Ensure shield ground drain wires from field loops do not return through the module's 24 VDC input terminal block.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003ePower Off Verification: Confirm input 24 VDC power feed lines are de-energized prior to wiring or terminal connection unless operating within a validated hot-swap procedure under redundant configuration.\u003c\/li\u003e\n\u003cli\u003eSlot Placement: Insert the module firmly into slot P1 or P2 along the chassis guide rails until the rear backplane connectors seat completely. Tighten upper and lower retaining screws to 0.5 N m torque.\u003c\/li\u003e\n\u003cli\u003eRedundancy Matching: Verify both power supply slots contain identical PW484-10 S1 units with matching style codes to ensure balanced load sharing.\u003c\/li\u003e\n\u003cli\u003eTerminal Wiring \u0026amp; Grounding: Connect 24 VDC power conductors to designated screw terminals.
