8. Installation & Wiring

1. Power Off: Disconnect all system power before installation.

2. Mounting: Snap module firmly onto Momentum backplane; ensure proper grounding.

3. Wiring (Inputs – 120 VAC):

   • Connect 120 VAC line to input terminal; neutral to common (COM) terminal.

4. Wiring (Outputs – TRIAC):

   • Each TRIAC has OUT and COM terminals.

   • Connect load between OUT and COM; route 120 VAC line to COM, neutral to load.

   • For inductive loads: Install external RC snubber to suppress voltage spikes.

5. Torque: Tighten terminals to 0.5–0.6 N·m (14–22 AWG copper wire).

6. Verification: Check connections; power on and confirm LED status (green = active).

9. Maintenance

• Periodic Inspection: Check terminal tightness and LED operation every 6 months.

• Cleaning: Keep surface free of dust and contaminants; use dry cloth only.

• Environment: Avoid corrosive gases, extreme vibration, or moisture.

• Output Check: For high‑cycle applications, verify TRIAC leakage current annually.

10. Safety Notes
