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 – 120 VAC):

   • Connect load between output terminal and neutral; 120 VAC line to common (COM).

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

5. Modbus Wiring:

   • Connect RS‑485 (+/−) to Modbus network; use 120 Ω termination resistor at bus ends.

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

7. Verification: Check connections; power on and confirm LED status and Modbus communication.

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.

• Modbus Network: Check termination and cable integrity annually.

10. Safety Notes

• 120 VAC Hazard: Only qualified electricians should perform wiring; follow local electrical codes.

• Voltage Limits: Do not exceed 132 VAC on inputs/outputs.

• Isolation: Maintain 500 VAC isolation between field and bus circuits.

• Inductive Loads: Always use external suppression (RC snubbers) to protect outputs.

• Disposal: Dispose of module per local electronic waste regulations.
