If you install the equipment in tropical, marine, or cold environments, keep the equipment within its specific operating conditions. To avoid dust, dirt, or water from entering the equipment, tighten the cable glands properly.
Warning Using a long cable between different units (sensors, transmitters, power supplies, and displays) can cause a lethal surge voltage, if a lightning strike occurs in the vicinity. Always ground the mast equipment case close to the mast with a short and low-resistance cable.
