Zenith15/25 Pro | 6Safety Directions
DANGER
If the product is used with accessories, for example on masts, staffs, poles, you may increase the risk of
being struck by lightning. Danger from high voltages also exists near power lines. Lightning, voltage
peaks, or the touching of power lines can cause damage, injury and death.
Precautions:
• Do not use the product in a thunderstorm as you can increase the risk of being struck by lightning.
• Be sure to remain at a safe distance from electrical installations. Do not use the product directly under
or close 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.
• If the product has to be permanently mounted in an exposed location, it is advisable to provide a light-
ning conductor system. A suggestion on how to design a lightning conductor for the product is given
below. Always follow the regulations in force in your country regarding grounding antennas and masts.
These installations must be carried out by an authorised specialist.
• To prevent damages due to indirect lightning strikes (voltage spikes) cables, for example for antenna,
power source or modem should be protected with appropriate protection elements, like a lightning
arrester. These installations must be carried out by an authorised 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 cables and supply cables, for example, instrument - antenna.
Lightning conductors Suggestion for design of a lightning conductor for a GNSS system:
1) On non-metallic structures
Protection by air terminals is recommended. An air terminal is a pointed solid or tubular rod of
conducting material with proper mounting and connection to a conductor. The position of four air
terminals can be uniformly distributed around the antenna at a distance equal to the height of the air
terminal.
The air terminal diameter should be 12 mm for copper or 15 mm for aluminium. The height of the air
terminals should be 25 cm to 50 cm. All air terminals should be connected to the down conductors. The
diameter of the air terminal should be kept to a minimum to reduce GNSS signal shading.
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.

CAUTION
During the transport, shipping or disposal of batteries it is possible for inappropriate mechanical influences
to constitute a fire hazard.
Precautions:
Before shipping the product or disposing of it, discharge the batteries by running the product until they
are flat.
When transporting or shipping batteries, the person in charge of the product must ensure that the appli-
cable national and international rules and regulations are observed. Before transportation or shipping
contact your local passenger or freight transport company.
WARNING
High mechanical stress, high ambient temperatures or immersion into fluids can cause leakage, fire or
explosions of the batteries.
Precautions:
Protect the batteries from mechanical influences and high ambient temperatures. Do not drop or immerse
batteries into fluids.
