Preparation of solar street lights installation
1. Selection of disassembly and assembly locations for solar powered street lights: The disassembly and assembly locations should be near the installation site to facilitate transportation after assembly. In addition, the installation point should be covered with rainproof cloth to prevent abrasion, scratches, and stains caused by protruding ground or fine sand and stains.

2. Installation personnel and tools of solar powered steet lights: 3-6 professional installation personnel (the installation task can be increased appropriately), each person is equipped with a set of installation tools, including a multimeter, a large opening (guard mounting anchor nut) and a small opening ( Install other nuts), a flat screwdriver, a triangle lock tool, a Phillips screwdriver, and a sharp pliers, and several rolls of insulating tape and waterproof tape. It is better to prepare a crane and a lift truck if conditions permit.

3. Count the solar street lamps according to the delivery list: disassemble and check the parts one by one with reference to the packing list and check for damage such as bumps, wear, deformation, and scratches. Unqualified products are prohibited from installation.

4. Light pole components and easy-to-wear accessories (components, lamp caps) must be placed with soft cushions to avoid unnecessary damage such as scratches during the installation process.

5. When the lower pole assembly is placed, there must be an iron trap at its upper end to facilitate the installation of the upper pole assembly.

Solar Street lights Assembly
1. Assemble the light pole components: the upper and lower light pole components, the light arm components, and the fixing structure of the solar battery components.

A. Install the solar lamp arm: Tie the exposed sheath wire end of the lower lamp pole with a thin iron wire and wrap it with black tape; the other end of the thin iron wire passes through the lamp arm assembly; pull it slowly at the top of the lamp arm assembly The thin iron wire allows the thin iron ribbon moving sheath wire to pass through the lamp arm assembly while the lamp arm assembly gradually approaches the lower lamp pole until the panel on the lamp arm is aligned with and close to the lamp arm boss on the lower lamp pole, and then a suitable The bolts fasten the lamp arm assembly to the lower lamp pole; when fixing the lamp arm assembly, avoid squeezing the sheath wire, causing the sheath wire skin to be damaged or even cut; disconnect the connection of the thin iron wire to the sheath.

B. Install the lamp (with a light source inside): Approach the upper end of the lamp arm when the lamp is turned on, and pass the exposed sheath wire into the lamp from the end of the lamp; pull the sheath wire and insert the lamp into the lamp arm at the same time, the two overlap The length is 150mm; connect the sheath wire to the wiring terminal inside the lamp, and pay attention to the correct positive and negative wiring when wiring. Turn the lamp with the lamp arm as neutral, so that the lampshade is facing the ground, then fix the lamp on the arm; turn off the lamp.

C. Light pole assembly on the assembly:
1). Fasten the bracket assembly and the corner post to the upper pole assembly in turn, and the threaded connection part should be evenly stressed and fastened; while connecting the bracket and the angle steel frame, use a thin iron wire to pull the sheath line from the lamp pole The middle is led into the angle steel frame through the bracket assembly.

2) Place the module guard plate in the angle steel frame, and then place the module on the guard plate; when placing the module, the junction box is at a high place. When the module is placed horizontally, the junction box should be close to the light pole assembly.

3) Connect the components according to the system voltage and component voltage of the solar street lamp. For example, the system voltage of the solar street lamp is 24V and the component voltage is 17Vak18V. The components should be connected in series. The series connection is the positive (or negative) of the first component. Connect to the negative (or positive) of the second component. If the component voltage is 34V, the components should be connected in parallel. The parallel method is to connect the positive and negative poles of the first component to the positive and negative poles of the second component. Use a small flat-blade screwdriver to crimp the terminal block of the junction box. The red wire is required to connect the positive pole and the blue wire to the negative pole. After the wiring is completed, tighten the anti-nut on the outlet end of the junction box and apply 7091 to the terminal of the junction box. Seal the silica gel, apply the amount of glue so that the wire entry point in the junction box is completely sealed, and then buckle the junction box cover. The junction box cover should be fastened and not snapped back.

4) Use a multimeter to check whether the component connection (connected to the controller end) is short, and at the same time check whether the component output voltage meets the system requirements. In fine weather, its opening distance voltage should be greater than 18V (system voltage is 12V) or 34V (system voltage is 24V). After installing and testing the components, the power cord is connected to the positive pole of the controller terminal. Use insulating tape to wrap the exposed core of the core. The insulating tape wraps two layers; Note: The components should be handled with care during the installation process to avoid damage to tools and other appliances.

5) The components and component brackets are fastened with M6*20 bolts, N6 spirals, and washers 6. When installing, the bolts should be installed from the outside to the inside, and then put on washers and tighten with nuts. When tightening, the bolt connections must be firmly connected without looseness.

