Installation of the Flash Tube Assembly of the Upper Beacon/Strobe Light
WARNING:
ISOLATE THE ELECTRICAL CIRCUITS FROM THE RELATED EQUIPMENT AND THE ENVIRONMENT.
WARNING:
DO NOT TOUCH THE STROBE LIGHTS FOR AT LEAST 5 MINUTES AFTER OPERATION. THE STROBE LIGHT WILL STILL BE HOT.
WARNING:
DO NOT REMOVE THE STROBE LIGHT FOR AT LEAST TEN MINUTES AFTER YOU DE-ENERGIZE THE ELECTRICAL CIRCUITS. THE HIGH VOLTAGE ELECTRICAL CURRENT IN THE CAPACITOR OF THE STROBE LIGHT IS DANGEROUS.
WARNING:
BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
