SER’S MANUAL
1 GENERAL INFORMATION
1.1 SAFETY NOTICES
To avoid risks of electrical shocks or fire, only qualified personnel should execute the procedures specified in this manual.
When the protective covers of any device or component connected to a 110 / 240 VAC source by a power cord are removed, voltages and currents dangerous to life may be exposed.
Contact with 110 / 240 Volts of alternating current and associated direct current and voltages can be fatal.
CAUTION
To reduce the risks of electrical shock, do not remove the cover (or the back). Refer, for servicing, to qualified service personnel. This installation should be done by a qualified person and should comply with to all local applicable laws.
Beryllium Oxide
It is dangerous component if inhaled, eaten or put into direct contact with skin, especially if the skin is cut or wounded. Special care is required in handling beryllium material in order to NOT produce any dust, particles, fumes etc. etc. Whenever beryllium material is broken it is extremely important to collect all parts in a carefully sealed and marked container for discharging in a specific way through controlled channels. All above operations have to be affected using gloves and tongs, with special care taken not to produce dust. After handling beryllium components it is essential to wash hands carefully.
Beryllium compounds are used in RF Connectors.
MOZART SERIES –FM Exciters/Transmitters - U
SER’S MANUAL
1.2 FIRST AID IN CASE OF ELECTROCUTION
Do not touch the victim until the electrical circuit has been interrupted to make sure the person is isolated. If this is not possible, move the victim away from the conductor by using insulated material.
If respiration is interrupted, artificial respiration must be applied (mouth-to-mouth respiration). Lay the patient on his back, feet elevated above the level of the head, chin up and head back.
Call a doctor urgently
In case of a mouth wound it may be necessary to apply mouth-to-nose respiration, blocking the patient’s mouth.
In case of face wounds the need for manual artificial respiration may arise. Push down on the chest of the prostrate patient whilst moving the patient’s arms up and out.
If the victim has also suffered burns then, without obstructing breathing, proceed as follows:
Do not remove clothing from burn wounds.
If possible gently pour cold water over wounds to relieve pain.
Do not use any medication.
Call for urgent medical assistance.

SER’S MANUAL
2 FM EXCITER GENERAL DESCRIPTION
The MOZART FM exciter/transmitter is the result of the development of the MSE (Magnetic Sound Enhancer) technology together with the improvements in the FM modulation and using high performances PFC filters for the AC/DC conversion. This unit is ideal as stand alone unit for low power transmissions or suitable as high performance exciter in modular transmitters. This unit has been developed with the Green RF technology which increases the efficiency of the amplification part reducing the dimensions and power consumption without modifying the quality of the transmission. The main advantages of this technology are:
- High RF efficiency
- Lower heating (lower necessity of air conditioning in the installation room)
- Higher devices safety
- Higher total reliability
- Lower AC power consumption
An user friendly interface with the combination of leds and LCD display offers a very easy method to control the MOZART main parameters with a metering accuracy that helps the user to install the unit and check its status even in case he doesn’t have expensive test equipments.
In case of fault of the unit or antenna system, the protection system lowers automatically the output power, in order to bring back the operating conditions to a safe area without causing a system shut down, and it indicates on the front panel display the alarm message.
The protection system reduces or stops the output power in case of:
- V.S.W.R. too high.
- Heatsink temperature too high or cooling stop (OVER HEAT).
- Missing Enable command (in case of combination with external units like control logic units)
MOZART SERIES –FM Exciters/Transmitters - U
SER’S MANUAL
The switch-mode power supply is largely oversized and guarantees a regular operation even in the presence of wide main voltage fluctuations. The systems cooling grants a safe operation even in hard climatic conditions.

4 INSTALLATION AND ACTIVATION
4.1 INITIAL CHECK
The equipment becomes the property of the customer when the equipment is delivered to the carrier. Carefully unpack the transmitter. Perform a visual inspection to determine that no apparent damage has been incurred during shipment. All shipping materials should be retained until it is determined that the unit has not been damaged. Claims for damaged equipment must be promptly filed with the carrier or the carrier may not accept the claim. The contents of the shipment should be as indicated on the packing list. If the contents are incomplete, or if the unit is damaged electrically or mechanically, notify both the carrier and the supplier.
CAUTION: Before switch the equipment on, ensure that all RF Loads, RF cables and connectors are properly connected. To prevent damage to the amplifiers, it is essential that either the feeder and antenna system or the dummy load have a good in band return loss. Failure to observe the above caution and also the installation instructions of this amplifier may cause damages to the amplifiers for which the supplier cannot be considered responsible.

PREVENTION OF ACCIDENTS
When it is used in normal applications and within the parameters defined in the technical specifications, this equipment does not endanger health and safety, provided that normal operating and engineering safety practices are observed and that it is used only by authorized, trained and qualified personnel.
THERMIC AND ENVIRONMENTAL CONDITIONS
- A too high environmental temperature (in any case not higher than 45°C) shall cause a non­adequate rack cooling putting the equipment in hard working conditions.
- An air conditioner should be installed to keep the room temperature constant even in case of external temperature variation.
22 /87
4.2 CONNECTIONS
Install the transmitter so that the space over and under the equipment is sufficient for the cooling air to flow through. Before installing the equipment always make sure that the transmitter is not powered. This has the purpose to prevent electrical shocks to the operators and damage to the equipment. Before carrying out any other electrical connection, connect the rack to the station ground.
Connect the transmitting antenna cable or the cable related to the connection of the output
filter to the output connector of the unit (in the latest case connect the output of the filter to the transmitting antenna) using a 50 Ohms coaxial cable.
In case the transmitter is not connected to an external control unit, check that the ENABLE
connector on the back panel is correctly inserted.
Connect the power cord to an operating source. Make sure that the power supply source
provides the nominal voltage prescribed.
Note: the unit is designed to operate with the nominal voltage ±15%. We suggest the installation of spike suppressors, line conditioners, isolation transformers, AVR and/or UPS or other devices useful to protect the equipment from eventual damages that can be caused by the mains fluctuations.
