ITE PLANNING
All installers must perform a full site inspection and plan carefully prior to the physical installation of an
A060-Mini
®
system.
• This preparation must include:
• Evaluating the most appropriate location for the installation of the terminal.
• Identifying an appropriate mounting structure (wall or mast) for each terminal.
•
Planning the cable routing from the network component to the terminal.
3.1 Terminal location
When selecting the best terminal location the following factors should be considered:
• Accessibility (e.g. roof)
• Type of mounting (e.g. wall or pole)
• Grounding connection point
• Cable runs (max. 100 m / 328 ft)
• Line of sight
Use of given protection against sun, rain, etc. will increase the A060-Mini® performance.
3.2 Line of sight
To ensure a clear line of sight, there must be no obstructions between the two terminal locations. The
required clearance can be established visually using the following table

:
3.3 Link distance / Link availability
The link distance is directly related to the weather conditions. The affordable link availability is influenced
by the following environmental conditions:
• Rain:- the less, the better
• Temperature:- the higher, the better
• Air pressure:- the lower, the better
Knowledge of the link distance (line of sight) is important in estimating link quality.
For the rain regions in your country, see appendix A.4.

3.4 TERMINAL MOUNTING OPTIONS
3.4.1 Wall mounting
The wall mounting location should be strong enough to secure the terminal to the
wall, taking into account all foreseeable environmental conditions (e.g. wind,
rain, ice).
Depending on the material to which the bracket is mounted, differently sized
mounting hardware may be necessary. To mount the terminal onto the bracket
use the enclosed M6 bolts. The bracket allows a tilt angle of +/- 50° in both axis.
