High voltages are present inside the light assembly. Wait at least 5 minutes
after disconnecting the power before servicing this unit.
Listed below are some important safety instructions and precautions you should
follow:
• Read and understand all instructions before operating this system.
• Any maintenance to the light system must be done with power turned off.
• Any maintenance to the light system must be performed by a trained electri-
cian who is thoroughly familiar with all applicable national and local codes in
the country of use.
• Never alter the unit in any manner. Safety of the unit may be affected if ad-
ditional openings or other alterations are made to the internal components or
housing.
• The nameplate should NOT be obscured, as it contains cautionary and/or
other information of importance to maintenance personnel. Ensure the name-
plate remains readable if the housing exterior is painted.
• If the dome is damaged in any way, it MUST be replaced.

while disassembling or reassembling the unit. Lubricated threaded joints
exposed for long periods of time may attract small particles of dirt or other
foreign materials. Housing and cover joints should be reassembled immedi-
ately, with all the threads fully engaged.
