PRECAUTIONS FOR CORRECT USE
1. MLC is based on ML. Please note the following.
ML covers and filters can be installed for MLC, but they cannot be ordered in assembled unit and must be purchased separately.
AC/DC 100V unit for ML cannot be used for MLC.
MLC can only be ordered in assembled unit. The light cartridge and housing cannot be ordered separately.
2. When using the product outdoors, please use it within the IP65 standard and the specifications specified by us.
Installed the panel without any bumps, debris, or burrs on the panel surface, and with no kinks or bends in the packing.
The tightening torque of the mounting nut when attaching to the panel should be 0.98 to 1.47 N･m or less for Oil and water-tight typeand 1.47 N･m or less for No protection type.
3. Brightness is expressed in terms of iluminance, but TYP.7000cd/㎡(reference value) is measured at the highest luminance on the area of
about 4 squares of diamond-cut cover surface.
The brightness of lighting type is measured in a dark room at a distance of 50 cm directly below. Approx. 70 lux (reference illuminance)※ For handling instructions and precautions other than the above, please refer to “Safety Precautions for All Indicators”.

Safety Precautions for All Indicators
1. Notes on contents of Catalogs(1) Rated values, performance values, and specification values of Sumulon products listed in this catalog are values acquired under respective conditionsin independent testing, and do not guarantee values gained in combined conditions.
(2) The ambient operating temperature(humidity) is guaranteed by evaluation based on characteristics, and does not guarantee continuous use for a long
period of time near the upper or lower limit of the ambient operating temperature(humidity) or permanent use at that temperature(humidity).
(3) Reference data and reference values listed in catalogs are for reference purposes only, and do not guarantee that the product will always operate
appropriately in that range.
(4) The specifications / appearance and accessories of Sunmulon products listed in catalogs are subject to change or termination of sales without notice,for improvemnet or other reasons.
(5) The content of catalogs is subject to change without notice.

2. Note on applications(1) If using Sunmulon products in combination with other products, confirm the following suitability by yourself. Sunmulon shall provide no guarantees
regarding the combination suitability.
(a) Regulations, satndards, or laws to which your machinery, equipment, ect. must conform(b) Functionality and safety of your machinery and equipment(2) Wiring and installation that ensures the Sunmulon product used in your system, machine, device, or the like can perform and function according to
its specifications.
(3) When using Sunmulon products, be cautious when implementing the following.
(a) Use of Sunmulon products with sufficient allowance for rating and performance.
(b) Safety design, including redundant design and malfunction prevention design that prevents other danger and damage even in the event that
Sumulon product fails.
(4) Sunmulon products are designed and manufactured as general-purpose products for general industrial products. They are not intended for use
in the following applications, and in the event that you use Sunmulon product for these applications, unless otherwise agreed upon between you
and Sunmulon, Sunmulon shall provide no guarantees whatsoever regarding Sunmulon products.
(a) Safety devices intended for human body protection(b) Direct control of transport equipmnt (railroads / airplanes / ships / vehicles / vehicle instruments, etc.)(c) Space equipment, submarine equipment(d) Nuclear power control equipment, radiation related equipment(e) Combustion equipment, electric heat equipment(f) Disaster prevention and security equipment(g) Elevating equipment(h) Amusement facilities(i) Facilities subject to government or industry regulations(j) Use in applications that require a high degree of safety, any other equipment, instruments, or the like that could endanger life or human health

3. Warranty(1) The warranty period for Sunmulon products shall be 1 year after purchase or delivery to the specified location.
(2) Warranty scope should a failure occur in Sunmulon product during the above warranty period for reasons attributable to Sunmulon, then Sunmulon shallprovide that product, free of charge, the same quantity. Further, in no event shall liability of Sunmulon exceed the individual price of the product onwhich liability is asserted.
(3) Failures cause by the following reasons shall be deemed outside the scope of this warranty.
(a) The product was handled or used deviating from conditions / environment listed in the catalogs(b) The failure was caused by reasons other than Sunmulon product(c) Modification or repair was performed by a party other than Sunmulon(d) Replacement of maintenance parts, installation of accessories, or the like was not performed properly in accordance with the user’s manual andcatalogs(e) The failure could not have been predicted with the scientific and technical standards at the time when the product was shipped from Sunmulon(f) The failure was due to other causes not attributable to Sunmulon (including cases of force majeure such as natural disasters and other disasters)(4) The warranty listed in this Safety Precautions is the full and complete warranty for Sunmulon products, and Sunmulon shall bear no liability whatsoever
regarding special damages, indirect damages, incidental damages, or passive damages that occurred due to Sunmulon product.

4. Handling precautions for indicator(1) Wire the terminals with correct polarity. Connecting connectors backwards may cause a power short, resulting in burnout.
(2) Turn off the power to the product before starting installation, removal, wiring, maintenance, or inspection. Failure to turn power off may cause
electrical shock or fire.
(3) Be careful of electrostatic breakdown when handling.
(4) Do not drop or otherwise apply strong force to the indicator.
(5) Do not place heavy objects on the indicator.
(6) Do not operate or use the housing by itself. Use the indicator with assembled the cover.
(7) When removing the cover and filter, using a sharp object (screwdrivers, tweezers, etc.), hard object (metal, etc.), or with a large or sudden force,
may cause deform or damage the indicator.
(8) Do not use the indicator under loads that exceed the rated capacity or other ratings. Doing so may result in burnout accidents.

Sunmulon Co., Ltd.

PRECAUTION-1

Safety Precautions for All Indicators(9) Assemble correctly according to the handing instructions. Do not assemble or disassemble the product other than as described in the catalog,
as this may cause defects or accidents.
(10) Illumination(a) Do not apply a voltage between the LED terminal that is greater than the rated voltage. Doing so may damage the LED, cause lighting failure.
(b) LEDs cannot be lit directly by AC circuit should be provided rectifier smoothing circuit for products other than AC input type.

(c) When wiring, pay attention to the polarity of the terminals.
(d) Simultaneous lighting may not be possible with Dual-Color, 3-Color illumination or Split-Face illumination, check the catalog.
(e) Apply voltage directly to LEDs of Non-built-in resistor type will damage the LEDs, so connect an appropriate external resistor.

(11) Wiring(a) When tightening terminals or connecting connectors, do not apply more force than necessary from the back side.
Support the indicator with one hand as it may slip out of the front of the panel.
(b) Use the applicable connectors listed in the catalog for each model.
(c) Do not apply a soldering iron to the indicator housing. Doing so may deform the terminals and cause defects.
(d) Hand solder with the terminals facing down to prevent flux from penetrating into the indicator.
