Installation and Maintenance Instructions
EXPLOSION HAZARD—To prevent ignition of hazardous atmo-
spheres, disconnect the fixture from the supply circuit before
opening it.
SHOCK HAZARD—Strobe systems generate high voltages. Dis-
connect power from the strobe system and wait at least 5 minutes
before opening the unit. Do not apply power to the unit while the
unit is open. Failure to follow this warning could result in serious
injury or death.
To replace the strobe tube:
1. Disconnect power to the light.
EXPLOSION HAZARD—The effectiveness of the explosion-proof
enclosure must be maintained. Do not damage the dome or
threads while disassembling or reassembling unit. Lubricated
joints exposed for long periods of time may attract small particles
of dirt or other foreign materials. Body and cover joints should be
reassembled immediately with all the threads fully engaged.
2.
Remove the glass dome assembly from the main housing by
rotating the dome assembly counterclockwise.
3.
Loosen the lens-clip screw 1 to 3 turns and rotate the clip
90 degrees.
4. Remove the lens to expose the lamp.
HANDLE STROBE TUBES CAREFULLY—Strobe tubes get hot
enough to burn you. Always allow these tubes to cool before
handling them. Strobe tubes are also pressurized and, if broken,
can result in flying glass. Always wear gloves and eye protection
when handling strobe tubes. Failure to follow this warning may
result in personal injury.