6) Connection of upper and lower light pole components: Take out the sheath wire in the lower port of the upper light pole assembly and smooth it; loosen and smooth the thin iron wire wrapped around the lower light pole. The sheath wire from the lower port of the upper and lower light pole assembly is fixed on the thin iron wire of the upper port of the lower light pole. Slowly pull the thin iron wire under the lower light pole assembly, and at the same time lift the upper light pole assembly to a suitable position. When the lower end of the upper light pole assembly runs down to about 100mm from the upper end of the light pole assembly (the sheath wire passing through the lower light pole assembly should be under light stress at this time), the sheath wire of the upper port should be tightened with nylon and then Use nylon cable ties to fix the tightly bound sheath wire on the hook of the upper port of the lower light pole assembly, and then insert the upper light pole assembly into the lower light pole assembly to a suitable position, and evenly tighten the bolts of the lower light pole assembly until it reaches Claim. Disconnect the thin iron wire from the sheath wire. After the components are completed, ensure that the component fixing frame faces the south of the installation site.

Vertical lights
1. Put the lifting rope in the suitable position of the light pole
2. Slowly hoist the lamp, and pay attention to avoid scratching the components by the crane wire rope.
3. During the hoisting process, when the lamps are completely off the ground or completely separated from the load, at least two installers use a large plate to clamp the flange to prevent the upper end of the lamp and the crane due to the bottom swing during the starting point. The sling rubs and damages the sprayed layer or even more.
4. When the lamp is hoisted directly above the foundation, the group slowly lowers the lamp, while rotating the lamp pole, adjust the lamp head to face the street, and the long hole on the flange is aligned with the anchor bolt.
5. After the flange falls on the foundation, put on the flat washer 30 (or flat washer 24), the nut of the spring washer 30 (spring washer 24), and the horizontal ruler to adjust the verticality of the light pole. If the light pole is not on the ground Place a gasket under the flange of the lamp pole to make it vertical to the ground. Finally, use a wrench to tighten the nuts evenly. Apply thread-locking glue before tightening. For M24 bolts (grade 8.8), the rotating torque is 650.6 NM, and for m30 bolts (grade 8.8), the rotating torque is 1292.5 MN.
6. Remove the lifting rope.
7. Check whether the component faces the south, otherwise adjust it. Adjust the direction of the components: use the necessary devices to send 1-2 installers to the appropriate height. The installers use a wrench to loosen and tighten the bolts of the upper light pole assembly one by one, and then twist the upper light pole assembly to the appropriate position based on the compass. , And finally, tighten the bolts of the lamp pole assembly one by one, and ensure that the bolts are evenly received.

4. Clean up the site to ensure a clean and tidy environment; check the inventory tools to make sure that there are no omissions.

Matters needing attention during the solar powered street light installation
1. Handle with care when installing components, and it is strictly forbidden to short-circuit or throw components.
2. The power cord is sealed with silica gel at the junction box, the light pole, and the component line. The component connection line must be firmly fixed at the bracket to prevent the power cord from being loose or even falling off due to long-term sagging or dragging.
3. When installing the lamp holder and light source, handle it gently to ensure that the lens is clean and free of scratches. Rolling and throwing are strictly prohibited.
4. Do not move the battery and control valve when moving the battery, and it is strictly forbidden to roll or throw the battery for a short distance.
5. Pay attention to the positive and negative poles when wiring, and it is strictly forbidden to connect reversely. The crimping of the wiring terminals is firm and not loose. At the same time, attention should be paid to the connection sequence and it is strictly forbidden to short-circuit the line.
6. Do not touch the components and the positive and negative poles of the battery at the same time to prevent the risk of electric shock.
7. Avoid scratching the lamp body during installation.
8. The bolts of the lamp cap, lamp arm, upper lamp pole assembly, and solar battery assembly lamp are firmly connected without looseness.
9. A protective plate must be added when installing components.
10. The galvanized hole of the lamp pole is sealed with a special degree of silica gel, pay attention to the appearance.

Installation Environment of the solar street lights
1. There should be no obstructions around the installation site to ensure that the components can be lighted normally.
2. The installation site must have smooth drainage.
3. If there are low-lying water points such as rivers and puddles 10 from the installation site, the lowest point of the foundation must be higher than the highest water level within 50 years of the water point.
4. No electric cables, optical cables and other public facilities can be laid underground at the installation site, which will affect the construction and installation.
5, 8-9 meters foundation
The quality of the solar street light pole is affected by the length, width and height of the flange, whether the welding is single-sided or double-sided, the diameter, the wall thickness of the light pole, the main surface treatment method (painting, spraying, fluorocarbon paint, whether the whole is hot Galvanizing, etc.), the choice of steel, and the quality of surface polishing are closely related.
Generally speaking, we recommend that customers use 釸 poles instead of large and small poles, nor even straight poles for solar engineering street lights.
