Hazardous Wiring Separation: Maintain strict physical segregation between hazardous area field wiring and safe-area output cabling. Shield Grounding: Connect field cable shields to the main cabinet functional earth busbar at a single earthing point to prevent loop currents. Thermal Ventilation: Ensure at least 10 mm of clear airspace above and below the module housing to enable passive convection cooling within the cabinet.\u003c\/p\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: Can the 51191699-100 module be installed or replaced on an energized backplane?\u003c\/p\u003e\n\u003cp\u003eA: Yes.
