If necessary, consult your weather station manual for instructions on discon-
necting the cables from your existing junction box and removing the existing 
junction box from its mounting location.

 

Note:

 

Do not throw away your existing junction box. The surge absorbers in the Protected Junction Box 
may “blow” if they absorb a direct or near lightning strike. In this case, you may use your old 
junction box to keep the station operating while the Protected Junction Box is repaired (provided 

 

your sensors haven’t “blown” as well).

 

We recommend that you label the end of each cable as you disconnect it. For 
example, write “WIND” onto one half of a small label (not provided) and then 
wrap that label around the anemometer cable about 3” (75 mm) from the 
phone plug. This will help you identify the cables when attaching to the Pro-
tected Junction Box.
