Protection requirements for a wall installation
If the ODU is to be mounted on the wall of a building, then in addition to the general
protection requirements (above), the following requirements must be observed:
• The equipment must be lower than the top of the building or its lightning air terminal.
• The building must be correctly grounded.
A schematic example of a wall installation is shown in Figure 2-4.
