Page 15: About Safety
VS2.5 Troubleshooting 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 VS2.5 Troubleshooting 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://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 per- sonnel who have access to the transmitter site.
Page 19 VS2.5 Troubleshooting 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 20 (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: Responding To Alarms
Operating with defective PAs or cooling fans - see page 1-26 • Replacing a suspect PWB, power supply or fan - see page 1-27 If none of the procedures and alarms described in this section address your problem, contact Nautel for assistance. See “Technical support” on page viii.
Page 22 VS2.5 Troubleshooting Manual Responding to alarms Remote troubleshooting Remote on-air troubleshooting consists of monitoring the transmitter's radiated signal using an on-air monitor or via a LAN connection, and observing the status of each remote fault alarm indicator. Information obtained from these sources should enable an operator to decide whether an alarm response may be deferred to a more convenient time, an immediate corrective action must be taken, or if a standby transmitter must be enabled (if one is available).
Page 23: Electrostatic Protection
VS2.5 Troubleshooting Manual Responding to alarms Electrostatic protection The transmitter's assemblies contain semiconductor devices that are susceptible to damage from electrostatic discharge. The following precautions must be observed when handling an assembly which contains these devices. CAUTION: Electrostatic energy is produced when two insulating materials are rubbed together.

VS2.5 Troubleshooting Manual Reading Electrical Schematics Unique symbols Nautel uses unique symbols on electrical schematics to describe logic (two-state) signals. These signals differ from single-state signals or analog signals that may have multiple values. Type of inputs and outputs On electrical schematics, names used to describe logic (two-state) input and output signals are prefixed with a # symbol.
