5 Control load capacity & turn on/off the switch in reason
5.1 Control the load capacity on each street line
To ensure the LED street light work properly, from low-voltage power distribution cabinet to LED street light power distribution cabinet, if the lead
wire is long ,then there will be huge lead inductance. And this is the same case for turning on/off the LED street light. This will make the sudden
change of the inductance current ,which can threaten the safety of the LED street light. So when installing the LED street light, the quantity for
each street light line needs to be reasonably planed in case of too much load.
Any accessory that may caused the over load or close to full load of the LED street light is prohibited.
5.2 Turn on/off the switch step by step
Sub-switch is needed under the main switch in the distribution system, like the one showed in picture 4. And single main switch to control all
the lines is prohibited. The quantity of the sub-switch depends on the quantity of the branches and the load capacity.
Make sure that all the branches are off before turn on the main switch.
Turn on the branch switch step by step after turning on the main switch, and at the same time, make sure that the interval is more than 5 seconds
between each two switches.
Please never turn off the main switch when all the sub-switches are turned on, because in this case, the impact shock caused by over load and the
leakage inductance from the transformer will lead to huge energy,thus low frequent , high frequent current and voltage surge will damage the
driver, LED or other accessories.

Procedures of turning on the lamp:
Step 1:Turn on S0->S1->S11->S12->S13->S1n, and until all the last stage switches are turned on;
Step 2: Turn on S2->S21->S22->S23->S2n, and until all the last stage switches are turned on;
Step n: Turn on Sn->Sn1->Sn2->Sn3->Snn, and until all the last stage switches are turned on.
Procedures of turning off the lamp:
Step 1: Turn off S0->S1->S11->S12->S13->S1n, and until all the last stage switches are turned off;
Step 2: Turn off S2->S21->S22->S23->S2n, and until all the last stage switches are turned off;
Step n: Turn off Sn->Sn1->Sn2->Sn3->Snn, and until all the last stage switches are turned off.
Transport & Storage requirements
Our LED street light is packaged with hard paper carton box, and severe mechanical shock, exposure to rain,
inversion, rolling and heavy load are all not prohibited. The LED street light should be stored in cool, dry and clean
ambience and the temperature is -20
40
Precautions
Please read the manual carefully before using in case of accidents and damage.
The products don't need to repair in most of the cases, but if maintenance is a needed, please contact us.
Please check the product carefully before using it, and please contact us if there is anomalies.
There will be temperature rise during working, and this is a normal phenomenon.
Security Caution
The warranty does not cover the damage caused by the following reasons:
Input voltage of the LED street light is not the same in the product specifications.
No good ground while the LED street light is working.
External force or throw the lamp into the water or the fire.
Artificial or external irresistible factors (say earthquake,flood, fire,lightning)
Products that is repaired or try to repair by people that is not authorized by our company.
