the fixture to rain or moisture.
Do not look directly at the LASER light beam while the fixture is on.
Do not touch any wire during operation .
The unit should be mounted via its screw holes on the bracket. Always
ensure that the unit is firmly fixed to avoid vibration and slipping while
operating. Always ensure that the structure to which you are attaching
the unit is secure and is able to support a weight of 10 times of the
unit’s weight. Also always use a safety cable that can hold 12 times of
the weight of the unit when installing the fixture.
The equipment must be fixed by professionals. And it must be fixed at
a place where is out of the touch of people and has no one pass by or
under it.
Operating Premises: Whenever possible, the operation of a LASER
should be done in a room or in an enclosed or delimited place for this
purpose.
The access of room and openings to the outside must not be located
in the axis of a direct beam.
The floor must be free of obstacles. The causes of accidental reflection
and scattering of laser beams must be removed (misplaced windows,
furniture or objects with polished faces).
The paintings (walls, partitions, ceilings ...) and flooring should
preferably be matt. The diffuse reflections of class 4 lasers, focused
beams of lasers of class 3 to visible or near infrared light should be
considered dangerous and treated as such.
When using powerful lasers (Classes 3 to focused beam or 4),
eliminate the beam potential impact on flammable materials (wood,
paper, fabric or plastic) that can be in from fire in power densities of
the order of several W.cm-2 applied for a few seconds.
The access to the laser emission zones should be reported using the
signs in accordance with the Ministerial Decree of 4 November 1993
"Signs of safety and health in the workplace" and the NF X 08-003
"Symbols graphics and symbols - colors and safety signs "of December
1994. This signaling is completed by the words of the class of laser
product and the instructions provided in the NF EN 60825-1 standard.
Such access can be controlled, at least when lasers are operating.
