The system automatically manages load sharing and failover between the modules.\u003c\/p\u003e\n\u003cp\u003eQ: Is the PW484-51 compatible with both AC and DC input racks?\u003c\/p\u003e\n\u003cp\u003eA: The PW484 model specifically handles 24 V DC inputs. For AC-powered racks, the corresponding PW481 or PW482 variants must be used, ensuring the hardware matches the site power infrastructure.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Seat the module into the compatible base plate (A2BE1D\/A2BE2D).
