System Installation Requirements for EMC and Lightning Immunity:
1: Ensure the shield of the cable that connects the Flash head to the power supply is
grounded at both ends. Make 360-degree ground connections around the braid or foil
(avoid pigtails).
2: For increased lightning protection adding a lightning rod that extends up 3 feet above
the fixture and 18 inches away from the light is recommended.
3: The drain-wire in the Flash Head cable must be connected to ground at both ends.
Ensure that the wire is short as possible and avoid loops.
4: Ensure the Flash Head is electrically bonded to the tower. Scrape away access paint/
powder coating as necessary.
5: Minimize loop areas by tying all cables against the tower or passing through conduit.
6: Ensure the Power Supply enclosure is electrically bonded to the tower. Scrape away
access paint/ powder coating as necessary.
7: Ground any spare/unused conductors in the Flash Head connection cable at both
ends.
8
: It is recommended that a minimum of ¾” conduit is used for all wiring ways.
9: RS485 connections must be secure and shield or braiding must be grounded
securely.
