Install the junction box

Step 7. Install the junction box
Note
The outside screw on the junction box cover disables the locking
mechanism. If the junction box is not locked, you can open the
junction box by pressing the tab located on the opposite side and
lift the cover.
Warning
Run indoor wiring from the junction box directly into the
structure in the shortest distance practical. Wires from the
junction box to the building interior should enter the building
almost immediately after exiting the junction box. (See Figure
19.)
Warning
Do not run RAU or junction box ground cables inside a building.
The junction box is the interface between the outside cables and
the inside cables. The junction box must be located on the
outside of the building immediately at the point where the
indoor cables reach the outside of the building.
When properly grounded, the junction box minimizes damage
to the telephone and lowers the risk of injury to the user in the
event the RAU or its cabling are struck by lightning in an
electrical storm.
The junction box may not adequately protect the user if the
RAU or its cabling are struck by lightning while the phone is in
use. Therefore, QUALCOMM recommends that the equipment
not be operated or handled during an electrical storm, except
for brief calls in an emergency situation.
Warning
Even though the QGFSP includes grounding and circuitry to
protect equipment, facilities, and personnel from nearby
lightning, lightning is a highly unpredictable and dangerous
phenomenon. It is impossible to completely protect equipment
and personnel from lightning.
