LF Series Adjustable Angle Mounting Bracket
Mounting angle can be adjusted from 0° to 90°.
LED illumination units can be installed exibly.
•Mounting angle can be adjusted from 0° to 90° in 10° incre-
ments, providing more options for mounting of the LED illumina-
tion units.
•Illumination angle can be adjusted to suit the operator in various
applications, such as visual inspection.

Safety Precautions
Instructions
•LED modules may vary in illumination colors and illuminance.
•Before designing equipment and powering up illumination units, confirm the
specifications described in the instruction sheet.
•Apply voltage within the rated value, otherwise the LED elements may be
damaged.
•The illumination unit is vulnerable to static electricity. Take sufficient
measure for protection against static electricity and voltage surges.
•Make sure that the illumination unit does not fall during transportation,
installation, and operation, otherwise damage may result.
•Do not pull or push the cable of the illumination unit, otherwise damage
may result. Allow sufficient slack to the cable while wiring.
•Do not apply excessive force. Do not leave a damaged illumination unit
unattended or use a damaged illumination unit.
•Ensure the correct operating temperature. Otherwise internal temperature
rise may result in damage.
•Do not use or store in a place subjected to vibration and shock.
•Do not use in the following places:
* Exposed to direct sunlight, near heaters, high temperatures
* Subject to chemicals, and corrosive gases
(Plastic illumination surface: Iron powder and oil)
* Basements, greenhouses, or other humid places
* Cold storage warehouses (make sure that no freezing occurs)
•Do not loosen screws, otherwise the protection characteristics will be
impaired.
•For the LF2D illumination units, make sure to provide sufficient strength for
mounting panel. Required waterproof characteristics cannot be obtained if
a distorted mounting panel is used.
•To clean the cover, use a soft cloth with water or neutral detergent.
Do not use solvents such as thinners, benzene, or alkaline, otherwise
discoloration, deterioration, or decrease in strength may occur.
•The edge of the cable sheath is not waterproof construction. Water may
invade the LF1B in a capillary action when water splashes directly onto the
cable sheath.
•Do not disassemble, repair, or modify the LED illumination unit. Otherwise
electric shock, fire, or malfunction may occur.
•Turn off power before wiring. Make sure of correct wiring, otherwise electric
shock or damage may result.
•Do not stare directly into the LED illumination unit while it is lit, and do not
project the light to other people, otherwise eyes may be injured.
•LED illumination unit is general-purpose industrial electric device. Do
not use for electronic equipment which may damage the human body or
threaten life in case a malfunction or failure occurs.
•Ensure that the cable does not touch the LED illumination unit.
