Figure 19 Mounting WAT12 on top of pole mast

A long cable between different units (sensors, transmitters,

power supplies, and displays) can cause a lethal surge voltage, if a lightning
strikes in the vicinity. Always ground the mast equipment case close to the
mast with a short and low-resistance cable.

WARNING!
