In field retrofits, engineers often observe line-fault alarms during initial power-up if sensor supply voltages drop below the strict 18V DC threshold. Ensuring stable 24V DC bus voltage to field transducers prevents false safety trip commands. Furthermore, because inputs are non-isolated with a shared internal reference, carefully segregating field cabling prevents ground loops across high-noise motor drives.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #1a365d;\"\u003e6.
