  • Page 15: About Safety

    VX150 TO VX2 INSTALLATION MANUAL About Safety All Nautel transmitters are designed to meet the requirements of EN60215, Safety Requirements for Radio Transmitters. The philosophy of EN60215 is that the removal of any cover or panel that can only be opened using a tool is a maintenance activity, and that any person performing a maintenance activity is expected to be trained for that activity.

  • Page 16: Lightning Hazards

    VX150 TO VX2 INSTALLATION MANUAL Lightning Hazards Before opening the transmitter and touching internal parts, remove and solidly ground the antenna connection. WARNING: It is not enough to ground the antenna terminal with the antenna still connected. Even a small impedance in the ground strap will result in lethal voltages during a lightning strike.

  • Page 17: Safety Precautions

    Personnel must be familiar with the transmitter, so that they can avoid physical danger, and be aware of hazards to themselves and the equipment. Nautel offers a number of training courses covering the basic fundamentals of RF systems and transmitters, and the operation and maintenance of the transmitter. For more information about available courses and schedules, go to the Nautel website at http://support.nautel.com/training/, or ask...

  • Page 18: Site Safety

    Operation of safety interlocks (if installed) First Aid Nautel does not offer first aid training, since the hazards associated with high voltage and RF energy are not specific to the transmitter. However, the customer should provide first aid training to all personnel who have access to the transmitter site.
  • Page 19 VX150 TO VX2 INSTALLATION MANUAL Qualifying Site Personnel Make sure that personnel who have access to the site are qualified to work around electronics and high voltage systems. Ac Power Protection You should take steps to protect equipment from surges (over-voltage spikes) on the ac power lines.

    (and to protect the rest of your site equipment and your personnel). For detailed information about lightning protection, see the Nautel Site Preparation Manual, available from your Nautel sales agent, or online from the Nautel website.
  • Page 21 VX150 TO VX2 INSTALLATION MANUAL Earthquake Protection If the transmitter site is in a region that experiences any noticeable earthquake activity, take steps to prevent the transmitter from shifting or rocking during an earthquake. Even during minor earthquakes, rocking or movement of the transmitter is likely to damage the feedline connection, and could even cause a catastrophic failure of the ac power feed into the transmitter.
