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.
