  • Page 15: About Safety

    NX100 Pre-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

    NX100 Pre-installation Manual Use a proper lockout procedure to ensure that another worker cannot accidentally reapply power while you are performing maintenance on any part of the transmitter or site. Lightning Hazards Before opening the transmitter and touching internal parts, remove and solidly ground the antenna connection.

  • 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://www.nautel.com/Training.aspx,...
  • Page 18 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 NX100 Pre-installation Manual Marking Hazards Place warning signs close to any hazardous areas or systems (e.g., the feedline or the antenna system). Make the signs large enough that they cannot be missed. Provide signage in all languages used in the region.

  • Page 21 NX100 Pre-installation Manual Physical Protection Consider physical hazards to equipment at your site, including the transmitter. Ensure that equipment is protected from weather (e.g., rain or flooding), even during extreme weather events. Place equipment so that it is not in the path of swinging doors or high-traffic areas. Do not allow wheeled items like office chairs or tables with wheels in the transmitter room, as these may damage equipment if accidentally pushed or knocked over.

    Heating - see page 4-8 Air flow in the transmitter There are two configurations for drawing cooling air through the NX100 - open air cooling and closed air cooling. The NX100 has redundant cooling fans to aid each configuration in ensuring effective cooling.
  • Page 44 In this configuration, cooling air must be ducted to the intake grill and the exhaust air must be ducted away from the transmitter. Closed air cooling requires an optional panel (Nautel Part # 207-8211) to cover the filter cut-out in the rear door. This panel is available from Nautel.

  • Page 45: Cooling

    Note: Ensure hot air from the transmitter is not drawn back into the transmitter’s cool air intake. Cooling plant requirements In an NX100 system, heat is generated by both the transmitter and the transformer, and each may be cooled separately. The transmitter’s efficiency is typically 92% and the transformer’s efficiency is 98%.
  • Page 46 112.5 8,533 Note: Although normal program audio is generally equivalent to 50-75% continuous tone modulation, Nautel recommends you design the cooling system for 100% continuous tone modulation, to allow sufficient overhead and for testing purposes. Page 4-4 Issue 3.2 2017-03-31...
  • Page 47 [typically 35˚C (95˚F)]. If so, note that the maximum temperature rise from the transmitter’s intake to exhaust is 20˚C. Nautel recommends you leave a gap between the top of the transmitter and the bottom of the exhaust hood, as shown in Figure 4.3.
  • Page 48 Cooling requirements Cooling system configuration Especially in warmer climates, Nautel recommends an air conditioned cooling system with ducted exhaust and free-air return. A split system air conditioner can be cost effective, provided the distance between the evaporator and condensor can be kept to a minimum. This configuration also minimizes dust and sand buildup within the equipment.

    167 kW (171 kVA). When operating at 100 kW with no modulation, power consumption is 111 kW. Power consumption for a specific station will depend on the programming format and the level of audio processing. Nautel recommends the ac power source have a 25% over- capacity to ensure adequate regulation.
