Safety Precautions & Declared Material
General Equipment Precautions
Use of controls, adjustments, or performing procedures other than those
specified herein, may result in hazardous radiation exposure.
When working with a FibeAir IDU, note the following risk of electric shock and
energy hazard: Disconnecting one power supply disconnects only one power
supply module. To isolate the unit completely, disconnect all power sources.
Machine noise information order - 3. GPSGV, the highest sound pressure level
amounts to 70 dB (A) or less, in accordance with ISO EN 7779.
Static electricity may cause body harm, as well as harm to electronic components
inside the device.
To prevent damage, before touching components inside the device, all
electrostatic charge must be discharged from both personnel and tools.
High Frequency Electromagnetic Fields!
Exposure to strong high frequency electromagnetic fields may cause thermal
damage to personnel. The eye (cornea and lens) is easily exposed.
Any unnecessary exposure is undesirable and should be avoided.
In radio-relay communication installations, ordinary setup for normal operation,
the general RF radiation level will be well below the safety limit.
In the antennas and directly in front of them the RF intensity normally will exceed
the danger level, within limited portions of space.
Dangerous radiation may be found in the neighborhood of open waveguide
flanges or horns where the power is radiated into space.
To avoid dangerous radiation, the following precautions must be taken:
•
During work within and close to the front of the antenna; make sure that
transmitters will remain turned off.
•
Before opening coaxial - or waveguide connectors carrying RF power, turn
off transmitters.
•
Consider any incidentally open RF connector as carrying power, until
otherwise proved. Do not look into coaxial connectors at closer than reading
distance (30 cm). Do not look into an open waveguide unless you are
absolutely sure that the power is turned off.
