Safety Notes
- 1. Verify process controller is powered on and idle.
- 2. Test the controller’s operation by clamping to a known grounded piece of metal. Verify the controller’s indicator changes from RED to GREEN. Remove the clamp from the test point.
- 3. Before any other electrical connections are made, secure the A540 clamp to the process connection that is to be loaded.
- 4. Verify the process controller’s indicator changes from RED to GREEN.
- 5. Complete any other process connections.
- 6. Once all other safety measures are active, begin the loading process.
- 7. Once loading is complete, remove all other process connections, then the A540 last.
- 8. Return the A540 clamp to the isolated storage facility, verifying the indicator remains red
