4.2.4 Terminal installation
– Near-field obstructions
This is a conservative measurement for the site clearance for the Antenna. Note that this only applies to the “Near-
field” region, less than 5 metres distant from the panel antenna face.
Figure 23 - Clearance zone in the immediate vicinity of the antenna
Note: These clearance zones apply on both vertical and horizontal paths of the installation.
It is required to provide a clearance zone of 660mm = 66 cm of clearance if the radio terminal is installed on a flat
rooftop or close to any obstacles.
rooftop or close to any obstacles.
4.3 Grounding
The terminal must be properly grounded.
Two screws are provided on the rear housing of the terminal to facilitate correct
grounding. To fasten the grounding cable onto the terminal, use a screw post and
serrated washer combined with an M8 nut.
Connect the terminal to the connection points nearest to the building-to-earth ground
point. The grounding conductor must be as short as is practical and should not
exceed 6 m (20 ft). For installations in the USA, refer to Articles 810 and 830 of the
National Electrical Code. For installations in Canada, refer to Section 54 of the
Canadian Electrical Code. For installations in all other countries, refer to the in-
country safety standards and regulatory requirements.
