The 3500\/61-01-00 mounts in a Bently Nevada 3500 rack, occupying one full-height front slot. The corresponding I\/O module (option 01) occupies one full-height rear slot. Connect RTD or TC sensors to the I\/O module terminals per the wiring diagram. For 3-wire RTDs, ensure the two current sources are properly connected; for 4-wire, use the single supply. Configure the monitor using the 3500 Configuration Software: set full-scale ranges, alarm setpoints, and delays. No manual calibration is required. Always follow standard industrial safety practices and ensure the system is de-energized during installation.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eThe 3500\/61-01-00 is designed for long-term reliability.
