module to prevent electrical damage.
- Maintain adequate clearance around the chassis for proper airflow and cooling, as the module dissipates 2.5 Watts of power.
- Handle the module using ESD-safe practices to prevent damage to sensitive internal components.
- Route communication cables away from high-voltage power lines to minimize electromagnetic interference (EMI).
