Maintenance■ Inspection

1) In cleaning the fitting, gently wipe with water or mild detergent. Don ’ t use thinner, benzene or alkaline detergent. Suchchemicals might cause discoloration or deterioration in quality and strength, resulting in a damage.
2) Prior to maintenance, be sure to turn off the power.
3) Carry out maintenance properly in accordance with the related law and regulations.
4) If a repair is needed, consult us.

Disassembly and Disposal

Nameplate1) In the period when the product is in use, never disassemble it.
2) For disposal of the product, follow the regulations and rules of your local government.
Reordering
When reordering, please let us know:
・Drawing or drawing No. for the delivered productFig.9
・Manufacturing lot number on the nameplate
If the above information is unavailable, give us any material showing the appearance of the product or details of the product specification(dimensions, mounting interval, lamp type, etc.).
CAUTIONS
1. The product must be installed so that the angle of the lamp house is within a prescribed range from its downward oriented position (0°).
If the angle is out of the range, an insulation failure or electric shock might result.
2. Prior to maintenance or inspection, be sure to turn off the power.
3. Confirm that the screws and bolts are fastened properly and tightly.
4. In the case of the stanchion type, be sure to provide a support at least 800 mm above the bottom of the pole.
5. For outdoor use, waterproof the screwed portion of the conduit, the cable entry fittings and the joint with the stand pole to prevent
rainwater infiltration.
6. When installing the fitting, be sure to connect external wires inside a specified part of the fitting. Don't open any other part of the fitting
unless necessary.
7. When handling the product, be very careful not to scratch the glass globe. Scratching may break the glass globe.
8. The product must be used in a location where it can be used safely according to its explosion protection type (indicated on the body).
9. The supply voltage variation should be within ±6% of the rating.
10. Close unused entries of the terminal box with plugs.
11. The ambient temperature should be within the range of -20°Cto +40°C. The use of the product out of this range may shorten the service
life.
NB: For LZLA1101 and LZLA1501, the allowable ambient temperature range is -20°C to +50°C.
12. In grounding work, be sure to follow the technical standards for electrical equipment and explosion-protected equipment of your country.
Inadequate grounding might cause an explosion, fire or electric shock.
13. Prior to maintenance or inspection, be sure to turn off the power.
14. To prevent shortening of the service life, avoid turning on the fitting in direct sunlight.
15. To avoid noise or malfunctioning, don't use a radio, television or wireless infrared remote control near the fitting.
16. Don’t open the globe. The internal components such as the LED lamp become very hot. Don’t touch the LED lamp since a malfunction or
lighting failure might occur.
17. For white LED lamps, the luminescent color and brightness may vary with individual LEDs because of their nature. Also note that the rateof attenuation with time varies with individual LED lamps.
18. The product must be mounted on a sturdy wall surface or structure which is vibration-free and less susceptible to damage. Otherwise, it
might fall or be damaged.
19. For use in an unfavorable location (a very hot, cold or humid place or a place in which there is strong
wind or vibration, a salt damage environment or a dusty or corrosive gas atmosphere), a special
20. After turning off the power, allow 3 minutes before opening the lamp house. Otherwise, an explosion might occur.
21. The cable gland must be a product specified by SEIWA.
22. Don't clean the flexible fitting with a dry cloth since it may be electrified. Be sure to clean it with a wet cloth. Otherwise, ignition of
flammable gas might occur due to static sparks.
23. For the lamp house replacement type (in which some existing components are used as they are), the external conductor should be heatresistant to 80°C or more.
24. The LED lamp and the power supply unit cannot be replaced.
25. Do ’t look straight at the LED la p. It a da age your eyes.
26. For the lamp house replacement type with G3/4 thread entry, be sure to use the supplied pipe. If the entry is of the G1/2 thread type, besure to use the supplied pipe and the supplied junction box cover. Otherwise, the lamp house might fall or be damaged.
27. The fastening bolts on the control unit chamber housing the control unit have a tensile strength level of A2-50. Don ’ t remove thefastening bolts. Removal of the bolts might cause a fire, electric shock or explosion.

WARNING
Before cleaning, be sure to turn off the power.
Otherwise, a fire or electric shock might result.
If you continue to use the product in an abnormal condition (smoke, odor, etc.), an explosion, a fire or electric shock might
result. If you detect an abnormality, immediately turn off the power switch. Confirm that the abnormal condition has been
eliminated and make a repair call.
Don’t use the product in a strong corrosive gas atmosphere which contains hydrochloric acid or chlorine gases or the like.
Use in a corrosive gas atmosphere might cause the product to corrode and fall, resulting in an injury.
The product should be mounted on a surface robust enough to support its weight, properly according to the instruction
manual. Improper installation might cause the product to fall or result in an electric shock or injury.

CAUTIONAny product not marked as a product for outdoor use should not be used outdoors or in a humid place or near a water
source. Its use in such a place might cause a fire or electric shock.
Do ’t use the produ t at a oltage other tha the rated oltage i di ated o the a eplate.
Otherwise, breakage, fire or electric shock might result.
For a product marked with a frequency, don’t use the product at a frequency other than 50 or 60 Hz (local power supply
frequency). Use at a wrong frequency might cause a fire.
Installation of the product should be carried out by a qualified person.
Installation by an unqualified person is legally prohibited.
Never touch LED light sources and their surroundings.
The light sources and their surroundings are very hot, so an accidental touch might cause a burn.
To ensure brightness and safety, carry out periodical cleaning and inspection.
If you find a problem, discontinue the use of the product and have it repaired by a specialist.
A lighting fitting has a service life. A product which has been used for eight to ten years may have degraded internal partseven if it looks normal. For safety and energy saving, we recommend you check and replace it. The LED module design life is
6,0000 hours (different from the lighting fitting life) when used at an ambient temperature of 30°C, 10 hours per day, 3,000
hours per year. If used at a higher temperature or more hours per year, the life would be shortened. Have a specialist
inspect the product every three years. If used for an extended period without inspection, a smoke, fire, or electric shockmight result.
