When performing hot-swaps or hardware updates, ensure that the station address switches on the unit are matched identically to the replaced hardware. The newer AC500 platform serves as the migration path, but direct component substitution is not supported without software refactoring and bus-coupler modifications.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #1a365d; margin-top: 1rem;\"\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eVoltage fluctuations on the 24 V DC distribution line feeding the GJR5250900R0202 can induce unexpected bus communication drops.
