WARNING Consult local electricity professionals for the local and state legislation and regulations about grounding.
WARNING Ground the product and verify outdoor installation grounding periodically. Failure to provide proper grounding can result in injury or death from electrical shock and can severely damage the equipment.
WARNING Lightning protection is required to prevent injury and damage to equipment due to direct lightning strikes and lightning-induced current surges.
WARNING Ground remote units properly. A lightning strike through a communication wire can cause a lethal current surge.
WARNING A long cable between units (sensors, transmitters, power supplies, and displays) can cause a lethal lightning-induced current surge. Always ground the enclosure to a suitable grounded location with a short, low-resistance cable.
WARNING Do not perform installation or maintenance procedures when there is a risk of thunderstorm or lightning activity in the area.
CAUTION To prevent equipment damage, install an air terminal so that the tip is as high above the instruments and sensors as possible.
CAUTION Vaisala recommends an air terminal for all mast structures that reach 10 meters (33 feet). For mast structures that reach 6 meters (20 feet) or lower, an air terminal is recommended in regions with high lightning density. Especially in tropical or sub-tropical regions, a lightning protection system is a necessity.
The customer is responsible for supplying the accessories, such as grounding cables, power cables, and conduits for cables.
