Product Instructions for Use

  1. Mounting: Install the VAMP 321 unit into a panel cutout using the provided mounting brackets. Ensure the rear terminals are accessible for wiring and that there is sufficient airflow for cooling.

  2. Sensor Placement: Install optical arc sensors in the various compartments of the switchgear (busbar, cable, and breaker compartments). Avoid placing sensors in direct line with sunlight or heavy external lighting to prevent nuisance tripping.

  3. Wiring: Connect the trip outputs directly to the circuit breaker shunt trip coils. Use shielded cables for communication lines to ensure data integrity in high-noise environments.

  4. Testing: Perform a secondary injection test to verify overcurrent settings and use a flash-test tool to simulate an arc event. Verify that the optical sensors correctly signal the central unit and initiate a trip.
