LF1D/LF2D LED Illumination Units
Safety Precautions
•Illumination units have a product life.
•Because internal elements deteriorate after 8 to 10 years of installation even if they have no defects in appearance, inspection and/or replace-
ment are recommended. Operation condition: temperature 30°C, 3,000-hour operation per year (10 hours per day). (JIS C 8105-1)
•Product life is shortened under high operating temperature or when it is lit for long hours.
•Inspection and/or cleaning by user every 6 months is recommended.
•Inspection by contractors is recommended every 3 years.
•Do not use LF1D/LF2D for a long time without inspection, otherwise smoke, re, or electric shock may occur.l
•Do not disassemble, repair, or modify LF1D/LF2D. Otherwise electric
shock, re, or malfunction may occur.
•Turn off power before wiring. Make sure that the temperature of
LF1D/2D has lowered sufciently before wiring.
•To prevent electric shock or damage, ensure that the wiring is correct.
•Do not stare directly into the LF1D/LF2D while it is lit, and do not
project the light towards other people, otherwise their eyes may be
injured.
•The LF1D/LF2D is a general-purpose industrial electric device.
•Ensure correct operating temperature. Otherwise rise in internal
temperature may result in damage to the unit.
•Do not use in an application which may cause harm or injury to any-
one or threaten life in case a malfunction or failure occurs.
•LF1D/LF2D is for indoor use only. Do not use outdoors, otherwise
insulation failure, electric shock, or failure may result.
Operating Instructions
Warranty
•IDEC warrants LF1D/LF2D to be free from defects in material and
workmanship under normal and proper use for a period one (1) year
from date of shipment. The warranty period is reduced to six (6)
months if LF1D/2D is run continuously over 20 hours. Any defected
product will either be replaced or repaired, not including the expense
required for mounting, replacing, or installation work.
•Warranty does not apply if LF1D/2D is not operated under conditions
described in the instruction sheet or user's manual.
•LED modules and illumination units may vary in illumination colors
and illuminance.
•Before designing equipment and powering up illumination units,
conrm the specications described in the instruction sheet.
•Apply voltage within the rated value, otherwise the LED elements may
be damaged.
•Do not use or store in a location subjected to vibration and shock,
otherwise electric shock or failure will result.
•Do not loosen screws, otherwise the protection characteristics will be
impaired.
•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.
•When using this product in environments subject to dust and water,
make sure that the wiring part of cable or wire are dustproof/water-
proof. Otherwise leakage, electric shock, or failure may be caused.
•Do not use in the following locations:
Subject to corrosive gases, volatile gases, ammable gases, or
chemicals that could affect the safety and reliability of the product.
Subject to electric or magnetic eld
Subject to ammable substances
