8. Installation & Wiring
Power Off: Disconnect all system power before installation.
Mounting: Snap module firmly onto Momentum backplane; ground the rack.
Input Wiring (DI1–DI10):
Connect 24 VDC sensor output to DI terminal; common to 24 VDC GND.
Output Wiring (DO1–DO8, NO):
Connect load between DO terminal and AC/DC supply (24–230 V).
Torque: Tighten terminals to 0.5–0.6 N·m.
Verification: Power on; confirm LED status (DI = green, DO = red).
9. Maintenance
Periodic Inspection: Check terminal tightness and LED operation every 6 months.
Cleaning: Use dry cloth only; avoid moisture and chemicals.
Relay Contact Check: Test under load annually; replace if arcing or high resistance.
Environment: Avoid corrosive gases, heavy vibration, and condensation.
10. Safety Notes
Qualified Personnel: Only certified electricians may perform wiring/maintenance.
