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.
