  • Page 13: About Safety

    VS300 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 14 VS300 Pre-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 15: 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 16 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 per- sonnel who have access to the transmitter site.
  • Page 17 VS300 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 18 (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 19: Description

    N+1 configurations. Antenna tolerance The VS300 will operate at rated power with a VSWR of 1.5:1. A higher VSWR results in a protective foldback of output power. The greater the VSWR, the greater the reduction in RF power. Remote control and monitoring You can monitor all key parameters of VS300 operation, as well as control common functions such as power output and exciter settings, from a remote location.

  • Page 20: Options

    Description Ac power The VS300 can operate from a 50/60 Hz, single-phase ac power source at voltages between 180 and 264 V ac, or between 90 and 132 V ac by purchasing an optional auto-transformer (Nautel Part # TZ117). For detailed electrical requirements (e.g., input power, maximum line current, etc.), refer to Table 5.1...

  • Page 25: Physical Requirements

    VS300 Pre-installation Manual Physical requirements Section 3: Physical requirements This section provides physical specifications for the VS300 transmitter and its components, and lists physical site requirements. This section includes the following topics: • Dimensions • Clearances - see page 3-2 •...

  • Page 26: Clearances

    Physical requirements Clearances Provide a minimum clearance of 61 cm (2 ft.) at the front and back of the VS300. Provide additional clearance for air flow at the sides of the VS300, particularly near the front panel where the primary cooling fan is located.

  • Page 27: Cooling Requirements

    Air flow in the transmitter Figure 4.1. The VS300 draws cool (intake) air through air filters in the sides. The air circulates through the switch-mode power supply (on the left), across the low voltage power supply and is exhausted by the PA fan. Warm air exits the transmitter through the grill at the rear. An air exchange rate of 70 CFM achieves acceptable intake/exhaust temperature rise.

  • Page 28: Cooling

    VS300 Pre-installation Manual Cooling requirements Cooling Do not allow the transmitter room ambient air temperature to exceed 50°C (122°F) at sea level. Cooler temperatures are recommended in order to improve the reliability of the transmitter. At higher altitudes, derate the maximum inlet air temperature as follows: •...

  • Page 29: Electrical Requirements

    Power consumption The input power requirement for the VS300 is 569 VA (for analog mode). Use Table 5.1 on page 5-2 to determine the maximum line current and maximum inrush current values for a given ac supply voltage.
  • Page 30 Observe local electrical codes when determining wire size and circuit breakers. Nautel recommends that you base your wire sizes and breaker ratings on the maximum line current for analog mode plus a nominal 25%.

  • Page 31: Station Reference Ground

    Connect the surge protector to the station reference ground using a similar low-impedance coper conductor. Ensure that the transmitter site’s grounding rods are adequate.

    This section describes requirements associated with the antenna and RF cabling to be used with the VS300 transmitter. For detailed information about protecting the antenna system from lightning strikes, see Nautel’s Recommendations for Transmitter Site Preparation Manual. Antenna feed line The antenna feed line interconnecting the transmitter and the antenna system should be a suitably rated coaxial cable.
