Installation Tips
1.The product is installed vertically at the pressure interface on site.
2.When installing in the open air, the transmitter should be placed in a ventilated and dry place as far as possible to avoid direct exposure to strong light and rain, otherwise it will make the performance worse or a fault occurs.
3.When the product is installed in the lightning area, the "lightning protection" should be marked when ordering. At the same time, it is recommended that users install lightning protection devices on site, and ensure reliable grounding of products and power supply, which can reduce the probability of lightning damage to transmitter.
4.if the transmitter has no output or abnormal output after installation, please check:
(1) Whether the electrical connection is accurate and firm;
(2) Check whether the supply voltage is too low and whether the load resistance is too large.
