2. For products less than 10, 12V DC power supply is sufficient; 10 to 20 products, 36V safe power supply; More than 20 products (it is best not to connect more than 50 products with one power supply) need 220V AC power supply, and the parallel connection mode is more reliable.
3. Wire requirements: 1.5mm copper core cable for wiring within 50m (2.5mm copper core cable for electric ignition products) and 2.5mm copper core cable for wiring around 100m. In addition, if there are many products, the wire diameter should be appropriately increased.
4. Do not use it if it is damaged or the soil falls off during transportation (the vibrating product is noisy or loose). These products are prone to accidents. Please soak the unqualified products in water for 3 to 4 hours before burying them deeply.
5, pay attention to fire prevention: high-quality products are smokeless and slag-free, but some manufacturers use inferior titanium powder in order to reduce costs, and the impurities in it are easy to form high-temperature slag. Falling on the carpet or burning the carpet may also cause a fire. Therefore, a certain amount of water should be poured on the carpet, and asbestos boards can be padded if conditions permit. Therefore, when buying products, we must identify brands and choose manufacturers with stable quality, excellent quality and good reputation.
Stage Waterfalls: If there are many waterfalls and the current required for discharge is large, 220V power supply should be plugged in. When discharging, it is recommended to connect the wire in the middle of the whole waterfall. When discharging water, the waterfall is lit from the middle to both sides to keep the symmetry of the waterfall to the maximum extent. When the waterfall discharges, the power-on time should be appropriately extended to ensure the integrity of the waterfall discharge.
