Lightning strikes and lightning-induced current surges can result in injury or death and damage the device or system. Ground the device or system properly, including any remote units, and install lightning protection.

WARNING

Electricity hazard

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.

Lightning strikes can result in injury or death. Do not perform installation or maintenance procedures when there is a risk of thunderstorm or lightning in the area.

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. Install the air terminal so that the tip is as high above the instruments and sensors as possible.

The customer is responsible for supplying the accessories, such as grounding cables, power cables, and conduits for cables.
