Notes of the Installation & using
LED is widely used outdoor with poor working conditions, which keeps the strict requirements for its reliability. According to the failure analysis,
except for the factors from the lamp, good electricity ambient and correct installation have a great effect on the stability of the drive. Below are
the precautions for the installation and using:
1 Installation Instructions
1.1 There are 3 lines for AC input, which are L,N,G and please wire and power the lamp according to the product specifications.
1.2 Voltage fluctuations from the state grid should be within the voltage range of the lamp. There will be highlights on the Item NO.2 in “Power Systems”
below.
1.3 Please make sure that the lamp has a good connection with the ground line while installation.
1.4 Surge protective device is provided when buying the products from us, but lightning protection device is also needed while installation in case of the
damage caused by lightning.
1.5 The power cord of the LED street light is must be the special line, with no other mixed cords, especially the cords of the HPS or other high voltage
shock lamps.
1.6 Please don't expose the driver out of the lamp to reduce the damage caused by poor condition bad environment.

2 Power Systems
There are 3 lines for led street light, namely L line, N line, and GND. The power system of the LED lamps can be single-phase & three-phase power
supply. Wiring is showed as the one in picture 1 and single-phase two-wire system is prohibited. When using three-phase power supply, TN-S system
is required, namely three-phase five-wire system. The wiring is showed below in picture 2 and three-phase four-wire system is prohibited. These two
power system needs to ensure that the GND is connected with the ground of the main power supply system.
Three-phase five-wire system is widely applied in most of the cases, and the electrician needs to take care of the three-phase load balancing. And if there
is no balance for the three-phase load,1) there will be huge surge current at the input terminal of the load when turn on/off the switch,(And this high
current is caused by high voltage in a short time at the grid, like a wave. When large-capacity electrical equipment turns on/off, there will be surge voltage
caused by the inductance in the grid, which will cause the surge current to damage the LED driver of theLEDs ). The phase that is caused by low voltage
may prevent the control circuit of the led lamp from being normal working state, thus affect the energy saving or the light-efficiency of the LED.
Picture 1 Wire of Single-phase three-wire system
(notice the balance of the three phases)
Picture 2 Wire of three-phase five-wire system (notice the balance of the three phases)
3 (Power lines)
LED Street Light uses three-phase output current and stable voltage, therefore the following points needs to be taken care in case that the driver & LED
is damaged by them.
ƹMake sure that the AC line from the low-voltage distribution is provided by the specific transformer, the input AC voltage is not exceeding the working
voltage range of the LED lamp. Public transformer is prohibited because of the low power quality and huge voltage fluctuation. Current harmonics,
caused by the current variation and the driver resistance, will change into voltage harmonics and come to the power distribution cabinet. This sometimes
leads to the unbalanced current, overload and poor electromegnatic power ambience
ƹPower lines shared with HPS, metal halide and other high-intensity discharge lamps is not allowed because of the unstable arc discharge in the tube
at the initial phase, which can leads to surge voltage as high as 2-6KV.

ƹSpecific power line can not power the large electrical equipment or factories temporarily or for a long time. Like: electric welder, mixer, impact drill,
packing machine, large-scale heavy equipment, cement factory,steel plant .etc. Because these machines and working conditions makes the instability
of the state grid.
4 Requirements of the installation for the driver
4.1 Reliable grounding
- The Led lamp and the pole needs to be reliable grounded in case of thunder shock. In order to make sure
the safety of the electricity, connecting the ground line with the N-line is not allowed, and unconnected
ground line of the LED lamp is also prohibited.
4.2 Connection of the power cord
- When connect the LED lamp and the AC input, please make sure that the cord needs to be inserted into
the pole and then connect the AC input of the driver. Let the connector upward and then wrap with insulation tape or waterproof junction box to
prevent the connecting part from the moisture or the rain.
Otherwise, there will be security risks on the one hand, and on the other hand, huge voltage fluctuation will ruin the LED and the driver. Please
refer to the connection line of the picture 3 below.
4.3 Diameter requirements of the N-line
- In many cord(three-phase power supply),the diameter of the N line is small, which has a great impact on 3 pieces led street light with
single-phase power supply. Because the led street light is powered by three-phase five-wire system, which requires the same diameter
of A,B,C three phase line to adapt to the Schematic diagram of use waterproof junction box

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.
