Section 4: System Installation Recommendations for EMC and Lightning
Immunity
1: Electrically bond the shield of the Flash Head cable to ground at both ends.
Make 360-degree ground connections around the braid or foil (avoid pigtails).
2: If there is a drain-wire in the cable, connect to ground at both ends
3: Ensure the Flash Head is electrically bonded to the tower
4: Minimize loop areas by tying all cables against the tower or passing through
conduit
5: Ensure the power-supply cabinet is electrically bonded to the tower
6: Ground any spare/unused conductors in the Flash Head cable at both ends
7: Keep wiring tidy with cables performing different functions tied up separately.
Keep power, control and output cables separate. Tie up wires to minimize loop
areas.
For a detailed step by step procedure, refer to “Recommendations for
Proper Grounding to Minimize Lightning Damage” guide available at
