rating supported by the AMN31 S1 nest assembly?\u003c\/p\u003e\n\u003cp\u003eA: The internal 24 VDC power distribution plane is rated to supply and dissipate up to 100 W total across all populated module slots.\u003c\/p\u003e\n\u003cp\u003eQ: Can modules be inserted or removed from any of the 31 slots while the power bus is energized?\u003c\/p\u003e\n\u003cp\u003eA: Yes, online hot-swapping of individual terminal I\/O cards is supported, provided proper ESD grounding guidelines are strictly followed during module insertion and removal.\u003c\/p\u003e\n\u003cp\u003eQ: What environmental protection rating does the AMN31 S1 nest frame hold?\u003c\/p\u003e\n\u003cp\u003eA: The unit meets NEMA 4X and IEC IP66 standards for dust-tight and water-resistant physical enclosure
