② Loosen the reflector fixing screw, referring to Fig. 7.
③ Lower the lamp house end gently until it is supported by the ｗire.
The lamp house can be opened down to 90 degrees by removing thechain snap from the chain retainer.
④ Loosen the socket cap fixing screws (WAF: 5 mm) and remove thesocket cap.
⑤ Remove the connector from inside the socket (Fig. 8) and pull out
the straight tube LED module (Fig. 9).
⑥ Replace it with a new straight-tube LED module and fit the parts in
the reverse order.

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 1500 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. The supply voltage variation should be within ±6% of the rating.
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. Close unused entries of the terminal box with plugs (metal).
10. 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 servicelife.
11. 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.
12. Prior to maintenance or inspection, be sure to turn off the power.
13. To prevent shortening of the service life, avoid turning on the fitting in direct sunlight.
14. To avoid noise or malfunctioning, don't use a radio, television or wireless infrared remote control near the fitting.
15. 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.
16. Don’t use any straight tube LED module other than the applicable one. Using a non-applicable straight tube LED module might cause afire, electric shock or explosion.
17. After turning off the power, wait four minutes before opening the lamp house. If you open it shortly after turning off the power, an
explosion might occur.
18. The cable gland must be a product specified by SEIWA.
19. 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.
20. 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 countermeasure should be taken.
