All ELENOS s.r.l products are compliant with the safety standards required for this type
of equipment.
2.1 Safety precautions
The user must follow also the safety precautions listed below:
DThe original configuration of the equipment must absolutely not be modified. On
receipt of the same equipment it is essential to check whether the supply is compliant
with the order’s specific terms and in case of nonconformities please report it immedi-
ately Elenos Srl.
DProtective devices must not be disconnected (with exception of their replacement),
altered or modified without authorization.
DCheck all protective devices periodically after the occurrence of a fault (e.g. devices
against excess voltage, against excess currents, circuit breakers, etc.).
DTo guarantee safety of the personnel and to protect the equipment from damages it
is absolutely forbidden to put it into operation and/or to use it while the doors are open
and/or without the partial or whole presence of protection panels and/or without
grounding connection, which must always be of extremely high quality and in accor-
dance with regulations in force. It is also forbidden to disconnect and/or to alter the
equipment’s means of protection.
DBefore starting any operation, the equipment must be disconnected from the mains.
Disconnection must be verified via visual inspection.
DThe equipment must be powered exclusively with the appropriate voltage. An incor-
rect power voltage can cause irreparable damages to the equipment and to the per-
sonnel working with it. This same information is reported on the product’s nameplate,
which is generally located upon its casing. In no case must the name plate be
removed, even if the equipment is resold.
DThe equipment must be powered by an electrical system which is compliant with the
regulations in force.
DOn the equipment can be found further pictograms reporting safety warnings that
must be carefully followed by anyone that has to work with it. The lack of respect for
rules here described exempts the Constructor from all liability for all possible dam-
ages or accidents occurring to persons or property and place responsibility to the user
himself.

LUM OXIDE. Please be aware that in some countries rules for storing and disposing
of hazardous materials may apply.
DFollowing a visual check, if any component seems damaged, fractured or not intact,
the utmost care must be taken when coming in physical contact through hands or
other means with the equipment.
DPlease ensure that any person in charge of the use or the maintenance of a trans-
mitter presenting one or more parts under hazardous voltage is able to perform arti-
ficial respiration and cardiac massage; all the staff must be trained on how to pro-
vide first medical aid in case of emergency. It is strongly advised to hang in a visible
position an informative panel reporting clear instructions regarding first aid’s proce-
dures for the rescue of people injured in a work accident and to supply rooms where
electrical equipment is present with first aid kits. It is strongly advised to organize
an intervention plan in order to ensure a quick connection with local public or private
first aid institutions so to be easily available for all the people hosted within the site.

WARNING:
CALL FOR MEDICAL ASSISTANCE AS SOON AS POSSIBLE IN ALL CASES
2.3 Workplace characteristics
2.3.1 Room characteristics
In order to work freely on the equipment and to be able to perform the relative installation
or maintenance operations, it is necessary to keep a minimum distance from the walls on
all sides of the machine.
The room must be equipped with an appropriate system of clean and dust−filtered air ven-
tilation with a flow rate suitable for the characteristics of the equipment operating in the
room itself.
Outgoing exhausted air must be conveyed directly outside. If the duct’s length or size is
such to presume it may be causing a consistent loss of load to the air flow rate it is neces-
sary to add an extraction apparatus. At the conveyor’s outlet intrusion protection devices
must be provided against insects or other kinds of animals and suitable precautionary
measures against liquid or other materials intrusion must be applied.
The equipment can operate properly if the temperature ranges from −5oC to +45oC (23oF
to 113oF), with 95% RH non−condensing at +40oC (104oF).
2.3.2 Electrical system features
The electrical network installation has to be set in accordance with the regulations in force.
The power supply network must allow an appropriate power provision according to the
laws in force in the Country of installation on the quality of the electrical energy supply
service.
It is highly recommended to use a transformer/network separator and a reduction network
for discharging high voltage.

Safety 17
Provide a protected under load disconnector (circuit breaker or fuses) with appropriate
disconnection power and capacity according to the absorption characteristics of the
equipment model.
Use cables of an appropriate size with respect to the rated absorbed current.
Earth connection must be performed according to the applicable laws.
Special care must be applied to the earth connection of the antenna system since it is
exposed to electrical atmospheric events.
Never forget that despite the earth connection of the equipment frame and the whole
antenna system, it is always dangerous to operate on the equipment in the event of bad
weather with atmospheric discharge. In fact, in the event of high energy discharge
(lighting), the equipment frame can instantly reach very dangerous voltage levels, due
to the earth connection inductance.
For this reason, the equipment should be installed in rooms accessible to maintenance
personnel only and for the time necessary for repairs and checks only.

2.4 Exposure evaluation
Exposure assessment requires the identification of electric field values in places where
the presence of people may occur.
The field values must refer to the type of stay and the exposed subjects, according to the
provisions of current legislation.
The identification of the electric field values can be carried out in various ways, depen
ding on the need for precision and the fact that one intends to perform a prediction, or a
subsequent verification.
We intend to provide below elements that may be useful in the evaluation and measure-
ments of electromagnetic fields, with particular reference to sound and television broad-
casting systems.
2.4.1 Calculation in the free space
A first approximate evaluation can be made by placing the following hypotheses:
i) source located in far field
ii) absence of obstacles
The first hypothesis (i) must be previously verified by applying the equation:
1.
where “d” represents the distance between source and evaluation point, “D” the physical
dimension of the source and “l” the wavelength of the field.
Under these hypotheses, the electric field at distance “d” from the source is:
2.
where “Pt” is the power transmitted (ERP) in the direction of the evaluation point.
Introducing the polarization of the electric field, impressed by the particular type of
antenna used in transmission, the relation 2 must be applied to the three components Ex,
Ey, Ez of the field; the expression of the total electric field becomes:
3.

Safety 19
=+Etot1
2Etot2 2Etoti 2Etotn 2
+ +EtotN
In the specific case of broadcasting plants for sound and television broadcasting, the fol-
lowing recurrent characteristics can be found:
a. the source is not isotropic, so the ERP should be calculated in the direction of the evalua-
tion point
b. in the case in which the worst case of exposure is concerned, it can be applied the
expression 2 in which the maximum transmitted ERP power is considered, regardless
of the direction, ignoring the radiation characteristics of the antenna system in the hori-
zontal and vertical plane
c. the polarization of the field is almost always vertical in the case of systems for sound
broadcasting, while it can be vertical, horizontal or mixed in the case of television broad-
casting. In all cases, the decomposition of the power transmitted in the various polariza-
tion components and the subsequent recombination by means of formula 3 allows,
firstly, to disregard the polarization of the field and to directly apply the expression 2
d. in the case of multiple sources, the total expression

The following table gives an indication of the first approximation of the field value as a func-
tion of the power (in W) transmitted by the source and distance (in meters); the values
shown (all in V/m) represent the worst case (see point)
