Power Terminations for SAGE RTU 2400
Issue:
How to correctly connect input power to the SAGE RTU 2400 baseboard during installation.
Product:
SAGE RTU 2400
Environment:
- SAGE RTU 2400 Baseboard
- NEMA 4 or NEMA 12 enclosures
- DC power supply (10–33 VDC) or optional AC/DC converters
Cause:
Improper wiring or misunderstanding of terminal assignments can lead to power supply issues, RTU malfunction, or damage to components.
Resolution:
- The SAGE 2400 baseboard requires +10 to +33 VDC input power.
- Connect power to Terminal Block TB1:
- Pin 3: Positive (+10 to +33 VDC)
- Pin 1: Ground (Return)
- Pins 2 and 4 are provided for looping power to another module if needed.
- If using AC or other DC sources (e.g., 48 VDC or 129 VDC), the enclosure will include a +24 VDC power supply and separate terminations for field power.
- Ensure input power is de-energized before wiring and verify proper grounding using the external grounding stud connected to the RTU grounding system.
