Lightning protection
When your transmitter is equipped with optional lightning protection, you
must connect a wire from the transmitter to ground as shown in Figure 17
to make the protection effective. We recommend that you use a size 8
AWG (American Wire Gauge) or KCM (Kilo Circular Mils) bare or
Green covered wire.
Note that protection for temperature sensor leads is not provided by the
optional lightning protection.
