8. Installation & Wiring

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

2. Mounting: Snap the module firmly onto the Momentum backplane. Ensure proper grounding.

3. Wiring:

   • Connect 100–120 VAC field signals to the corresponding input terminals.

   • Common terminals (COM) are grouped per 8 channels.

   • Use copper conductors (14–22 AWG). Torque terminals to 0.5–0.6 N·m.

4. Verification: Check all connections; power on the system and verify LED status.

9. Maintenance

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

• Cleaning: Keep the module surface free of dust and contaminants.

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

10. Safety Notes

• Isolation: The 1780 VAC isolation does not protect against direct contact with high voltage.

• Wiring: Only qualified personnel should perform wiring. Follow local electrical codes.

• Disposal: Dispose of the module in accordance with local electronic waste regulations.
