CAUTION:
If the PC is in a building outside the main building (control
unit location), you must install an ADU and an additional
protector in each building. The ADUs and protectors
provide both the control unit and the PC with additional
protection against lightning, inadvertent contact with power
lines, and power currents induced by nearby power lines.
For more information, see the installation notes packaged
with the ADU.
