Compatibility\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eThis module with Internal Terminations (01) is not physically compatible with racks configured for External Termination blocks unless the corresponding rear I\/O module is replaced. If converting from an older 3500\/45 system with option 02 (External Terminations), ensure that the internal field wiring layouts are updated to match the direct terminal connections. Note that firmware version parity with your 3500 Rack Configuration Software is required; older configuration software versions may not support the CN-specific regional configuration parameters.\u003c\/p\u003e\n\n\u003ch3\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eWhen deploying DC LVDTs, ensure that the DC excitation voltage matches the transducer specification. Unstable DC power sources in adjacent cabinet spaces can inject electrical noise, leading to false position-trip alarms. For differential expansion setups, double-check configuration parameters: choosing the wrong sensor curve can lead to severe offset errors on steam turbine warm-up cycles.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eSince the internal terminations option brings physical wiring directly to the rear of the rack, ensure proper cable strain relief is installed. Standard twisted, shielded pair cabling must be utilized for all position sensor runs. To prevent electrical ground loops that corrupt signal readings, ensure sensor shields are terminated strictly at the 3500 rack system ground, keeping the sensor-end shield completely insulated.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 15px; margin-bottom: 1.5rem;\"\u003e\n  \u003cstrong style=\"color: #9b2c2c; display: block; margin-bottom: 5px;\"\u003eCRITICAL WARNING\u003c\/strong\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0;\"\u003eDisconnect all power sources supplying the 3500 rack before installing or removing the monitor module and its corresponding rear I\/O card.
