Installation Precautions:
- In order to reliably prevent lightning attack, you can respective by concatenation SPD at the antenna output and input terminal the protected device.
- The ground terminal as short as SPD welding ground wire (conductor area of not less than 4mm2), and the other end connected to lightning protection system reliable ground bus, grounding resistance of less than 4Ω.
- The product is waterproof, but when used outdoors day fed mine should also pay attention to rain, must not let the rain immersed in its internal cause corrosion damage.
- The product requires no special maintenance. When the system fails to work, then check SPD can be removed, if restored to the state before after using the system back to normal, then the SPD has been damaged and must be replaced immediately.
