Safety Practices and Provisions
Preventing Overexposure to RF Energy
To protect against overexposure to RF energy, install the ODUs so as to provide and maintain
minimal separation distances from all persons.
When the system is operational, avoid standing directly in front of the antenna. Strong RF
fields are present when the transmitter is on. The ODU must not be deployed in a location
where it is possible for people to stand or walk inadvertently in front of the antenna.
Grounding
All RADWIN products should be grounded during operation. In addition:
• All ODUs should be earthed by a wire with diameter of at least 10 AWG.
RADWIN 2000 C Plus ODUs must be properly grounded to protect against lightning. It is
the user's responsibility to install the equipment in accordance with Section 810 of the
National Electric Code, ANSI/NFPA No.70‐1984 or Section 54 of the Canadian Electrical
Code. These codes describe correct installation procedures for grounding outdoor units,
masts, lead‐in wiring and discharge units. It also lays down the size of grounding
conductors and connection requirements for grounding electrodes. RADWIN 2000 C
Plus ODUs must be grounded to a Protective Earth in accordance with the Local
Electrical Regulations.
• The earth lug on an IDU‐H should be connected to the protective earth at all times, by a
wire with a diameter of 18 AWG or wider. Rack‐mounted equipment should be
mounted only in earthed racks and cabinets.
Further, you should ‐
• Always make the ground connection first and disconnect it last
• Never connect telecommunication cables to ungrounded equipment
