1. Lightning proof and surge signal proof
The product uses TVS lightning proof technology to prevent damage
from a lightning strike below 1500W and impulse surge signals. It is
also necessary to take note of the following precautions to ensure
electrical safety for all applications.
- Keep the communication cables at least 50 metres away from high
voltage equipment or cables.
- Position outdoor cabling under the eaves wherever possible.
- In an open area shield the cables in a steel conduit and attach a
single point ground to it. The use of trolley wire is not
recommended in such circumstances.
- Extra strong lightning proof equipment must be installed in the
event of a thunderstorm or if unit is located in close proximity to a
high voltage electrical substation.
- Ensure the building has the necessary lightning proof measures in
place before designing the system and choosing your cable runs.
Run any cables in accordance with national and industrial
standards.
