Notes of installation and using

1 Three principles of installation and using:

   (1) The electricity net voltage should be in the marked range of working voltage,for example , the input  voltage of supply power is 170~250V, it should not be connected with the electricity net voltage of 280V.

   (2) Don’t use with abnormal load :don’t over loading, ultra light load, the supply power and the load should  be matched.  

   (3) There can not be use for two or more power supply output by parallel connection, otherewise, that can be  from high voltage return to low voltage that can be caused the power supply damaged.

    A  Stabile voltage(see the load features of product 1)

    B  Stabile current(see the load features of product 2)

  (4) To make a installation and environment of good for heat exchange;

    A  It is strictly prohibited installing in the environment of high temperature

    B  To make the heat exchange by three kinds of ways of heat transferring

       a. Bare in the floating air

       b. The space of heat exchange is as large as possible

       c. Installed on the metal board of large area ,and contacted well,give out the heat by the metal board

2  Steps of installation:

    (1)For good of heat exchange , fix the supply power on the large metal board directly;

    (2)The connection should be fastness,the input and output line should not be connected in reverse;the output  “+”connected with the LED“anode”,the output“—”connected with the LED“cathode”;

    (3)Make sure the voltage between the connection and supply power is the matchable by multimeter,shut the  brake when affirm.

Remark: there are three kinds of wirings on the LED switching supply power of our company: blue and brown,   black and red, black and white,the wirings of brown, red , white are the output anode of supply power,the wirings  of blue, black , black are the output cathode of supply power;the input wiring is white.The wiring of waterproof  with black wiring-protector outside is the input wiring,The wiring with white wiring-protector outside is the output  wiring,the output wiring core of white is “anode”, and the black is“cathode”.

The using environment of product and deposited condition

1  Product outdoors can be used :temperature -25~+40;relative humidity 100%

2  Product indoors can be used:temperature -10 ~+40;relative humidity ≤ 90%

3  Depostied in:temperature -10~+60;relative humidity ≤85%

Note: Please operate strictly according to the Product Operating Instructions. Do not directly use the products in harsh  environments (such as:PH larger areas or in water use)

Warranty and Our service 

1  The product is warranted for two years when used in gear,from the date of leaving factory.

2  The warranty is invalid when one of the cases below happens :

(1)The product went wrong because of not used by the instructions;

(2)The product went wrong because of the user removed the parts inside by himself/herself;

(3)The form of product shattered serious, or transformative;

(4)The date of leaving factory or the gliding number on the product has be scraped off or be altered;

If product quality problems occur within the warranty period, free replacement of the same type of product or repaired bad product.
