This section describes mounting kits for installing AAUs on a pole, a wall, and the top of a pole.

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.

l When an AAU is installed on a pole, M8x80 expansion anchor bolts are not required.

l When an AAU is installed on a wall, steel belts are not required. Therefore, you need to remove the steel

belts from mounting kits.
