Warning: to ensure safe functioning of the equipment,
it’s absolutely mandatory to comply with the instructions of the
present chapter.
7.1 Checking the supplied parts
Before using your amplifier, make sure that the following parts are included in the packing:

The amplifier

The user’s manual (this manual)

RG58 N-N cable, 1 meter length, to connect the amplifier input [19] to the exciter output.

Power supply patch cable to be used to connect the power supply input of the exciter to the INTERLOCK AUX connector [20]
of the Archimede equipment. Only with Archimede 3000 and Archimede 4000.
In case some parts are damaged or missing, promptly contact your supplier.
7.2 General safety rules

Warning: in order to prevent serious damages to objects and people, the following rules must be strictly followed.

Although in most cases no special instruments are required, the equipment must be installed by skilled personnel only. To
make best use of the equipment and prevent damage to the unit, compliance with the instructions of the present manual is
mandatory. Should doubts or technical problems arise during the installation procedure, you are strongly recommended to
contact Italab or a local appointed agent/dealer.

Should you encounter any technical problems or be in any doubts about the installation procedure, Italab will be happy to
provide its qualified technical support service. We strongly recommend that no interventions must be carried out by personnel
not authorized by Italab.

As a rule, the user should not have access to the inner parts of the equipment. Tampering with the factory settings makes our
warranty null and void and might also affect the equipment performance, causing expensive damages.

No adjustments or internal settings are required for normal operations. The equipment shall be properly earthed and be
operated with all the covers closed to prevent electrical hazards and fully comply with EC, EMI and all local safety
requirements.

Never touch the inner parts of the equipment without first disconnecting it from the AC power line. Dangerous AC, DC and
radio-frequency voltages are available inside and become accessible when the covers are removed.
7.3 Placing the equipment
7.3.a Choosing the proper room and location

Install the equipment in a dry, sheltered but well-ventilated room away from dust, moisture, insects, rodents and vermin (e.g.
mice).

Room size shall be such that the equipment can be placed in an upright position and that the technical personnel can easily
carry out routine or extraordinary maintenance.

Place the equipment as close as possible to the antenna in order to prevent excessive power loss in the cables. If this is not
feasible, use antenna low-loss cables of suitable cross-section.

Vents in the walls and any other openings shall be fitted with metal grids to keep rodents and insects out and with a dust filter.
Make absolutely sure that no water could penetrate through the vents or the air exhaust duct or the antenna-cable grommet,
and that the floor cannot be flooded during heavy rainfall.
7.3.b Environmental Conditions

In order to achieve the best possible performance in terms of power, life span, etc., the ideal room temperature should range
between -10°C and + 45°C. It is advisable to install in the room a min-max thermometer to display any variation.

The room must be ventilated to ensure that the temperature never exceeds 45°C. Such conditions CANNOT be generally met
when the exhaust cooling air is not pushed outside and is instead fed back into the room. This is even truer if more than one
unit is installed in the same location. An efficient ventilation system is thus required in the room. Air exchange in the room shall
have a minimum flow-rate of 500 meters per hour or more.

As a rule, if the equipment is fitted in a rack, the rear cover cannot be secured. If it is required that the equipment be totally
enclosed, a forced ventilation and air extraction system must be provided. In order to assist the air flow an exhaust ventilation
system with a flange must be connected to a hot air exhaust duct communicating with the exterior. In this case, bear in mind
