3. Safety Pracces and Provisions
3.1 Scope of this Chapter
This chapter describes various safety pracces.
3.1.1 Preventing Overexposure to RF Energy
To protect against overexposure to RF energy, install the radio units so as to provide and maintain minimal
separaon distances from all persons.
When the system is operaonal, avoid standing directly in front of the antenna. Strong RF elds are present
when the transmier is on. The radio unit must not be deployed in a locaon where it is possible for people
to stand or walk inadvertently in front of the antenna.
3.1.2 Grounding
All RADWIN products should be grounded during operaon. In addion:
• All ODUs should be grounded by a wire with diameter of at least 14 AWG.
• The ground lug on an IDU‐H should be connected to the protecve earth at all mes, by a wire with a
diameter of 18 AWG or wider.
• Rack‐mounted equipment should be mounted only in grounded racks and cabinets.
Further, you should ‐
• Always make the ground connecon rst and disconnect it last
• Never connect telecommunicaon cables to ungrounded equipment
• Ensure that all other cables are disconnected before disconnecng the ground
3.1.3 Protection against Lightning
The use of lightning protecon is dependent on regulatory and end user requirements. All RADWIN outdoor
units are designed with surge liming circuits to minimize the risk of damage due to lightning strikes.
RADWIN recommends the use of addional surge arrestor devices to protect the equipment from nearby
lightning strikes.
3.1.4 General
• It is recommended that installaon of outdoor units be contracted to a professional installer.
• Before working on equipment connected to power lines or telecommunicaon lines, remove jewelry or
any other metallic object that may come into contact with energized parts.
• Use extreme care when installing antennas near power lines.
• Use extreme care when working at heights.
• When using an AC power source for RADWIN devices, always use the AC power adapter supplied by
RADWIN.
• Use the right tools!
• Do not mount an radio unit upside down or horizontally. Doing this may void you product warranty.
