Avoid any actions that cause the generation ofelectrostatic charge, such as rubbing with a dry cloth on coating surface of the product.
Don’t cover the product with an inflammable material such as cloth or paper nor put anything in the product. Such amaterial or thing might cause an explosion or fire.

CAUTION
Don’t use the product at a voltage other than the voltage indicated on the nameplate. The voltage variation
should be within ±6% of the rating. Otherwise a damage, fire or electric shock might result.
Don’t use the product at a frequency other than the local power supply frequency (50 or 60 Hz).
A wrong frequency might cause a fire.
The product should be installed by a qualified person.
Installation by an unqualified person is legally prohibited.
Never touch the lamp and its surroundings while it is on or just after it is turned off.
The lamp and its surroundings are very hot. An accidental touch might burn yourself.
Because this product is painted non-metallic coating , please refer to the note below.
・Avoid friction ・No dry cleaning ・Do not mount in areas with flowing, non-conductive products

CAUTIONS①②③④

Prior to installation, be sure to turn off the power.
Confirm that the screws and bolts are fastened properly and tightly.
When installing the fitting, be sure to connect external wires inside a specified part of the fitting. Don’t open any other part.
The ambient temperature should be within the range of -25 ºC to +55ºC.
T6 (Gas), T85ºC (Dust) : -25ºC ≤ Ta ≤ +45ºC
T5 (Gas), T100ºC (Dust) : -25ºC ≤ Ta ≤ +55ºC⑤ The supply voltage variation should be within ±6% of the rating.
⑥ The lighting fitting must be used in a location where it can be used safely according to its flameproof protection type (indicatedon the body).
⑦ Be sure to use certified Ex components to plug the entries of the terminal box which are not used.
⑧ For the cable gland, be sure to use a certified Ex component.
⑨ Be sure to use Ex component certified products and cables which are suitable for the operating temperature range, referringto the following.
-25ºC ≤ Ta ≤ +45ºC
Plug: -25 ºC to +75ºC Cable gland: -25 ºC to +75ºC Cables: -25 ºC to +75ºC-25ºC ≤ Ta ≤ +55ºC
Plug: -25 ºC to +85ºC Cable gland: -25 ºC to +85ºC Cables: -25 ºC to +85ºC⑩ The accessory plug can be used up to ambient temperature +50 ℃.
⑪ Confirm that the fitting is adequately grounded.
⑫ Prior to maintenance or inspection, be sure to turn off the power.
⑬ Don’t use the product in a corrosive gas atmosphere which contains hydrochloric acid, high-concentration chlorine gas or thelike.
⑭ To prevent shortening of the service life, avoid turning on the fitting in direct sunlight.
