If the accessories used with the product are not properly secured and the product is subjected to
mechanical shock, for example, by blows or falling objects, the product may be damaged, or people may
sustain injury.
5.5.3 Lightning Hazards
WARNING:
If the product is used with accessories, for example, masts, staffs, or poles, you may
increase the risk of being struck by lightning. Danger from high voltages also exists near
power lines. Lighting, voltage peaks, or the touching of power lines can cause damage,
injury and death.
⚫
Be sure to remain at a safe distance from electrical installations. Do not use the product directly under or
in close proximity to power lines. If it is essential to work in such an environment, contact the safety
authorities responsible for electrical installations and follow their instructions.
⚫
To prevent damages due to indirect lightning strikes (voltage spikes) cables, for example for antenna,
power source or modem must be protected with appropriate protection elements, like a lightning arrester.
These instructions must be carried out by an authorized specialist.
⚫
If there is a risk of a thunderstorm, or if the equipment is to remain unused and unattended for a long
period, protect your product additionally by unplugging all systems components and disconnecting all
connecting cable and supply cables.
⚫
If the product must be permanently mounted in an exposed location, it is advisable to provide a lightning
conductor for the product as described below. Always follow the regulations in force by your country
regarding grounding antennas and mast. These installations must be carried out by an authorized
specialist.
5.5.3.1
Lightning Conductors
Suggestions for design of a lightning conductor for a GNSS system follow:
5.5.3.1.1
On Non-Metallic Structures:
On Non-Metallic Structures, protection by air terminals is recommended.
1. An air terminal is a pointed solid or tubular rod of conducting material with mounting and connection to a
conductor.
2.
The position of four air terminals must be uniformly distributed around the antenna at a distance equal to
the height of the air terminal. The air terminal diameter must be 12mm for copper or 15mm for aluminum.
The height of the air terminals must be 25cm to 50cm.
3.
All air terminals must be connected to the down conductors. The diameter of the air terminal must be
kept to a minimum to reduce GNSS signal shading.
5.5.3.1.2
On Metallic Structures:
Protection is as described for non-metallic structures, but the air terminals can be connected directly to the
conducting structure without the need for down conductors.
5.5.4 Disposal
If the product is improperly disposed of, the following can happen:
⚫
If polymer parts are burnt, poisonous gases are produced, which may impair health.
⚫
By disposing of the product irresponsibly, unauthorized persons may use it in contravention of the
regulations, exposing themselves and third parties to the risk of severe injury and rendering the
environment liable to contamination.
CAUTION
The product must not be disposed of with household waste. Dispose of the product
appropriately in accordance with the national regulations in force in your country.
