Note 1: The microBTS has been tested to assure it meets the dust and water resistance
requirements of IP67 as specified by IEC Publication 60529. These tests were conducted using
closure caps attached to the cable ports. To assure the dust and water resistance level is
maintained, it is the responsibility of the user to select AC power, antenna, and IP backhaul
cable assemblies that have a dust and water resistance level of IP67 or higher. If user is uncertain
of cable manufacturers that meet this requirement, please contact ADC Technical Assistance.

microBTS. The accessory items may or may not be required depending on the application.
3.1
Strand Mount Kit
A strand-mount kit is available if the application requires that the microBTS be mounted from a
horizontal cable system. Mounting pads are provided on the side of the enclosure for securing a
pair of cable-attachment clips. Screws are used to secure the cable-attachment clips to the
enclosure. All fasteners required for installation are provided with the kit.

3.2
Lightning Protector
An external lightning protector is available separately for the microBTS. It is recommended that
a lightning protector be installed at the base station antenna port to reduce the chance of damage
to electronic components should a lightning strike occur. The lighting protector surge/antenna
port is an N-type female connector.

3.3
Solar Shields
A solar shield kit is available if the microBTS must be mounted in full sunlight for extended
periods of time with extremely high ambient temperatures. The solar shields attach to the
exterior of the microBTS enclosure and shade the enclosure from direct exposure to the sun.
The solar shields are constructed of sheet metal and are painted to match the color of the
enclosure. All fasteners and brackets required for installation are provided with the kit.
