Mounting Kits for an AAU Installed on a Pole or Wall
The same mounting kits are used for installing an AAU on a pole and installing an AAU on a wall. However, the procedure for installing an AAU on a pole is different from that for installing an AAU on a wall. The following figure shows the mounting kits for an AAU.
NOTE
When an AAU is installed on a pole or wall, the main bracket and attachment plate are required.
•When an AAU is installed on a pole, M8x80 expansion anchor bolts are not required.
•When an AAU is installed on a wall, steel belts are not required. Therefore, you need to remove the steel belts from mounting kits.

When an AAU is installed on a pole or the top of a pole, the AAU must meet the surge protection requirements. Otherwise, surge protection measures must be taken.
A direct lightning strike protection measure must be taken (that is, a lightning rod is installed) if AAU installation meets the following conditions:
•When the AAU is installed on a pole or the top of a pole, the distance between the top of the pole and the top of the AAU is less than 30 cm (0.98 ft).
•The AAU is not installed within the protection range of the lightning rod.
When a lightning rod is installed near the AAU installation position, the following conditions must be met:
•The distance between the lightning rod and the top of the AAU must be greater than 30 cm (0.98 ft).
•The lightning rod must be properly connected to the onsite ground grid.
•The AAU PGND cable must be routed along the inner side of the pole and is connected to the ground bar of the onsite ground grid.
•In addition to the above conditions, the lightning rod installation must meet other building surge protection requirements.
